nearly a foot in diameter. The color of the specimens varies 

 greatly with the age ; they are at first, and when perfectly fresh, of 

 a gorgeous crimson-orange ; then the surface of the pileus grows 

 paler through orange to alutaceous ; and the hymenium grows 

 darker through brownish crimson to dark brown ; the substance 

 varies to reddish and pale wood-color, and is remarkably zonate. 

 This is the P. Jiypococcimis of Berkeley, in Lea's Catalogue, accord- 

 ing to Fries in the Novae Symbolic. Schweinitz seems to have 

 found it but once, and his specimens had evidently lost their brill- 

 iancy ; while! Mr. Berkeley's description is based upon the notes 

 and careful observations of Mr. Lea. This is certainly one of the 

 most magnificent of fungi, both in size and color. 



35. P. cuticiilaris , Bull. Pileus thin, spongy, fleshy, then dry, 

 applanate, hirsute and tomentose, rusty brown, becoming blackish ; 

 within loosely parallel-fibrous ; the margin fibrous-fimbriate, in- 

 curved. Pores minute, long, pallid, then ferruginous. 



In woods on old trunks; common. Pileus 2 — 4 inches in diame- 

 ter and rather thin. More or less imbricated and concrescent, ob- 

 soletely zonate, unequal and somewhat triangular, inflexed when 

 dry; the tomentum strigose or velvety. Pores in the fresh speci- 

 mens cinereous, pruinose, glittering when turned in the light. 

 Spores very abundant, Indian yellow, .0056 mm. in length. 



b. Context White. 



36. P. galactinus^ Berk. White. Pileus simple or subimbricate, 

 spongy-fleshy, soft, becoming hardened, strigose-tomentose, 

 zonate within ; the margin incurved. Pores minute, round, entire. 



In woods on rotten logs ; common. Pileus 2 — 4 inches in 

 width, somewhat pulvinate, thick, and sometimes gibbous behind, 

 at first fleshy, soft and fragile, but drying quite hard, the margin 

 curving inward ; the color is commonly a milky white, but some- 

 times this is modified by sordid or smoky tints. The pores in the 

 fresh plant are extremely minute, with thick dissepiments, and the 

 hymenium has a silky luster ; in ihi; dried specimens they appear 

 larger, thin, and somewhat angular, but always entire. There is 

 little if any difference between this and P. undulatus, Schw. 



37. P. piibescens, Schum. Pilf.ais fleshy-tough, then corky, soft.
