Fructifications resupinate, effused, fleshy, subcoriaceous 

 or membranaceous; hymenium somewhat undulate-tuber- 

 cular, granular, or even, usually pulverulent with the spores ; 

 cystidia present in some species ; basidia simple ; spores even, 

 ochraceous, sometimes nearly colorless. 



Coniopliora is closely connected on one side with Corticium 

 and Peniophora by such pale-spored species as Coniophora 

 polyporoidea, on another side with the colored-spored sec- 

 P tion of Merulius, and on still another with Gramdinia by sev- 

 ?^ eral species with granular or minute papillae in the 

 hymenium, although the spores of Coniopliora are colored, 

 while those of Grandinia are white. 



Fully developed, mature fructifications of Merulius have 



the hymenial surface more or less reticulate with obtuse folds, 



rP imperfectly porose, or obsoletely toothed, while the departure 



from the even hymenial surface in Coniophora is at the most 



JIl only undulate-tubercular or granular. Since some species
