Part 1/2 of Engler’s Syllabus of Plant Families – Ascomycota provides a thorough treatise of the world-wide morphological and molecular diversity of the fungal phylum Ascomycota.
The Ascomycota (including lichenized forms) are the most diverse group of fungi, with a fascinating range of morphological and biological variation, distributed from the arctic tundra and subantarctic vegetation formations, to tropical rainforests and semi-deserts, to freshwater and marine ecosystems. The present volume is an updated synthesis of classical anatomical-morphological characters with modern molecular data, incorporating numerous new discoveries made during the last ten years, providing a comprehensive modern survey covering all families and genera of the Ascomycota including detailed family descriptions.
While the Fungi are not part of the Plant Kingdom, they are formally included within the classic Engler’s title “Syllabus der Pflanzenfamilien / Syllabus of Plant Families”, which comprised families of blue-green algae, algae, fungi, lichens, ferns, gymnosperms and flowering plants.
Engler’s Syllabus of Plant Families has since its first publication in 1887 aimed to provide both the researcher, and particularly the student with a concise survey of the plant kingdom as a whole, presenting all higher systematic units right down to families and genera of plants and fungi. In 1954, more than 60 years ago, the 12th edition of the well-known „Syllabus der Pflanzenfamilien“ (“Syllabus of Plant Families”), set a standard.
Now, the completely restructured and revised 13th edition of Engler’s Syllabus published in 5 parts and in English language for the first time also considers molecular data, which have only recently become available in order to provide an up-to-date evolutionary and systematic overview of the plant and fungal groups treated.
In our “molecular times” there is a vitally important and growing need to preserve the knowledge of the entire range of diversity and biology of organisms for coming generations, as there is a decline in “classical” morphological and taxonomical expertise, especially for less popular (showy) groups of organisms.
Accordingly, the 13th edition of Syllabus of Plant Families synthesizes both modern data and classical expertise, serving to educate future experts who will maintain our knowledge of the full range of Earth’s biodiversity.
Syllabus of Plant Families is a mandatory reference for students, experts and researchers from all fields of biological sciences, particularly botany.

Engler's Syllabus der Planzenfamilien is one of the classic botanical reference works, the first edition of which appeared in 1892 and the 12th in 1954. The first volumes of the 13th edition started to appear in 2009, and are in English unlike all earlier editions. If one can shake off the distaste of a major work on fungi appearing in such a series today, this volume on the Ascomycota has to be recognized as by far the most important overview of the phylum to have appeared this century, fleshing-out the latest “Outline of Ascomycota – 2009” (Lumbsch & Huhndorf 2010). This volume is essentially a systematic arrangement which includes descriptions of higher taxa now recognized down to and including that of family, with lists of accepted generic names (with selected synonyms) under each family name. Estimates of species numbers are given from genera upwards, explanatory notes are added where appropriate, and key references are cited. The descriptions at all ranks are much more detailed than the diagnostic ones in Kirk et al. (2008), and more conveniently placed in their systematic position rather than alphabetically, greatly facilitating comparisons.
The volume has been compiled at a time when, with the end of dual nomenclature in 2011, the process of incorporating generic names typified by asexually typified species into a single system is in progress and incomplete; this must be borne in mind when looking for particular genera. The authors have, however, endeavoured to cover the literature up to the end of 2014, with some works from 2015 weaseled in. As I know from personal experience in preparing editions of the “Outline” and the Dictionary of the Fungi, it is necessary to be practical and use a system termed here as a “pragmatic compromise, in this case between a conventional, morphologybased system and a phylogenetic system based on molecular data” (p. 8). In many cases, molecular data are lacking, and decisions on placements have still to be based on morphology. Molecular data do not, however, always result in neat pigeonholing, and phylogenetic trees can change as more taxa are included, but at least the Ascomycota backbone appears to be increasingly stable, with only one new class added in recent years (Archaeorhizomycetes). Specialists will have their own views on the detailed arrangements adopted, and it would be trite to be critical of particular decisions here. The key point is that here we have an updated overall system for the phylum, backed by descriptions, that can be commended for general use.
