 Fructification effused, adnate, often suborbicular, tliin, dry, 

 tomentose, hypoelinoid, drying Sudan-bro^\^l ; 

 structure in section about 300ju, tbick, composed of 

 loosely interwoven, even-walled byj)bae 4V>-5/a 

 in diameter, nodose-septate, concolorous through 

 the whole fructification with the hymenium; no 

 H ferrif ineus cystidia ; basidia 4-spored; spores subglobose, 

 Hypha, spore coiicolorous witli the fructificatiou, echinulate, 

 ^ ' body of spore about 7-8jLt in diameter. 



Fructifications 2-4 cm. in diameter or 3-6 cm. long, about 

 2-3 cm. 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, 

 common 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.

 Sweden: Femsjo, L. Romell, 225, 227.
