About this book

Language: English with bilingual summary in English and German

Fungi of Cameroon is a contribution towards assessing the current macrofungal diversity associated with the ecosystems of Cameroon's southern forests, and evaluates the impact of deforestation and slash-and-burn on fungal communities and tracks the occurrence and changes to the fungal communities through the seasonal climatic variations (rainfall).

During three forays in different seasons, more than seven-hundred fungal samples were collected, all of which are described and characterised. 78% of these were basidiomycetes, while ascomycetes accounted for 21% of the samples. The identification of about 85% of all collected specimens with modern mycotaxonomic techniques has yielded a total of 271 distinct species, belonging to 110 genera in 58 families. Fungi of Cameroon provides compiled keys at the family, genus and species level, followed by micro- and macromorphological descriptions of different taxa, providing data on habitat, local and worldwide distribution where available. A full description is provided fore each species, supported by reliable line-drawings and often SEM images for ornamented basidiospores.

The overall recorded species were new to the Mbalmayo forest reserve, while 75 of the described species were new to Cameroon, and eleven new mycobiota were described, plus one combination. The greatest fungal diversity was observed in forest stands, declining towards fallows and cropland. A distinct reduction of the diversity of wood and litter-dependent fungal species can be observed where land conversion takes place which is a definite threat to fungal species. As expected, seasonal variations fundamentally influence and govern the fruition and composition of the fungal communities studied.

"[...] 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."
– Irmgard Krisai-Greilhuber, Austrian Journal of Mycology 16, 2007, p. 291-292

"This commendable effort characterizes the nongilled Hymenomycetes in Cameroon and represents the doctoral thesis (University Kassel) of the author. The printing quality is excellent and the English translation more than adequate [...] recommended for botanical/ mycological centers, university libraries and taxonomic specialists who work on the above fungal groups."
– Ed Setliff, Inoculum 60(2), April 2009

"[...] 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."
– Roy Watling, Mycotaxon vol. 107, 2009

"This book describes in detail the Aphyllophorales of the Mbalmayo forest reserve in Cameroon. 271 species have been recognised, including eleven being new to science. Keys are given to families, genera and species, as well as detailed descriptions and line drawings, habit and distributions data, as well as taxonomic notes. This work provides many new data from the African continent, where this kind of meticulous and detailed studies on Aphyllophorales are very much needed."
