306. A. clavicularis Fr. Pileus 12 mm. (X in-) and more 

 broad, whitish, light yellowish, becoming fuscous, membrana- 

 ceous, convexo-expanded, striate, dry, without a pellicle, at length 

 depressed at the disc. Stem 5-7.5 cent. (2-3 in.) long, fistulose, 

 tough, even, smooth, not very viscous, whitish, fibrillose at the 

 base. Gills adnate, somewhat decurrent when the pileus is de- 

 pressed, often connected by veins, whitish. 



A remarkable species, related to A. epipterygius, but almost dry ; the stem 

 is viscid only in wet weather. There is a thinner variety with filiform stem. 



In grassy ground in fir woods. Glamis, 1876, &c. Oct.

307. A. pelliculosus Fr. Pileus 1-2.5 cent - (K~i in-) broad, 

 fuscous then grey, membranaceous, campanulate then convex, 

 obtuse, lineato-striate to the middle, with a viscid separable pellicle. 

 Stem curt, 2.5 cent, (i in.) or little more long, fistulose, rigid, 

 tense and straight, somewhat thickened at the apex, smooth, vis- 

 cid, white-livid, becoming fuscous. Gills adnate, alternate, very 

 distant, almost in the form of folds, but wholly simple and ?iot con- 

 nected by veins, joined in a collar behind and decurrent, becoming 

 glaucous. 



The pileus is covered with a viscous separable pellicle like A. epipterygius ; 

 but it is very easily distinguished from that species by the distant, fold-like 

 gills. The gills are much more decurrent than those of A. epipterygius. 

 Growing in troops during very rainy weather. 



On heaths and in heathy woods. Frequent. Sept. -Oct. 



Cinereous. Resembling A. galcriculatus rather than A. epipterygius. M.J.B.

308. A. vulgaris Pers. Pileus 6 mm. (3 lin.) and more broad, 

 fuscous or cinereous, somewhat membranaceous, campanulate 

 then convex, then depressed at the disc, papillate, slightly striate, 

 slightly viscid. Stem 2.5-5 cent. (1-2 in.) long, commonly 2 mm. 

 (i lin.) thick, fistulose, very viscous, cinereous, rooting and white- 

 strigose at the base. Gills at first uncinato-adfixed, then decur- 

 rent, thin, white. 



Gregarious, inodorous, changeable. The pileus is often rufescent when
