byssine, fibrillose-radiating. Pores in the center or collected here and 

 there, small, thin, round, unequal, lacerate, becoming pallid. 



Upon rotten wood, leaves, etc. Thinner and much more delicate 

 than the preceding ; to be distinguished by its pores scattered in patches 

 upon a byssine mycelium with a fibrillose border. 



81. P. viridans, B. & Br. Effused, crustaceous-adnate, thin, at 

 first white, afterward, when dry, pale green ; the margin pulverulent- 

 tomentose. Pores minute, angular, the dissepiments thin. 



In woods on the lower side of old trunks; rare. This is a very beau- 

 tiful species. It is at first and when growing all white, but in drying the 

 pores take on a pale green tint, leaving, however, a pure white sterile 

 border, elegantly puberulent and fimbriate. It is at first a little humid 

 and seems to be furnished with a subcoriaceous subiculum, which is 

 closely adnate to the wood. The thin dissepiments of the pores are in no 

 wise toothed or torn. The pores measure about .18 mm. in diameter. 



82. P. Gordon 1 ensis, B. & Br. Effused, membranaceaus, very 

 thin, separable, persistently white ; the margin shortly fimbriate. Pores 

 minute, unequal, angulate ; the dissepiments very thin, fi mbriate-denate. 



In woods on old trunks of Elm ; rare. At first apparently somewhat 

 fleshy, when dry, becoming extremely thin and delicate. The dried spec- 

 imens scarcely show the elegantly fringed teeth of the pores. It was first 

 found in Great Britain on Fir; it is recorded in the New York Reports by 

 Prof. Chas. H. Peck. 



//. large t angular, unequal. 



83. P. vaporarius, Pers. Effused, innate; the mycelium creep- 

 ing in the wood, floccose, white. Pores large, angulate, white, becoming 

 pallid, crowded together into a contiguous, firm, persistent stratum. 



On bark and wood of all kinds ; common. This is an extremely 

 variable species in its appearance. The pores at first are angular and 

 about .32 mm. in diameter; their dissepiments soon break and the pores 

 become compound and labyrinthiform. In a very oblique position it, at 

 first sight, appears a Hydnum, but the teeth are terete and a close inspec- 

 tion shows they are pores split on one side. There is no border, but a 

 thin white mycelium creeps close in the surface of the wood and bark. 

 The white color soon becomes stained and rusty. P. papyraceus, Schw., 

 growing on dead grapevines, is said not to be different. 



84. P. tenuis, Schw. Long and longitudinally effused, forming a 

 thin subseparable white-palish equable membrane, the margin somewhat 

 sterile and whitish. Pores quite large, subflexuous, shallow, pallid.
