d. yellowish. 



72. P. vitellinus, Schw. Widely effused, loosely adnate, thick, 

 uneven, soft and fleshy, vitelline, with a byssine margin. Pores very 

 large, elevated, unequal, thin, angular. 



On very rotten wood. A soft and fleshy fungus of unequal thickness 

 and large unequal pores. The color is very elegant and persists even in 

 drying ; the egg-yellow pervades the whole mass. The long pores vary 

 from round to angular and even sinuous. Strings of yellow mycelium 

 penetrate the rotten wood beneath. 



73. P. x antholoma, Schw. Widely effused, closely adnate, even, 

 smooth, dry : the border rather broad, velvety, yellowish. Pores minute, 

 unequal, subrotund, obtuse, pale yellowish. 



Common in woods. Effused often to the extent of many inches or 

 even several feet on the underside of sticks or smaller branches lying 

 somewhat up from the ground and keeping it dry. The border is some- 

 times "elegantly luteous" and therefore of a deeper yellow than the pores 

 but this is not always the case. The pores at first are pale, maturing into 

 a rich cream-color; they are mostly roundish but vary to oblong and sub- 

 sinuous; the dissepiments are thick and obtuse; they average .16 mm. in 

 diameter. 



74. P. bomuvcinus, Fr. Effused, silky-membranaceous, loosely 

 adherent, sordid yellowish, with a cobwebby-velvety border. Pores 

 ample, angulate. 



On an old rotten log of Sugar Maple; rare. A very distinct and 

 singular species. It first appears as subrotund byssine spots, soon forming 

 in the center a porose hymenium, these then become confluent into a soft 

 rather thick membrane. The pores originate as little pits sunk in the 

 mycelium out of which they are wholly developed, being at first subrotund, 

 then growing firmer they become angular and sometimes flexuous. The 

 dried specimens have taken on a brownish hue and the dissepiments are 

 very thin, dentate and lacerate. P. subiculosiis, Peck, seems not much 

 different from the primordial state of this species. 



e. cinereous. 



75. P. cinereus, Schw. Widely effused, adnate, firm; the border 

 narrow, thin white-fimbriate. Pores small, unequal, subrotund, obtuse, 

 cinereous. 



In woods on the lower side of old logs ; common. The whole of a 

 uniform ashen hue except the minute whitish fringe of the border. The