Three subphyla are accepted (Peziziomycotina, Saccharomycotina, and Taphrinomycotina), 17 classes, 97 orders, 406 families, and about 6 100 genera; together totaling about 57 000 species). The largest class is Lecanoromycetes (ca 14 900 species), followed by Sordariomycetes) ca 11500 species). The families themselves vary remarkably in size, the largest being Mycosphaerellaceae (ca 3 300 species) and Parmeliaceae (ca 2 760 species). Author citations are included for all ranks, but sadly without dates appended, a practice which has become almost a routine in major listings today; these would have been especially useful here as references to original places of publication of the names are often not included in the works cited. A few illustrations are included, some being fine colour macro-shots, and it would have made the work more appealing to field mycologists and plant pathologists in particular if more could have been provided. Fortunately, illustrations of examples for most families are provided by Cannon & Kirk (2007), whose text also has family descriptions; it serves as a valuable adjunct to this new work. Unlike earlier editions of the Syllabus, and understandably, no keys are included; this is the next mountain waiting to be scaled, to update the attempt made in 1995 (Hawksworth et al. 1995). Fortunately, there is a comprehensive index to taxa, occupying 31 pages at three columns of names per page, so that the placements of particular genera in the system can easily be ascertained.
The number of accepted orders has now more than doubled since the 1990s. This trend seems set to continue with two additional order names formally coined here (Thelocarpales and Vezdaeales) and several others introduced “ined.” (e.g. Rhizocarpales). The number may be expected to grow even further, not only as genera typified by asexual morphs are increasingly incorporated, but as positions of unassigned but accepted genera are clarified. For example, around 190 genera of Dothideomycetes still lack an order, and some 90 genera still appear “incertae sedis” under Helotiales. Some changes in taxonomy at the generic level are also presented; the suggested treatment for Teloschistaceae, which has 14 recently proposed genera placed in synonymy, is of particular note.
Bringing this work to completion has been an enormous achievement, and is a great credit to the dedication and meticulous work of the compilers, along with the many specialists they consulted on particular groups. All systematists dealing with ascomycetes will find this to be an exceptionally useful reference work, and really good value at such a relatively modest price; make sure you have one close to your desk.

In 2009, Wolfgang Frey started with the editorship of the 13th edition of Adolf Engler’s famous survey of the plant kingdom „Syllabus der Pflanzenfamilien/Syllabus of Plant Families“, for the first time in English. Although fungi are no longer part of the Plant Kingdom, they are included traditionally and formally with the classic Engler’s title. The first volume of the new edition published was Part 3 “Bryophytes and seedless Vascular Plants” (ferns and fern allies), followed in 2012 by Part 1/1 “Blue-green Algae, Myxomycetes and Myxomycetelike organisms, Phytoparasitic protists, Heterotrophic Heterokontobionta and Fungi p.p.”, in 2015 by Part 2/1 “Eucaryotic Algae [Glaucobionta, Heterokontobionta p.p. (Cryptophyta, Dinophyta, Haptophyta, Heterokontophyta), Chlorarachniophyta, Euglenophyta, Chlorophyta, Streptophyta p.p. (except Rhodobionta)]” and Part 4 “Pinopsida (Gymnosperms), Magnoliopsida (Angiosperms) p.p., Subclass Magnoliidae [Amborellanae to Magnolianae, Lilianae p.p. (Acorales to Asparagales)]. Now, 2016, part 1/2 “Ascomycota” is published, the most diverse group of fungi, distributed from the arctic and subarctic vegetation formations to tropical rainforests and semi-deserts, to freshwater and marine ecosystems. This volume indicates that it is possible to bring the new edition soon to an end. Missing parts include Part 1/3 “Basidiomycota”, Part 2/2 “Rhodobionta” and Part 5 “Seed Plants, Spermatophytes, Angiosperms p.p., Rosidae”.
