DERMTNI. 241 



Gregarious. In the form which appears in summer the scales on the pileus Inocybc. 

 are squarrose, and the gills darker ; in that of autumn, the scales are adpressed 

 and the gills paler. Batt. t. 18. A. 



On the ground in mixed wood. Pass of Killiecrankie, 1877. 

 Aug. 



Pileus convex, umbonate, umber, clothed with adpressed fibres, the centre 

 breaking up into areolate patches, about 8-12 mm. ( l A-% in.) across; stem 

 2.5 cent, (i in.) or more high, 2 mm. (i lin.) thick, of the same colour as the 

 pileus, scaly below, tomentose above ; gills clay- coloured, ventricose, margin 

 paler, waved, adnate, with a strong decurrent tooth ; spores even ; flesh white ; 

 taste at first pleasant. In one specimen the gills are just as figured by Per- 

 soon. Though he gives in his specific characters " stipite nudo" the stem is 

 represented in the figure as scaly. B. 6* Br. The above description of the 

 specimens which I submitted to Berkeley was written on account of their de- 

 parture from the type as figured by Persoon. Name dulcis, sweet ; amarus, 

 bitter. Alb. & Schw. n. 489. Fr. Monogr. i. p. 337. Hym. Eur. p. 228.

531. A. plumosus Bolt. Pileus 2.5-4 cent. (1-1% in.) broad, 

 mouse-colour, slightly fleshy, somewhat membranaceous at the 

 circumference, convex then plane, more rarely obtusely umbonate, 

 at the first squarrose with erect fasciculate flocci, fibrilloso-silky at 

 the margin. Stem 5-7.5 cent. (2-3 in.) even 10 cent. (4 in.) long, 

 2-4 mm. (1-2 lin.) thick, stuffed when young, then hollow, equal 

 or attenuated at the base, flexuous, everywhere floccoso-scaly,fulig- 

 inous-mouse-colour, of the same colour at the base, naked (not 

 pruinose) at the apex. Gills somewhat adnate, scarcely crowded, 

 narrow, not very ventricose, pallid mouse-colour, the edge which 

 is of the same colour quite entire. 



Odour weak, almost pleasant. It is easily distinguished from A. lacerus by 

 the flesh both of the pileus and stem never being reddish. 



In moist pine woods. Rare. Aug.
