26 GUIDE TO CRYPTOGAMS. 



Coprinus. Spores black. 



4 is Lamellce thickish, edge blunt. 



Cantharellus. Lamellae fleshy and waxy, dichotomously 

 branched, decurrent on the stalk. 



3 b. Sporocarp leathery or corky, persistent. 

 9 a. ¥ ileus borne on a central stalk, which is cartilaginous 

 or homy, differing in texture from thepileus. 



Marasmius. Lamellae membranaceous, dry, with entire acute 

 edges. 



9 b. Pileus stemless or with a lateral, or rarely a central 

 stalk, which is of the same texture as the pileus. 



Panus. Pileus toughish, coriaceous-fleshy ; lamellae membra- 

 naceous-leathery, with acute entire edges. 



Trogia. Pileus thin and softish ; lamellae wrinkle-like, with 

 crisped edges. 



Lenzites. Pileus corky or leather}', sessile ; lamellae 

 leathery, simple or branched, often anastomosing freely near 

 the hinder end, edges entire. 



Lentinus. Pileus fleshy-coriaceous ; lamellae with serrate or 

 dentate edges. 



Schizophyllum. Pileus coriaceous, lamellae with the edges 

 split lengthwise and the halves revolute. 



2 b. Hymenium lining the cavities of tubes or i?i the 

 variously shaped holloics formed by anastomosing 

 ridges. 



Pistulina. Sporocarp tongue-shaped or spatulate, sessile or 

 stalked, fleshy ; hymenium in cylindrical tubes, free from one 

 another on the under surface of the pileus. 



Boletus. Sporocarp consisting of a pileus borne on a central 

 stalk, fleshy, putrescent ; hymenium in tubes joined together on 

 the under side of the pileus forming a layer which may be easily 

 peeled off. 



Polyporus. Sporocarp mostly dimidiate, sessile or with a 

 lateral stalk, sometimes with a central one, tough, cork} r , leath- 

 ery or woody, persistent ; hymenium in long narrow, round or 

 angular tubes joined together forming a layer.