With part 1/2 Ascomycota (including lichenized forms, the former “Lichenes”) a thorough treatise of the world-wide morphological and molecular diversity of these fungi is presented. As highly diverse as this phylum is the number of authors: H. T. Lumbsch (Chicago) and R. Lücking (Berlin) are responsible for the introduction, characterization, and the systematic arrangement of the Ascomycota, as well as the lichenized Ascomycota [Pezizomycotina (Arthoniomycetes, Coniocybomycetes, Dothideomycetes p.p., Lecanoromycetes p.p., Lichinomycetres)], W. Jaklitsch (Vienna) for the non-lichenized Ascomycota p.p. [Taphrinomycotina, Saccharomycotina, Pezizomycotina p.p. (Dothideomycetes p.p., Eurotiomycetes, Laboulbeniomycetes, Leotiomycetes p.p., Sordariomycetes, Xylonomycetes)], and H.-O. Baral (Tübingen) for the non-lichenized Ascomycota p.p. [Pezizomycotina p.p. (Dothideomycetes p.p., Leotiomycetes p.p., Orbiliomycetes, Pezizomycetes)] and lichenized Ascomycota p.p. (Lecanoromycetes p.p.). W. Jaklitsch and W. Frey (Berlin) provide the Synopsis of classification of the Ascomycota.
Most obvious on a first look for non-fungal specialists: the systematics of the Ascomycota has changed dramatically when compared to former textbook classification a decade ago. The phylum now contains three subphyla, the Taphrinomycotina, the Saccharomycotina, and the Pezizomycotina with a total of 18 formally recognized classes.
Responsible are phylogenetic revisions based on DNA sequence data which have become available recently and which have revolutionized the systematic classification at higher level dramatically, leading to a new understanding of fungal evolution and species delimination.
The systematic arrangement followed, therefore reflects the current state of understanding of the Ascomycota and provides an updated synthesis of classical anatomical-morphological characters and modern molecular data.
The text consist of six chapters: 1 Introduction, 2 Ascomycota (including introduction, characterization and systematic arrangement), 3 Synopsis of classification of the Ascomycota, 4 Systematic arrangement of the Ascomycota, 5 Taxonomic novelties, 6 Appendix. It is completed by 17 coloured plates with 149 photos (habit, details) of almost high quality. They give a first impression of the various taxa treated. Chapter 2 presents an excellent summary of the characters of the taxa of the phylum (sexual reproduction, asexual reproduction, ecology and distribution, evolution, importance and uses) and give valuable hints for a further reading (references).
The classes and all further taxa of Chapter 4 (main part) are arranged in alphabetical order. The total number of families is 406 (plus an additional 10 lineages at present not formally named), with approx. 6100 genera. Detailed descriptions for all families with estimates of species numbers at the family and genus level are given additionally (when possible).
Taxonomic novelties include the Thelocarpales Lücking & Lumbsch ord. nov. and Vezdaeales Lumbsch & Lücking ord. nov.
Volume 1/2 of the new ‘Engler’s Syllabus of Plant Families’ ‒ as the previous published volumes ‒ is a well done, well based and solid book. It represents an outstanding and modern, up-to-date synopsis of the Ascomycota and include an informative and well based summary on the different fungi lineages and the phylogenetic reconstruction that will serve as a prime reference for a long time. It is an important step towards a solid familiar and generic re-arrangement of the taxa for even less popular groups of organisms. This volume quickly will become an essential work in any library. It is an extremely handy source and a basic treatment for finding the most up-to-date classification, number of families, genera and further references, and most valuable for students, botanists, ecologists and researchers, interested in fungi (incl. lichens) diversity.

Gustav Heinrich Adolf Engler, 1844– 1930, was a German botanist and plant geographer. His best known publication (with Karl von Prantl) is Die natürlichen Pflanzenfamilien (The Natural Plant Families) published in parts from 1887 to 1911. In this work, Engler and Prantl provided a comprehensive system of plant classification that became widely accepted and was the principal one used in herbariums and elsewhere worldwide until the 1970s. Engler's Syllabus der Pflanzenfamilien, which first appeared in 1892 under a different title, is essentially an outline summary of the larger work. Taking on a life of its own, many subsequent editions of the Syllabus appeared, and it was continued by others after Engler's death. The most recent edition was the 12th in 1954. The 13th edition, the first in English, began in 2009 with the publication of Part 3, Bryophytes and Seedless Vascular Plants, and has continued with the release of additional parts in 2012 and 2015.
So why are we interested in a book about plants originally written by a botanist? Because, until rather recently, fungi were considered to be plants and so they, along with cyanobacteria, algae, and lichens, were treated by Engler.
