84 DECADES OF FUNGI. 
absence of the villous, channelled stem, and in its flabelliform, not per- 
manently spathulate pileus. 
281. 4. (Pleurotus) winguidus, obs niveus, tenerrimus ; pileo 
imbricato flabelliformi submembranacco ; Mudo prorsus nullo ; lamellis 
latiusculis postice rotundatis. Hook. fil., No. 12, cum ic. 
Has. Hot valleys, on dead timber. May. Sikkim Himalaya. 
Inodorous, imbricate, white, extremely delicate.  Pileus 2 inches or 
more broad, flabelliform or suborbicular, entire, fleshy, but very thin, 
smooth, convex. Stem altogether wanting. Gills thin, crowded, 
slightly ventricose, rounded behind. 
Allied to 4. edus, but a very different species. 
282. A. (Pluteus) palumbinus, n. s., pileo convexo umbonato glabro 
erugi carnosulo palumbino; stipite solido albo deorsum leviter incrassato ; 
lamellis ex albo roseis liberis. Hook. fil., No. 72, cum ic. 
Has. On trunks of living trees. Darjeeling, 7,500 feet. Rare. 
Inodorous. Pileus 2 inches across, convex, subhemispherical, 
obtusely umbonate, dry, smooth, even, dove-coloured. Stem about 
2 inches high, 4 of an inch thick, ascending, white, solid, slightly 
thickened downwards, and expanded at the base. Gills rose-coloured, 
at first white, perfectly free. 
Nearly allied to 4. phlebophorus, but quite even and distinctly um- 
bonate. There is no other species with which it can be confounded, 
except 4. Curtisii, Berk., which is at once distinguished by its viscid, 
liver-coloured pileus. 
283. 4. (Pluteus) chrysoprasius, n. s. ; pileo hemisphzerico subconico 
carnosulo pallide prasio glabro ; stipite elongato fistuloso albo ; Mind 
latis alutaceis. Hook. fil., No. 142, cum ic. 
Has. On burnt fir-roots. Base of Tonglo, 2,000 feet. 
Inodorous.  Pileus 1 inch or more across, conico-hemispherical, 
scarcely campanulate, pale leek-green, dry, smooth, even ; flesh thin, 
green like the pileus. Stem 3 inches high, 2 lines thick, white, fistu- 
lose, slightly incrassated downwards. Gills broad, ventricose, rounded 
behind, perfectly free, tan-coloured. 
Of this, unfortunately, no specimens have been preserved, but the 
peculiar characters of the gills are such as to leave no doubt as to its 
proper position. It is, however, very distinct in character from -every 
species of its section. 4. leoninus alone exhibits the yellow tone of 
its gills.
