Fructification effused, adnate, often suborbicular, thin, dry, 
tomentose, hypochnoid, drying Sudan-brown; 
structure in section about 3005 thick, composed of 
loosely interwoven, even-walled hyphae 414-5y 
in diameter, nodose-septate, concolorous through 
the whole fructification with the hymenium; no 
Н. e eystidia; basidia 4-spored; spores subglobose, 
Hypha, spore concolorous with the fructification, echinulate, 
gen body of spore about 7-8а in diameter. 
Fruetifieations 2-4 em. in diameter or 3-6 em. long, about 
2-9 em. broad. 
Under side decaying limbs and logs of various frondose 
species. Canada and New Brunswick to Georgia and west- 
ward to Michigan. July to October. Occasional. 
This species is well marked by its very constant color, 
соттоп to both hyphae and spores, and its occurrence in ad- 
nate, small, and very thin, hypochnoid areas of the form and 
dimensions given. American collections agree closely in 
above respects with the European specimens received from 
Bresadola which he has noted as surely H. ferrugineus.
