The Mycologic Flora of the Miami Valley, Ohio. 95 



side becoming cinereous or olivaceous; the folds or veins become 

 quite conspicuous. 



2. H. ALRiFORMis, Schw. Substipitatc, concave, flexuous, 

 thin, venose, glauco fuscous; somewhat pubescent underneath. 

 Stipe lateral short, twisted, sulcate-lacunose. Spores oblong, 

 curved, .014-016 mm. in length. 



On trunks and branches of Walnut; common. Two to 3 inches 

 in length and breadth. The hymenium does not grow black as in 

 the preceding species, and the pubescent underside has a tawny or 

 brownish hue. 



Clcnus VI. — (luEi'iNiA, Fr. 



Fungi cartilaginous-gelatinous, free, various in form, substipitate. 

 Hymenium on one side only; sporophores linear, long-forked, 

 bisporous; spore.s septate, curved. 



1. G. SPATHULAKiA, Schw. Nearly erect, stipitate, .spathulate, 

 the stipe and upper side cinereous-pubescent. Hymenium plicate, 

 orange-yellow; spores curved, apiculate, three-septate, .010-. 012 

 mm. in length. 



On old wood; common. Growing csespitosely and rooting in 

 the cracks of the wood, often in a linear series, nearly an inch in 

 height. The delicate nerves or folds of the hymenium are decurrent 

 upon the stipe. 



2. G. ELEGANS, B. (S: C. Nearly erect, stipitate. Pileus orbi- 

 cular or fan-shaped, tawny as well as the stipe. Hymenium 

 plicate, brownish-amber colored; spores curved, apiculate, three- 

 septate, .015-. 01 8 mm. in length. 



On wood of Elm; not common. Growing ccespitosely, often 

 lobed and confluent, nearly an inch in height. The fine pube- 

 scence is tawny or rufcscent ; the well-developed hymenium is 

 plicate with decurrent folds and becomes blackish with age. 



3. G. PEZizA, Till. Gupular, nearly sessile; glabrous both 

 sides, yellow, adnate behind. Stipe slender. Hymenium superior; 

 spores tiiree-septate, .010-. 01 2 mm. long. 



On old wood; rare. Cup shaped, concave, 3-5 mm. broad. 

 It- looks like a small Pe/.iza, and is not likely to be found except 

 when < ollectiiig these small fungi.
