The Mycologic Floi a of the Miami Valley, O. i 7 



On a hard, dry Ash log. Pilei more or less imbricated, and 

 laterally confluent, projecting half an inch in my specimens, the 

 folds frequently interrupted behind, and appearing like coarse 

 papillae, when dry suffused with a dull tawny bloom. 



2. P. MERisMoiDES, Fr. Effused, flesh-colored, then livid, 

 villous and white on the under side, the border orange, strigose. 

 Wrinkles simple, straight, crowded. 



On stum])s and trunks commonly incrusting mosses, but also 

 investing the rough bark, common. In incrusting the mosses out 

 growths proceed from the surface as well as the margin. Effused 

 in patches sometimes several inches in extent. 



3. P. RADIATA, Fr. Subrotund, equal, glabrous on both 

 sides, fleshy-red, the border radiate-dentate. Folds straight, seri- 

 ately radiating. 



On smooth bark and wood; common. Though originating in 

 circular patches with the wrinkles radiating from the center, these 

 patches soon become confluent often to the extent of a foot or more. 

 This species is thinner than the preceding, is lighter colored, and 

 is not villous next to the matrix. F. cinnabarina, Schw. does not 

 appear to differ otherwise than in the color. 



Genus V. — Grandinia, Fr. 



Hymenium amphigenous, contiguous, waxy, papillose-warty 

 or rather granulose. Granules globose or hemispheric, entire, ob- 

 tuse, close, regular, glabrous, persistent. 



I. G. MuciDA, Fr, Waxymucid, effused, subinnate, reddish- 

 yellow; the border determinate, somewhat radiating. Hymenium 

 contiguous; granules close, rather large, unequal, hemispheric, 

 soft. 



On wood and bark of Beech, Elm, etc.; not rare. In an early 

 stage subrotund, but soon widely confluent. 



Genus VI, — Odontia, Fr. 



Hymenium composed of interwoven fibers, v^hich coalesce into 

 papillose or aculeate warts, cristate-multifid or penicillate at the 

 apex. 



I. O. FIMBRIATA, Pcrs. Effuscd, membranaceous, seceding, 

 pallid, traversed by root-like fibers ; the border fibrillose-fimbriate. 

 Warts minute, in the form of granules, multified at the the apex, 

 rufescent.
