IV. APUS. 



Pileus sessile, adnate, dimidiate ; lignatile. 



A. ANODERMEI. Pileus at first more or less fleshy and 

 watery or juicy, without a distinct cuticle. 



I. Carnosi. Pileus cheesy, at first watery-soft, fragile, floccu- 

 lose ; pores white. 



23. P. lacteiis, Fr. White. Pileus fleshy-fibrous, fragile, tri- 

 quetrous, pubescent, azonate ; the margin inflexed, acute. Pores 

 thin, acute, dentate, at length labyrinthiform and lacerate. 



In woods, on trunks, especially of beech. Commonly small and 

 thin, about an inch in width, but sometimes transversely elongated ; 

 steep and gibbous behind, becoming at length smooth and unequal. 



24. P. fragilis, Fr, Whitish, brown spotted to the touch. 

 Pileus fleshy-fibrous, fragile, piano-depressed and reniform, rugose, 

 convex beneath. Pores thin, long and flexuous, intricate. 



In woods, on very rotten wood ; rare. Pileus 2 — 3 inches in 

 breadth, projecting an inch or more, and about an inch in thick- 

 ness. The specimens so referred were at first white and very 

 fragile ; in handling and drying they have become brown and brittle. 



25. P. ccFshis, Schrad. White, here and there with a bluish 

 tinge. Pileus fleshy, soft, tenacious, unequal, silky. Pores small, 

 unequal, long and flexuous, dentate, lacerate. 



Iji woods, on sticks; rare. Pileus ^ — 1 5^ inches broad and 

 long, simple or subimbricate, sometimes sub-stipitate. The color 

 assumed by my specimens is a bluish-gray. The pores are rather 

 small and become toothed and lacerate. 



26. P. delectans. Peck. White, becoming yellowish. Pileus 

 fleshy-fibrous, firm, simple or subimbricate, azonate, subtomentose. 

 Pores large, unequal, at first subrotund and obtuse, then thin, an- 

 gular and dentate. (Plate i.) 



In woods, on fallen trunks; common. Pileus two to four inches 

 in breadth, with a projection of one to two inches, or, confluently, 

 several inches in width. The stratum of pores is about half the 

 thickness of the pileus. 



27. P. destructor, Schrad. Pileus watery-fleshy, effuso-reflexed, 

 fragile, rugose, subundulate, brownish-whitish, zonate within. Pores 

 long, roundish, dentate or lacerate, white.