This is the second of three (sub)parts of the Syllabus that deal, fully or in part, with fungi. Part 1/1, published in 2012, covered, along with a variety of nonfungus things, the Chytridiomycota, Zygomycota, and Glomeromycota. Part 1/3, forthcoming, will treat the Basidiomycota. The Ascomycota is, by far, the largest of the phyla of Fungi, comprising about 60% of all species in the kingdom. Of the roughly 65,000 known ascomycete species, about 18,500 are lichens. The others span the entire range of fungal life styles, including saprotrophs; parasites on plants, animals, and other fungi, including lichens; endophytes and endoliths; carnivores; and mutualistic associations with plants such as ericoid mycorrhizas and ectomycorrhizas.
The authors are well aware of the difficulty in producing such a comprehensive work when the classification of fungi, as well as that of other organisms, is undergoing such a rapid and widespread change as a result of the accumulation of data from molecular sequencing. Thus, they view this as nothing like the final word, rather as a snapshot of a work in progress. In the Preface, the editor of the series (Frey) describes the new edition of the Syllabus as “Following the tradition of Engler, and incorporating the latest results from molecular phylogenetics and phylogenomics, this completely restructured and revised 13th edition provides an up-to-date evolutionary and systematic overview of the fungal and plant groups.” The authors of this part further state that “phylogenetic revisions have revolutionized the systematic classification of taxa from phylum to species level and a new understanding of fungal evolution and species delimitation has emerged. These new insights are here treated in an integrated context of morphological and molecular data, providing an up-to-date synopsis of this phylum while acknowledging that the systematic classification of this group of Fungi is not yet fully settled.”
Be forewarned, this is not an enthralling page-turner. It is a reference work that will sit on your shelf until you need to learn something about an ascomycete whose name you have encountered for the first time or find out who is thought to be close cousin of whom. Following a onepage introduction, Chapter 2 provides a succinct summary of the phylum, Ascomycota, its modes of reproduction, ecology and distribution, evolution, and importance to humans. Chapter 3 consists of a 14-page synopsis of the classification of the Ascomycota. Chapter 4 makes up the bulk of the book (more below), Chapter 5 gives us two new order names, and Chapter 6 slips in some late additions and updates. An index to taxa completes the book.
Following the outline provided in Chapter 3, Chapter 4 cycles through the subphyla, classes, orders, and families, providing brief descriptions of each taxon, numbers of genera in each family, (often) numbers of species in each genus, and reference citations (there is a huge number of them). Other than for the three subphyla (Taphrinomycotina, Saccharomycotina, and Pezizomycotina), the entries are arranged alphabetically.
Scattered throughout the book are 8 line drawings, mostly of life cycles, and 16 color plates. Fifteen of the plates consist of multiple images (8–12) of macroscopic or microscopic features. They are mostly of high quality and my only reservation is that, in some cases, providing a close-up of a small feature prevents one from getting a picture of the whole organism or fruiting body. This book will be a necessity for anyone making a serious study of the ascomycetes and will no doubt find a place in most university mycology labs and libraries. Although it could well come in handy for many folks, the price is likely to prevent it from finding its way into the personal libraries of most amateur mycologists.

Die 13. Auflage von A. Engler's Syllabus der Pflanzenfamilien (1. Auflage 1887) erscheint seit 2009, nun in Englisch, mehr als 50 Jahre nach der 12. Auflage. Das Werk gibt in 8 Bänden eine gestraffte Übersicht über die aktuelle Systematik der Samenpflanzen, Farne, Moose, Pilze einschließlich Flechten und Schleimpilzen, Algen und Blaualgen, also der traditionell von der Botanik bearbeiteten Gruppen. Die einzelnen Bände wenden sich vor allem an die Interessenten der jeweiligen Gruppen, soweit sie taxonomisch und floristisch arbeiten. Die gesamte Reihe ist wichtige Referenz, wenn sich der Blick auf große Ausschnitte der Lebewelt richtet, etwa bei der Erstellung von Gebiets- oder Länder-Inventaren wie Checklisten und Roten Listen. Adressaten sind hier Institute, Organisationen, staatliche Ämter und kommerzielle Untersucher (Büros) in den Bereichen Diversitätsforschung, Naturschutz und Ökologie.
