ascending, smooth, but " fibrilloso-striate," variegated with white Pleurotus. 

 and flesh-colour. Gills rounded behind, joined in a collar, not 

 adnate to the stem itself, broad, crowded, rufescent, paler than 

 the pileus. 



Csespitose. A very remarkable species, with the flesh variegated like that 

 of Fistulina.

365. A. craspedius Fr. — Pileus as much as 7.5-12.5 cent. (3-5 

 in.) broad, brick-colotir, more or less excentric, sometimes some- 

 what lateral, but marginate behind, fleshy, thin and at length 

 almost membranaceous towards the margin, flaccid, plane, de- 

 pressed behind when very excentric, even, smooth, somewhat 

 moist, but without a separable pellicle j margin at first involute, 

 then evolute, elegantly crenato-lobed and fimbriate ; flesh thin, 

 watery, white when dry. Stem in some 2.5 cent, (i in.), in others 

 as much as 7.5 cent. (3 in.) long and then twisted or compressed, 

 1-2.5 cent. (X"~i in.) thick, solid, firm, elastic, internally spongy, 

 very unequal, sometimes thickened at the base, sometimes equal, 

 pallid, commonly smooth or slightly villous at the base. Gills 

 wliolly adnate, not sinuate, obtuse behind, very thin, crowded and 

 narrow, at length lacerated, shining white. 



With autumn rain the pileus becomes pale-tan, sometimes cinereous. 

 Csespitose. It connects in a remarkable manner species which are otherwise 

 very different, on the one hand A. ulmarius and A. palmatus, and on the 

 other A. fiinbriatus and A. lignatilis; it has the robust stem and habit of the 

 former, but the thin pileus and very narrow very crowded gills of the latter. 



On trunks and rotten wood. Ratton, Eastbourne, 1852. Sept.
