512 CLASS BASIDIOMYCETEAE 



or papillar hymenium; basidiospores usually colored, rough- walled to 

 echinulate. Tomentella 



(Hypochnus of some authors) 

 Hymenophore membranous or coriaceous, not reflexed or saucer-shaped: 

 basidia mostly forming a continuous smooth or papillose hymenium. 

 Basidiospores white or rarely bright-colored. 



Cystidia lacking. Corticium 



Cystidia present in hymenium or in subhy menial tissues or both. 



Peniophora 

 Brown stellate organs pi-esent in subhymenial tissue. 



Asterostroma 

 Hymenium interrupted by sterile pegs or projections. 



EpitJiele 

 Basidiospores ochraceous, ferruginous, or fuscous, smooth. 

 Cystidia lacking. Coniophora 



With cystidia. Coniophorella 



Hymenophore leathery or corky, saucer-shaped, or at least upturned at the 

 edges; basidiospores pale-colored, usually large; cystidia of various 

 types. Aleurodiscits 



Resembling the foregoing but with groups of dendrophyses (feather-like 

 cystidia) forming projections above the hymenium. 



Dendrothele 

 Saucer or cup-shaped, more or less gelatinous-fleshy. Cytidia 

 Hymenophore adhering closely to the substratum; antler-like cystidia forming 

 a felty layer above the basidia. Vararia 



(Asterostromella) 

 Hymenophore of three layers, resupinate or more often reflexed-effuse or attached 

 laterally. 

 Leathery, without cystidia. Stereum 



Leathery, sometimes almost woody or corky, variable in shape; with stiff, 

 brown, pointed setae extending from the hymenium. 



Hymenochaete 

 Hymenophore upright, often stalked, simple or branched or funnel-shaped, or 

 pendent cup-shaped or separate tubes. 

 Hymenium Hning the inner surface of pendent cups or tubes. 

 Sessile or stalked cups; separate. CypheUa 



Tube-like arising together, but not united, from a common subiculum. 



Solenia 

 Hymenium lining the outer or lower surface of funnels or flattened lobes. 

 Leathery; spores mostly l^i'own and roughened. 



Hymenium almost smooth or warty. Thelephora 



Hymenium with woody ribs; tropical, Cladoderris 



Other uncommon genera. Skepperia, Hypolyssus 



Fleshy, much branched, forming a round, cabbage-like structure; spores 

 hyaline, smooth. Spnrassis 



Key to the Genera of Family Cantharellaceae 



(After Smith and Morse, 1947) 



Fruit body typically fleshy and (centrally stipitate or stipe eccentric, but well- 

 developed (or whole fruit body funnel-shaped and stipe not distinct). 

 Hymenium smooth or nearly so. Craterellus
