The main part is the taxonomical treatment of non-gilled hymenomycetes found in the forest reserve of Mbalmayo. 140 species of Aphyllophorales, Gasteromycetes and heterobasidiomycetes are included: 11 gasteromycetes, 10 heterobasidiomycetes, 9 clavarioid fungi, 19 steroid fungi, 10 lentinoid fungi, 6 ganodermoid fungi, 14 Hymenochaetaceae and 61 Polyporaceae are documented. After an introduction into methods (incl. SEM and molecular biological identification where necessary) and characters used keys are presented to families, genera and species, respectively based on the samples found in the forest reserve. The species are thoroughly described in detail with macro- and microscopical characters, data on ecology, distribution and remarks. Every species is illustrated by line drawings of the main characters and additionally some with habit photographs and SEM pictures of spores, when these are ornamented. The arrangement reminds of the numerous publications by Leif RYVARDEN, who in fact made his huge expertise available to the author and collaborated in this study.
The analysis is based on transsects in three different seasons. The three surveys resulted in ca. 700 samples, 78 % basidiomycetes, 21 % ascomycetes. More than 271 species belonging to 110 genera in 58 families are recognised. Among the described species 75 taxa were new to Cameroon. Eleven species are described as new to science, one new combination is made.
Besides the taxonomic interest the author documents the macrofungal diversity in southern Cameroon forests, investigates ethnomycological knowledge in and around the forest reserve, studies macrofungal communities, their diversity and distribution in different land use types due to agriculture and forestry following a gradient of increasing disturbance, studies the impact of seasonal variations on macrofungal communities occurrence and abundance. The ecological and coenological data out of the study can be used to develop conservation strategies and management programmes for a sustainable use of the resource macrofungi in rainforest ecosystems.
Fungi of Cameroon is a high quality book. It is of interest for nature conservationists and a must for every mycologist interested in tropical non-gilled hymenomycetes.

The book is well organized with keys to major groups and then to genera within families. Each species is described by clear text and line drawings of microscopic features. For many species there are excellent photographs of macroscopic and microscopic characteristics. Some of these are taken with the SEM. The smaller than usual print size packs more information into a given space. The taxonomic breakdown is quoted as follows: “Gasteromycetes, 8%; Heterobasidiomycetes, 7%; Clavarioid fungi, 6.5%; Stereoid fungi, 13.5%; Lentioid fungi, 7%; Ganodermoid fungi, 4%; Hymenochaetoid fungi, 10%; and the Polyporaceae and allied fungi, 44%.” Eleven new or recently described species are included. A Latin description is given for three of these in this volume, viz. Clavulina arcuatus, Lentaria acuminata, and Pterula hyphoides. The others were first published elsewhere. Also, Phylloporia resupinatus is included as a provisional name and Scytinopogon parvus becomes a new combination. The paint and tooth fungi were beyond the scope of this volume.
With relentless deforestation and diminished biodiversity occurring around the world, this volume provides a lesson as well as a good foundation for further taxonomic studies in Africa and in the tropics. The book is reasonably priced and is recommended for botanical/ mycological centers, university libraries and taxonomic specialists who work on the above fungal groups.

The main part of the book (289 pp.) comprises excellent descriptions of the non-gilled hymenomycetes found along eight plotless transects of 1000 x 20 m in four land-use types (near primary lowland forest, old-growth secondary forest, cleared areas with fallow of different stages and cropland) within the Mabalmayo forest reserve, situated in southern central Cameroon. All are supported by clear and effective line drawings and keys. There are 140 species described including 11 gasteromycetes (Birds’ nest fungi and one stinkhorn) and 10 jelly fungi; 11 new species are described and a single new combination is made; and 75 are new records for Cameroon. The classification adopted is primarily on macro-morphology, using such groupings as stereoid fungi. stipitate stereoids, clavarioid fungi, etc. Such a treatment is useful, although it does not reflect natural groupings now revealed by molecular studies. This section is where the non-gilled part of the title is evident but the ‘topping and tailing’ of this descriptive data is full of equally important information. Although the full title is explanatory, I doubt whether the reader realises when opening the book what a mine of information there is between the pages, and so full appreciation of the work involved may not at first be appreciated. There is certainly more to this volume other than non-gilled forms, as information on such topics as the distribution and ecology of agarics and larger ascomycetes are also addressed. I was amazed at the fundamental differences between the mycological constituents of transects I have made and the author’s, as these were in areas not that distant from one another in Cameroon. However, explanations are offered for this and the fall off in mycodiversity between woodland areas, arable ones, etc.
The physical, climatic, and anthropogenic factors of the area are covered adequately, and the historical account of earlier collecting in Cameroon is an excellent distillate, appealing to a wider audience. I do, however, seriously wonder whether the taxonomic part should have been published separately from the details on collecting, monitoring, assessing mycodiversity, gathering meaningful ethnomycological data, and applying statistically sound techniques for analysis, as these include groups other than the non-gilled forms. Those accounts would be extremely valuable brought together as a separate publication as they would be of benefit to anyone collecting in the tropics, and not just Africa. Indeed, they should be read by all venturing into these parts of the world wishing to carry out mycological work. Perhaps this could be produced as part of the proposed extended project.
This is a well-documented publication worthy of the efforts of a wellseasoned mycologist, let alone just the subject of a thesis. 700 samples were analysed, 70 % basidiomycetes and 21 % ascomycetes. The time spent over all aspects covered must have meant the author spending many, many hours of the day collecting, identifying, and mulling over the finds. It was truly a labour of love – in all, 271 different fungi covering all groups were identified.
