AGARICALES 115 



1. Species with obtuse fold-like lamellae (Cantharelleae). 

 Trogia has a single small coriaceous species with brownish 



pileus and white hymenium growing commonly on fallen branches 

 of alder. 



Ca7itharellus contains the fleshy speces of this group, of which 

 the egg-yellow C. cantharelliis is the best known. It is very com- 

 mon in the forests of Germany and other parts of Europe whence 

 it is commonly carried to the markets, as well as in America. C. 

 cinnabarimis is a smaller bright orange reddish species.'^ 



To this section the species of Craterelhis (p. 100) will be added 

 when we attain to a natural classification of these plants. 



2. Fleshy species with anastomositig lamellae (Paxilleae). 

 Paxilliis is the only genus of this section. Of our ten species 



P. ijivolutus with a slightly tomentose pileus of a grayish-brown 

 color whose margin is involute, is regarded as edible. f 



3. ^)pecies with a dcliqitcscent pileus (Coprineae). 



The principal genus of this group is Coprinus, some species of 

 which are everywhere common. They may be readily recognized 

 from the fact that the pileus melts to a black inky fluid soon after 

 the maturity of the spores; for this reason they are often known as 

 ink-caps. All of the larger species and some of the smaller ones 

 are edible. The principal edible species are C. comatus, three to 

 nine inches high ; easily recognized by its cylindric form and its 

 shaggy pileus which is formed of yellowish-brown scales on a 

 whitish foundation ; young plants have an annulus ; it often 

 grows in great abundance where waste material and rubbish have 

 been dumped. C. atramentariiis grows in clusters often of many 

 individuals; it has a grayish-brown pileus and very wide crowded 

 lamellae. Like the preceding it is more common in autumn. 



C. micaceus is a smaller species and is one of the earliest spring 

 mushrooms. It has a thin pileus and narrow lamellae, the pileus 

 being pale buff or yellowish often with shining particles over the 

 surface and marked with radiating striations. It grows, often in 

 prodigious quantities about the bases of old stumps and is com-
