On trunks, especially ash. Common. 



Solitary or imbricated. From a globose, or turgid, scaly, blackish Imob, 

 arise one or more stems, whicli are at first slightly compressed, flat, and hol- 

 lowed out above where they are furfuraceous ; gradually the depressed surface 

 expands, and the hymenium is formed beneath the small scales of the upper 

 part of the stem. Pileus, when fully expanded, pallid ochraceous, with 

 scattered, brown, adpressed scales ; spores oblong, white. In vaults and 

 hollow trees it sometimes assumes the form of a Clavaria, but in this case 

 seldom produces a pileus.— il/. /. B. Spores oval, white, very large, "0005 

 X -000025 in.
