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. 
Соторһоға 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 вес- 
tion of Merulius, and on still another with Grandinia by sev- 
eral species with granular or minute papillae in the 
hymenium, although the spores of Coniophora 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, 
imperfectly porose, or obsoletely toothed, while the departure 
from the even hymenial surface in Coniophora is at the most 
only undulate-tubercular or granular. Since some species
