52. P. cimiabanmis, Fr. Pileus corky, pubescent becoming 

 glabrous, scarcely zonate, rugulosc, cinnabar-red, expallent. Por,es 

 round, medium, entire, of a deeper red than the pileus. 



On trunks of all sorts, especially Cherry; common. Pileus 2 — 4 

 inches in breadth, convex above and plane beneath. The younger 

 plants and the growing margin are pubescent, the older portion 

 becomes glabrous, and is wrinkled and pitted. It is recognized at 

 once by its elegant color. It is given as a Trametes in the second 

 edition of the Epicrisis. 



b. Context White. 



53. P. Jiifllliusculus, Berk. Whitish. Pileus corky, thin, radiate- 

 ly wrinkled, zonate, velvety-strigose ; the margin often lobed ; the 

 context floccose, white. Pores medium, subrotund ; then thin, 

 acute and lacerate. 



In woods on old trunks; common. Pileus i )^ — 3 inches in 

 breadth, usually much imbricated, and usually effuso-reflexed ; the 

 zones of soft strigae are sometimes a little deeper colored. The 

 dried plants are very light, and of an isabelline or alutaceous hue. 



54. P. fibula, Fr. Whitish. Pileus coriaceous, soft, tenacious, 

 velvety-hirsute, azonate, often radiate-rugose ; the margin entire, 

 acute; the context floccose, white. Pores rather small, round, 

 acute, at length lacerate, becoming yellowish. 



On fallen branches ; rare. Pileus an inch or two in breadth, im- 

 bricate and variously concrescent, rather thick. Its substance is sofj 

 and light when dry, like the preceding, but it differs in its uniform 

 and more conspicuous pubescence not arranged in zones. 



55 P. virgincus, Schw. White. Pileus coriaceous, thin, tough, 

 zonate, glabrous, radiately wrinkled, tuberculose ; the margin thin, 

 undulate ; the context floccose-fibrous, white. Pores medium, 

 round, entire ; becoming thin, angular, acute. 



In woods (jii old trunks ; not common. The pilei have a peculiar 

 habit of growing orbicular or with a helicoid or spirally imbricate 

 arrangement, being attached by the center underneath ; they vary 

 in form, however, to reniform and dimidiate, and are sometimes 

 substipitate. The dried specimens have the alutaceous hue of the 

 related species. 



56. P. conchifer, Schw. Whitish. Pileus coriaceous, very thin, 

 concentrically sulcate, glabrous. c(^ninionly reniform or flabelliform
