moisture, and in growing on wood; the small species of 

 CantJiareUus decay at maturity, and grow on mosses or leaves. 



LENZITES. Fries, (figs. 8, 9, p. 301.) 



Pileus corky, coriaceous, horizontal, dimidiate, sessile and 

 tittached behind ; gills coriaceous, firm, unequal, simple or 

 branched, radiating from the point of attachment, sometimes 

 anastomosing and forming irregular pores, margin acute or 

 obtuse ; spores white.

Most nearly allied to the genus Daedalea, but the hyme- 

 nium is more of the Agaricoid than the Polyporoid type. In 

 the Polyporeae the hymenium is porous from the first, then 

 frequently, as in Daedalea quercina many of the dissepiments 

 become torn, and thus the hymenium presents a labyrinthi- 

 form appearance, hence it is towards the margin of the adult 

 pileus that pores are observed, as in Daedalea, Cyclomyces, 

 &c. In the Agaricinae the hymenium at first consists of 

 radiating gills or lamellae, which afterwards in some species 

 become joined by transverse ribs that form irregular pores 

 most abundant at the base, as in species of Pleiirotus, Paxillus, 

 and many other tough genera. In texture and substance, 

 Lenzites agrees with the Polyporeae, in the same way that 

 Favolus, belonging to the Polyporeae, agrees with the Agari- 

 cinae. (Fries.) 



Coriaceous, perennial or persistent ; allied to Daedalea and 

 Trametes. Gills coriaceous, firm, sometimes simple and 

 unequal, at others branches and anatomosing behind to form 

 pores ; trama floccose, like the pileus ; margin of gills acute 

 in some species, obtuse in others. All the species grow on 

 wood, and in the European forms, dimidiate and sessile.

Lenzites betulina. Fr. 

 Pileus 3-4 in. long, 1-2 in. broad, more or less reniform or 

 flabellate, horizontal, attached behind by an expanded base, 

 flesh 2-3 lines thick behind, thin towards the margin, corky, 

 coriaceous, firm, pallid, slightly zoned, tinged brownish, 

 becoming pale, margin same colour; gills thin, lJ-2 lines
