PART II 
CLASSIFICATION AND DESCRIPTION OF 
SPECIES 
In the following pages all the genera of British Basidiomycetes are 
described, also one or more typical species in each genus. 
The analytical keys to the genera of Hymenomycetes are based upon 
Carleton Rea’s lucid paper, “ Outline of the Classification of the Hy¬ 
menomycetes,” published in 1904 in the Transactions of the Worcester¬ 
shire Naturalists’ Club. 
A few of the larger Ascomycetes are also described and illustrated. 
The times of appearance are given under the seasons, and are normal. 
A species may, under certain conditions, be found in winter, though 
stated to occur in autumn. 
The measurements of the sporophore, peridium, pileus, and ascophore 
are always those of diameter, unless otherwise stated, and those of the 
stem its height. The dimensions given are those of typical well- 
developed specimens. 
Limitations of space compelled the frequent use of technical terms in 
describing the species, but the glossary and the notes on the plates 
should make these easily intelligible.
