The contributions presented during the International Symposium held at the University of Münster in March 1986 have just been published as volume 25 of the series "Bibliotheca Lichenologica". Most of the oral and poster presentations are included in this volume of 498 pages.

The contributions have been arranged in five chapters. The first, entitled "Developmental Morphology and Ultrastructure", is concerned with general morphology of lichen thalli and the problems of symbionts and their resynthesis. Reproductive strategies and structures and electron-microscopical descriptions of certain symbiontic structures are also included. The second chapter, "Biology and Taxonomy of Genera and Specific Groups", deals with morphology, ecology and classification of some interesting and new lichen taxa. The third chapter, "Ecophysiology", covers photosynthesis and water relation ships in lichens of different habitats and the occurrence of mineral elements in lichen thalli. The "Ecology and Distribution" chapter summarizes the contributions on certain groups of lichens occurring in the Southern Hemisphere and Europe. The concluding chapter "Chemotaxonomy" deals with the identification of lichen substances and their value in classification.
