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. hypococcinus of Berkeley, in Lea's Catalogue, accord- 

 ing to Fries in the Novae Symbolae. 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. cuticularis, 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 the 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. pubescens y Schum. Pileus fleshy-tough, then corky, soft,
