290 BRITISH FUNGI 



F. inaiirata. — Whole fungus sulphur-yellow. Cap up to i in. 

 across ; gills adnate, with a decurrent tooth ; stem alout i in, 

 long, incurved. 



On willow trunks. • 



F. apicrea. — Cap 1.^-3 in. across, convex, then becoming almost 

 plane, thin, smooth, moist, dingy orange, disc darker, edge often 

 splitting ; gills adnate, crowded, shining ferruginous ; stem 2-3 in. 

 long, not rooting, pallid, fibrillose, rusty downwards, as are also 

 the fibrils, hollow. 



Very similar to J^. alnicola, but the colour of the gills is almost 

 unchangeable, flesh hygrophanous, and sweet smell distinguishes it. 



On rotten trunks. Rather tufted. 



F. carnosa. — Tufted in habit. Cap soon expanded, very fleshy 

 and broadly gibbous, edge remaining more or less incurved for 

 some time, even, smooth, dull tawny orange, flesh yellowish, com- 

 pact, f-i| in. across, flesh | in. or more thick at the disc, thin at 

 the extreme edge ; gills somewhat crowded, thin, slightly decur- 

 rent, rust-coloured, powdered with the spores ; stem about equal, 

 solid, fibrous, colour of the cap, 2-3 in. long. 



Remarkable for the very fleshy cap, the thickness of which 

 appears to be out of proportion to the rest of the fungus. Entirely 

 dull tawny orange. Spores elUptical, smooth, brown, 7x5 /i. 

 This species has not previously been described ; it was found by 

 Mr. A. Clarke at the Y.N.U. Fungus Foray at Castle Howard, 

 1909.

 narrowed upwards, down}', then silky, rather striate, whitish with 

 silky down, but tawny orange when the down disappears, ring 

 present as a white annular zone near the apex of the stem. 



On stumps and on the ground, growing on roots, fragments of 

 wood, etc. 



F. sapinea. — Cap 1-3 in. across, fleshy, compact, hemispherical, 

 then expanded, very obtuse, slightly flocculoso-squamulose, then 

 usually cracked into minute scales, dry, tawny orange, edge paler ;
