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

 there, small, thin, round, uneciual, lacerate, l)ect)niing pallid. 



Upon rotten wood, leaves, etc. 'J'hinner and much more delicate 

 than the preceding; to be distinguished hy its pores scattered in |)atches 

 upon a byssine mycelium with a librillose border. 



8i, P. viRiDANS, B, & Pr. Effused, crustaceous-adnate, thin, at 

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

 tomentose. Pores minute, angular, the dissepiments thin. 



In woods on the lower side of old trunks; rare. 'Vh'\s is n very beau- 

 tiful species. It is at first and when growing all white, Inil in (lr\ ing the 

 pores take on a ])ale green lint, leaving, however, a ])ure 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 ,i8 mm. in diameter. 



82. P. GoRDONiENSis, B. & Br. Effused, membranaceaus, very 

 thin, separable, ])ersistently white; the margin shortly fimbriate. Pores 

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



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

 fleshy, when dry, becoming extremely thin and delicate. The dried s])ec- 

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

 lound in Oreat Britain on I'^ir : it is recorded in the New York Reports by 

 Prof, Chas. H. Peck. 



//. /'J^X^, avgiihir, imcqiial. 



83. P. VAi'ORARius, Pers. Effused, innate; the mj'celium creep- 

 ing in the wood, flocco.se, white. Pores large, angulate, white, becoming 

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



On bark and wood of all kinds; conunon. This is an exlremel) 

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

 ai)out .32 mm. in diameter; their di.ssepiments soon break and the pores 

 become comjionnd and labyrinthiform. In a very ()l)li(|ue position it, at 

 first sight, apjjears a Hydnum, but the teeth are terete and a < lose inspec- 

 tion shows they are ])ores 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. /', papyraccits, Schw., 

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



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

 thin subseparabie white-palish efpiable membrane, the margin somewhat 

 sterile and whitish. Pores (juite large, suljflexuous, shallow, pallid.
