HYjrENOMYOETES. 



Srih-genus DEKMINUS. 



10 B. SCABEE. Bull. 



This and the preceding maj'" be distinguished from most other 

 British species, especially when young, bj' the white tubes, 

 and the substance, which is ronarkably solid and heavy 

 From B. edulis, B. scaber differs in having a viscid pileus, frcr 

 tubes, a squarrose stem, and, according to Fries, dull lerru 

 ginous spores. Under beech trees, Rainhill. 



Genus XVII. POLYPORUS. Mich. 



Suh-genus MESOPUS. 



11 P. LENT0S. Berkeley. 



Stem J — 1 high. ^ — J diam. Pileus 1—3 broad. Toughly 

 fleshy ; pileus sub-depressed, reddish-brown, slightly scaly, 

 when young ; stem at first central, at length more or less ex- 

 centric; pores large from the first, somewhat radiately dis- 

 posed, angular, very decurrent ; in a growing state the dis- 

 sepiments are thick, and have a central paler trama. Spores 

 oblong, white. '0000. Copiously given otf in drying. This 

 species was gathered by the Eev. M. J. Berkeley on living 

 ulex EuropKus in 1832. I do not find it noticed by any other 

 author, unless it be the Polyporus coronalus of Eostkovius 

 figured in Sturm's Dcutschlands Flora. It may probably 

 belong to the genus Favolus of Fries. Found on living ulex 

 Europreus at Eastham, Stourton, and the warren, New Brighton. 



13. P. LEPTOCEPHALUS. Jacq. 



Stem 5 high. J diam. Pileus 1 broad. Between fleshy and 

 coriaceous, fawn-coloured, nearly plane; pores minute, whitish. 

 Found on a tree in Cheshire by I. Byerley, Esq. 



13 P. PERENNIS. L. 



Stem 1 high. J diam. Pileus 2 — 3 broad. Coriaceous, thin, 

 infundibuliform, cinnamon, zoned ; stem thickened downwards, 

 velvety. Eastham Wood, August, 1856.

 fleshy, fan-shaded, or expanso-spathulate, ochraceous with broad, 

 dark-brown scales ; pores at first minute, then large, angular, 

 pale. Connnou on decayed trees and stumps.
