306 FUNGUS-FLOEA. 



Dimidiate, lateral, corky-coriaceous, hard, convex then 

 flattened, orbicular, or frequently elongated, 1-3 in. broad, 

 zoned, strigosely tomentose, at length squamulose ; tawny- 

 yellow when young (and persistent at the margin), bay 

 when adult, becoming blackish when old. Sometimes 

 resupinate, forming orbicular plates. Flesh tawny. Gills 

 spreading from the base, very rigid and firm, branched, 

 more or less anastomosing and resembling Baedalea, 1-2 

 lines broad, yellowish when growing, umber, when old, 

 margin entire or minutely toothed. (Fries.) 



Lenzites abietina. Fr. 



Pileus 1,^—5 in. long, 1 in. or a little more broad, hori- 

 zontal, thin effuso-reflexed, covered with dark umber down, 

 becoming almost glabrous and hoary ; gills decurrent when 

 effused behind, simple, imequal, glaucous from a dense 

 bloom ; spores elliptical, smooth, 7-8 x 4 /a.

 360; Cke., Illustr., pi. 1146b. 



On fir trunks, deals, &o. 



Always longitudinally extended, efiiiso-reflexed, and some- 

 times resupinate ; coriaceous, thin and soft, zoneless, covered 

 with umber-coloured down, then becoming almost glabrous, 

 hoary. I have seen it extending for a foot in length, but 

 narrow, about |^ in. broad. Gills decurrent on the effused 

 base, distant, simple, unequal, not anastomosing, frequently 

 interrupted or torn into teeth, glaucous from the dense 

 bloom. (Fries.) 



XEEOTUS. Fries, (fig. 16, p. 301.) 



Pileus dry, membranaceous, tough; gills coriaceous, re- 

 sembling broad folds, dichotomous, margin quite entire, 

 obtuse, attached to the central or excentric stem; spores 

 white. 



Xerotus, Fries, Epicr., p. 48 ; Cke., Hdbk., p. 359. 



The membranaceous pileus, and coriaceous, dichotomous 

 gills having the obtuse margin quite entire, readily dis- 

 tinguish the present from all other genera. It is almost 

 a coriaceous-membranaceous Cantharellus, but in the last- 

 named genus the gills are much broader. (Fries.)