Band 1/2 behandelt die Ascomycota (früher Klasse der Ascomycetes), die Schlauchpilze. Mit derzeit rund 65000 beschriebenen Arten ist es die größte und hinsichtlich Gestalt und Biologie die diverseste Teilgruppe der Pilze. Sie umfasst Formen in allen terrestrischen und aquatischen Lebensräumen der Erde von den wenig-zelligen Hefen über die breite Palette der „Schimmelpilze“ und die Flechten bis zu „Großpilzen“ wie Becherlingen, Morcheln und Trüffeln. Die wiedergegebene Systematik vermittelt zwischen klassischer Morphologie und molekulargenetischen Befunden, beide zusammen der Weg zur Erfassung der globalen Diversität, in einer Zeit, da diese unter dem Einfluss des Menschen schwindet. Die sich ergebenden Differenzen zur herkömmlichen Systematik betreffen vor allem Rang und Abgrenzung der höheren Kategorien. Im Mittelpunkt der Bearbeitung steht die ausführliche Beschreibung der Familien mit Auflistung aller Gattungen weltweit. Ergänzende Angaben beziehen sich auf jüngste Entwicklungen in der Systematik und, soweit gegeben, auf die medizinische und ökonomische Bedeutung der Taxa. Auch die höheren Kategorien - Ordnung, Klasse und darüber - werden charakterisiert. Die Ebene der Klasse bildet jeweils ein Kapitel, das mit dem Literaturverzeichnis abgeschlossen wird. Die beigegebenen Fotos geben einen Eindruck von der Vielfalt der Formen.

Some lichenologists may be surprised by a work which includes a volume on lichenized and non-lichenized Ascomycota in its 13th edition that they may not have heard much about before.However, so-called cryptogams have been included in thiswork formore than 100 years due to the famous botanist,AdolfEngler,Director of theBerlinBotanicalGarden and Museum, who wrote a single volume himself which included all fungi (with lichens) on only 21 pages. It started in 1892 with a slightly different title and soon became a standard text with new editions every few years, the 6th edition appearing with minor alterations in 1909. The 7th edition in 1912 saw the inclusion of illustrations and therefore an extension of the fungal chapter to nearly 40 pages. Engler was supported by E. Gilg hereafter until the 11th edition in 1936 whichwas issued byLudwigDiels as a single volume.Only the 12th edition, edited by H. Melchior & E. Werdermann in two volumes in 1954 and 1964, contained a special chapter (15 pages) on lichens by F. Mattick.
After a break of about 60 years a completely newedition of several volumeswritten in English by well-known international specialists and edited byW. Frey has appeared. Fromthe former editions in German it follows the general concept, title and tradition of including the fungi as well as blue-green algae, myxomycetes etc.
The short introduction of 12 pages is followed by a synopsis of classification of the phylum Ascomycota on 14 pages. This continues with the systematic arrangement of taxa – the main corpus of the book. Here all accepted taxonomic entities to family level are described using morphological aswell asmolecular data. Taxonomic uncertainties are discussed and extended lists of references are separately given for every class. Accepted genera in every family are listedwith an estimation of the number of species in brackets.This part is illustrated by 7 plates of line drawing taken fromthe 12th edition and 17 plates of c. 150 new colour photographs of high quality. The orders Thelocarpales Lücking & Lumbsch and Vezdeales Lumbsch & Lücking are proposed as taxonomic novelties.
The text of the introduction and the systematic arrangement is written by Thorsten Lumbsch and Robert Lücking with contributions by the other two authors. The lichenized Ascomycota are treated by Lumbsch and Lücking, whereas the non-lichenized Ascomycota are partly written by Walter Jaklitsch of Vienna or Hans-Otto Baral of Tübingen.
This is a standard reference work mandatory for every honest botanical library. For lichenologists the parts including lichen photo-symbionts may also be of interest. Photoautotrophic eukaryotic Algae have been published as volume 2/1 in 2015, blue-green Algae are included in volume 1/1 published in 2012, andBasidiomycota are still in preparation.

