substipitate. The dried specimens have the alutaceous hue of the 

 related species. 



56. P. conchifer, Schw. Whitish. Pileus coriaceous, very thin, 

 concentrically sulcate, glabrous, commonly reniform or flabelliform 

 and substipitate. Pores medium, thin, acute, angulate, dentate, but 

 scarcely lacerate. 



In woods on sticks and fallen branches ; common. A very 

 singular species, and varying remarkably in form and size. It be- 

 gins as a small cup, like a Peziza, furnished with a short, thick stipe, 

 white without, and brown-zonate within; out of the edge of this cup, 

 a very thin reniform or flabelliform pileus is developed, the cup ap- 

 pearing to be consumed in its growth ; the pileus is commonly 

 white or alutaceous, but sometimes the brown-zonate interior of the 

 cup seems to be distributed in fragments over the surface. The 

 pileus is rather small, not often exceeding an inch, sometimes 

 lobed, extremely thin, and marked with faint concentric furrows. 



57. P. bifofmis, Fr. Whitish or alutaceous. Pileus coriaceous, 

 flexible, tough, subzonate, with innate radiating fibers ; the context 

 fibrillose, concolorous. Pores very large, simple, compound, or con- 

 fluent, round, elongated and flexuous ; the dissepiments dentate, 

 then lacerate; the hymenium finally resolved wholly into teeth. 



In woods on old logs ; common. Pileus in its perfect form 2 — 3 

 inches wide and projecting 1 y 2 — 2 inches, often imbricated and 

 laterally confluent. It is often found with the pilei much effused, 

 and more or less deformed, forming a thick, irregular mass with 

 large and much lacerated pores. In the fresh, well-developed pileus, 

 the alternate paler zones are quite conspicuous. The pores are 

 large and irregular from the first, and the dissepiments are dentate. 

 The older plants might be taken for an Irpex. 



VIII. Coriacei. Pileus coriaceous, villous, banded with con- 

 centric zones commonly differently colored. 



58. P. hirsutus, Wulf. Pileus corky-coriaceous, convexo-plane, 

 hirsute with rigid hairs, uniform in color, but zonate with concentric 

 furrows, whitish. Pores round, obtuse, whitish or brownish. 



On wood of all sorts; very common. Pileus 2^/ 2 — 3^ inches 

 in breadth, reniform, often imbricate, marked with conspicuous fur- 

 rows and villous bands of the same color, the margin sometimes
