722. A. appendiculatus Bull. Pileus 5-7.5 cent. (2-3 in.) broad, 

 date-brown then tawny, becoming ochrey-pale when dry, fleshy- 

 membranaceous, thin, ovate then expanded, at length flattened, 

 obtuse, smooth, when dry slightly wrinkled, somewhat sprinkled 

 with atoms. Stem 7.5 cent. (3 in.) long, 4-6 mm. (2-3 lin.) thick, 

 fistulose, equal, smooth, white, pruinate at the apex. Veil fring- 

 ing the margin of the pileus, fugacious, white. Gills somewhat 

 adnate, crowded, arid, white then flesh-coloured, at length fuscous. 



Densely csespitose, very fragile and hygrophanous. Much thinner and 

 more fragile than A. Candolleanus. It may be safely distinguished from species 

 which are nearest to it by the gills being whitish then fuscous-flesh-colour. 



On old stumps. Common. June-Oct. 



Var. lanatus. A curious form, densely woolly when young, traces of the 

 woolly coat remaining at the apex when the pileus is fully expanded. Sibber- 

 toft. B. & B>: 11. 1876. Spores ellipsoid, pellucid, 6-8 x 3-4 mk. K. ; 4x6 

 mk. W.G.S. Name appendicula, a small appendage. From the fragments 

 of the veil hanging on the edge of the pileus. Bull. t. 392. Fr. Monogr. \.

723. A. leucotephrus B. & Br. Pileus 7.5 cent. (3 in.) broad, 

 at the first pallid, somewhat campanulate, wrinkled, then convexo- 

 expanded, whitish. Stem 10 cent. (4 in.) long, f% in. thick, fis- 

 tulose, silky-fibrillose downwards, striate or sulcato-striate at the 

 apex. Ring large, here and there appendiculate. Gills slightly 

 adnate, narrow, 3 mm. (\ l /2 lin.) broad, at the first cinereous- 

 whitish, then grey turning black. 



Caespitose. Clearly different from A. Candolleanus and A. appendiculatus 

 Fr. The pileus is not of a rich brown when young, nor are the gills when old 

 at all brown. 



At base of ash-trees. North Kilworth, 1870. Oct. 



Spores very dark brown-purple, 7x4 mk. B. & Br. Name Xeu/co?, white ; 

 Tempos, ash-coloured. Cinereous-white. B. 6^ Br. n. 1256. Fr. Hym. Eur.

724. A. egenulus B. & Br. Pileus 4 cent. (\ l / 2 in.) broad, 

 watery white, snow-white when dry, hemispherical, expanded, 

 umbonate, but not decidedly rugose or atomate, quite smooth, 

 even, except towards the edge, margin finely striate, appendicu- 

 late. Stem 5 cent. (2 in.) long, 3 mm. (i> lin.) thick, fistulose, 

 attenuated upwards or nearly equal, minutely adpressedly-scaly. 

 Gills adnate, with a tooth, slightly ventricose, moderately distant, 

 purplish umber with a white edge.