The ascomycota comprise the numerically most important phylum of the fungal kingdom. They constitute well over 60% of the nearly 100,000 species of fungi known, and likely represent an even greater proportion of the estimated million(s) yet to be described. They are saprotrophs, parasites, lichen-formers, mycorrhizal symbionts, endophytes, and predators of invertebrates. A few are human pathogens, whereas others are sources of antibiotics used in combatting human pathogens. The ascomycota also include the fungus of greatest cultural and economic impact on humankind, the bread and beverage yeast Saccharomyces cerevisiae . The present volume offers an updated systematic scheme for this phylum extending below the level of order, with detailed descriptions of families and lists of included genera for each. With the infusion of molecular sequence data over the last couple of decades, the classification of fungi has undergone major rearrangements. that process is certainly not finished, but the broad scheme of higher taxa in ascomycota has reached sufficient stability to make a detailed treatment of this kind timely and useful. The authors of this volume are major figures in the phylogenetic and systematic study of the organisms in question and have collaborated with a great many mycologists worldwide. They are therefore well positioned to provide a consensus snapshot of the current state of the science.
The authors recognize 18 classes of ascomycota, subdivided into about a hundred orders containing a total of 406 families, within which about 4000 genera are listed. Somewhat surprisingly, there is no cladogram or similar diagram to summarize the systematic framework employed. Nor is there a unified reference list. Instead, a separate bibliography follows each of the 18 fungal classes treated, a format that can make the search for a particular reference somewhat frustrating. Since the book consists mainly of descriptions of families and orders, it will serve the user primarily as a reference tool. No glossary is included, so a reader not well versed in the terminology will need to refer to the Dictionary of Fungi or a mycology textbook. Seventeen color plates with numerous photographs, mostly of fruiting bodies and lichen thalli, provide valuable illustrations of representative taxa, while also off-setting the inevitable dryness of the character descriptions. The images are all of superb quality and contribute substantially to the book’s overall appeal. Future editions might usefully expand on this feature, particularly by including more images of the microscopic characters that gure so prominently in the family descriptions. Following the format of many classic works in the German scientific textbook tradition, digressive text is set off as short paragraphs in smaller type. Here, however, these paragraphs provide the real commentary amidst the lists of characters, and so might preferably be highlighted rather than relegated to a format of lesser prominence.
This volume forms part of a series with a long and venerable history in botanical science reaching back to the 19th century, revived recently in a new edition brought out by Gebrüder Borntraeger, an equally long- standing institution in German scientific publishing. The series was initiated by the botanist Adolf Engler, whose Syllabus der Pflanzenfamilien encompassed all groups of organisms considered plants at that time, including the fungi, cyanobacteria, algae, and myxogastria. Nowadays, of course, the bacteria are classified in a separate prokaryotic domain, while among the eukaryotes, the plantae, fungi, myxogastria, euglenoid algae, chlorarachniophyte algae, alveolate algae and stramenopiles are all placed in different supergroups (with a broad relationship among the latter three lately recognized). Obviously, Engler’s original concept of “plant” cannot be sustained in any conceivable sense, and especially not in a work dealing with biosystematics grounded firmly in contemporary phylogenetic principles. Well aware of this, the publisher and authors repeatedly acknowledge that fungi are clearly not plants under present concepts. But they do not say explicitly why they have chosen to retain the original series title in unaltered form. A less problematic option would have been to recast the new edition as simply PSB 63 (3) 2017 118 Engler’s Syllabus, or Syllabus of Biodiversity, or even Engler’s Syllabus of Plants, Eukaryotic Algae, Cyanobacteria, Fungi, and Slime Molds [etc.].
That issue aside, the decision to place the current series within the great tradition of its predecessors is commendable. Too often, the rapid pace of scientific advance tends to make us insecure and overanxious to prove our modernity by ignoring or rejecting the past. Yet we cannot fully appreciate the signicance of concepts in their present incarnation without considering their historical context, in the same way that we would not attempt to understand a structure or a taxon without considering its trajectory through time. The last edition (12th) of Engler’s Syllabus was published in the 1950s, not only well before the advent of molecular sequence data, but also before phylogenetic principles were consistently and rigorously applied to classification. The systematic scheme presented in this edition will therefore likely differ more profoundly from its immediate predecessor in the series than did any other previously.
Syllabus of Plant Families: Ascomycota is a significant reference work that research libraries and herbaria will wish to acquire, as will many mycologists and plant pathologists who study these organisms in a biosystematic context.
