222 HRITISII KUNdl 



X. degcner. — Cap about i in. across, thin and tough, somewhat 

 funnel-shaped, but the edge flattish, greyish bay and striate when 

 moist, somewhat zoned, about i in. across ; gills few, decurrent, 

 chstant. some forked, greyish white ; stem up to i in. long, brown 

 with \vhite down. 



\'ery tough, cap plane, liecoming funnrl-sliaped, flocculose and 

 zoned when dry. 



On gra\-elly ground, etc. Very rare. 



Lenzites 



Cap corky and coriaceous, growing horizontally, sessile, and 

 attached l)y a narrowed portion behind ; gills coriaceous, tough, 

 simple or branched, sometimes joined to form irregular pores here 

 and there, radiating from the point of attachment ; spores white. 



Differing from the sessile, horizontal kinds of agarics, as Pleit- 

 rotiis, in the thicker, coriaceous, somewhat elastic gills. Allied in 

 texture to Dcedalca, but the gill idea is more marked than in that 

 genus. Coriaceous, perennial, or persistent, that is, not decaying 

 at once as in agarics. 



L. betitlina. — Cap more or less kidney-shaped or fan-shaped, 

 horizontal, attached by an expanded base, corky, ]:>allid or tinged 

 brownish, slightly zoned, 1-3 in. broad ; gills thin, forked, and 

 joining on to each other, straight, dingy white. 



Cap downy, usually indistinctly zoned. 



On trunks and stumps, especially birch. 



L. fiaccida (PL XXX, fig. 5). — Cap horizontal, semicircular or 

 more or less fan-shaped, narrowed behind to the point of attachment, 

 hairy, zoned, tinged grey or brown, 1-2 in. broad ; gills broad, 

 crowded, straight, branched, whitish. 



Differs from L. hdulina in the coarsely hairy, thin tlesh of the 

 caji, and the thick, straight gills. 



On trunks and stumps. 



L. sepiaria. — Cap horizontal, hard, zoned, hairy, wrinkled, bay or 

 umber, thick ; gills thick, branched, and growing into each other, 

 yellowish. 



Hard, orbicular or elongated, 1-3 in. broad, becoming dark brown 

 or blackish when old. 



On fir trunks, stumps, posts, etc. 



L. abidina. — Cap horizontal, thin, spreading on the matrix 

 with a free-spreading portion, at first with dark umber down, then 

 almost smooth and hoary, i|-5 in. long, about i in. broad ; gills 

 decurrent when effused on the matrix, simple, unequal, glaucous 

 from a dense white bloom, due to the mass of spores. 



Sometimes resupinate, always more or less effused on the matrix, 

 sometimes spreading for a foot or more in length, with a free edge, 

 |— I in. broad. 



On fir trunks, posts, rails, boards, etc.
