The Mycologic Flora of tJie Miami Valley, Ohio. 197 



663. We have retained the name given in the Elenchus of Fries 

 I., p. 189, which we suppose to be the original one in Syn. Car., 

 No. 1061. 



Genus V. — Hyinienoch.^te, Lev. 



Coriaceous, dry. Hymenium even, beset witli minute rigid 

 setae. 



The hymenium with a common lens is velvety or pubescent, 

 but with a moderate magnifying power of the compound microscope, 

 the minute usually colored bristles are brought out distinctly to 

 view. 



I. A PUS. Pikiis cffuso-reflexed. 



1. H. RUBIGINOSA, Schrad. Coriaceous-rigid. Pileus effuso- 

 reflexed, subfasciate, velvety, reddish ; afterward becoming glab- 

 rous and brown ; the intermediate stratum tawny-ferruginous, 

 Hymenium ferruginous, velvety wMth minute bristles. 



On hard wood of oak, beech, etc.; common. Pileus 1-2 

 inches in breadth and projecting 4- to f of an inch. The single pilei 

 are often shell-form but frequently many are confluent and im- 

 bricate. It is thin rigid and brittle. 



2. H. ciNERASCENS, Schw. Coriaceous. Pileus effuso- 

 reflexed, strigose-hirsute, subzonate, whitish or cinereous. Hy- 

 menium cinerepus, sometimes with a smoky or purplish tinge, be- 

 coming pallid or whitish, velvety with minute pellucid bristles. 



On trunks of Mulberry and Ehn ; not uncommon. Often oc- 

 curring as small resupinate patches with a narrow reflexed margin, 

 but sometimes extensively effused for several feet with pilei re- 

 reflexed half an incn or more. It is sometimes found with pale 

 yellowish zones. I'he delicate pellucid bristles appear to be true 

 setae and not metuloids of Dr. Cooke's genus Pcniophora. 



3. H. cuRTisii, Berk. Coriaceous, thin. Pileus effused 

 and narrowly reflexed, pallid, glabrate ; the margin ferruginous. 

 Hymenium papillate, rugose, becoming rimose, ferruginous, the 

 minute bristles few and scattered. 



On branches and twigs of Oak ; common. Appearing first 

 as small orbicular peltate patches with a paler subbyssoid margin, 

 these then become confluent and effused sometimes for several feel 

 in length, with a very narrow reflexed margin on either edge. The 

 growing specimens are a bright ferruginous, becoming dull with 

 age.
