Key to the genera of the Clavariaceae. 



Ai) Plants fleshy, or fleshy-fibrous, not very small. 



SPARASSIS. Plants branched, branches foliaceous, much flattened. 



ACURTIS. Plants fibrous-fleshy, divided into fibrous clavate branches, spores 

 mealy. (This genus is now regarded by some as an abnormal form of 

 Lentinus tigrinus. XI, 139). 



CLAVARIA. Plants fleshy, branched or simple, branches typically terete, some 

 simple forms clavate. 



Ramaria Holmsk. Branched, branches above attenuate. , (Sacc. 692). 



Syncoryne Fr. Subsimple, cespitose or fasiculate at base. (Sacc. 717). 



Holecoryne Fr. Subsimple, at the base distinct. (Sacc. 722). 

 A*) Plants gelatinous-cartilaginous. 



CALOCERA. Viscid when moist, drying horny, simple or branched, hymenium 

 tremelloid. (Placed by Massee in the Dacryomycetaceae, because of the 

 forked basidia). 



A») Plants leathery or nearly so. 

 a) Hymenium setulose, tomentose, or hairy. 



LACHNOCLADIUM. Branched, with sterile setae or a sterile tomentum. 



HIRSUTELLA. Plants clavariaeform, simple or branched, straight, rigid ; hairy 

 from the very long sterigmata on the basidia. (Here belongs according to 

 Sacc, XI, 140, Pterula setosa Pk). 

 aa) Hymenium smooth, i. e., not setulose, etc. 



PTERULA. Plants leathery, cartilaginous, dry, terete or compressed, single or 



branched. 

 A*) Plants waxy or somewhat waxy ; usually quite small, 

 a) Clavula or head solid or stuffed, 



TYPHULA. Simple or clavate with fihform stipe; often arising from a sclerotium. 



PISTILLARIA. Sessile or attenuated into a stem-like base, becoming horny and 

 rigid when dry, linear, subclavate or subcapitate, rarely arising from a. 

 sclerotium. 

 Eu-Pistillaria. Clavula ovate-oblong or very terete, everywhere fertile 



(Sacc. 752). 

 Ceratella Pat. Clavula elongate, apex acute, sterile. (Sacc. 758). 

 Pistillina Quel. Clavula hemispherical, lenticular or subglobose. (Sacc. 759) 

 aa) Clavula hollow or vesiculose. 



PHYSALACRIA. Somewhat rigid, stem slender, distinct. 



Tretnellineac. 



Dacryomycetaceae : Basidia bifurcate, each long sterigma bearing a single 

 basidiospore ; or basidia long, slender and one-spored.
