LEUCOSPORI. 125 



It has many features in common with A. strobilinus. It is smaller, thinner, Mycena. 

 softer, and paler. Both species preserve their habit, stature, and colours always 

 unchanged, A. rosellus becoming pale only when old. Laxly gregarious. 



In woods, among fir-leaves. Uncommon. Sept.-Oct.

II. ADONIDE^:. Colour pure, bright, &>c. 



257. A. purus Pers. Pileus 1-7.5 cent - (K~3 in -) broad, rose- 

 colour, &c., slightly fleshy at the disc, campanulate then ex- 

 panded, at length rather plane, breast-shaped with an obtuse even 

 umbo, smooth, slightly striate at the margin. Stem 5-10 cent. 

 (2-4 in.) long, 2-4 mm. (1-2 lin.) and more thick, fistulose, rigid, 

 somewhat tough, equal or attenuated upwards when larger, even, 

 smooth, villoso-fibrillose at the base, of the same colour as the 

 pileus. Gills adnate, but very broad, hence they appear broadly 

 emarginate or sinuate, ventricose, elegantly connected by a network 

 of veins, pallid or whitish, the edge, which is of the same colour, 

 quite entire. 



The colour of the pileus (which often becomes pale) and stem varies, rose, 

 purple, lilac, bluish-grey, white. The pileus varies membranaceous, for the 

 most part striate. The margin is straight when young, so that it is certainly 

 a species of Mycena. Odour weak of radish. One remarkable form is wholly 

 milk-white, with the pileus often yellowish ; another is quite snow-white, with 

 ventricose stem. At first sight it is difficult to detect the affinity of these with 

 the common rose-coloured or violet form. 



In woods, meadows, &c. Very common. July-Nov. 



The taste as well as the smell is that of radish. There are occasionally con- 

 centric grooves on the pileus. Spores 6-10x4 mk. B.; 5x3 mk. W.G.S.

258. A. pseudo-purus Cke. Pileus scarcely exceeding 2.5 

 cent, (i in.) broad, rosy then pale, rather fleshy, campanulate then 

 convex, expanded, obtusely umbonate, smooth, margin obscurely 

 striate. Stem 5-7.5 cent. (2-3 in.) long, slender, hollow, rigid, 

 straight, even, naked, at first rosy-white, becoming brown when 

 dry. Gills adnate, whitish. 



The stem in A. purus does not change colour. Spores in A. purus shorter 

 and ovoid, whilst in this species they are regularly elliptical. Allied to A. 

 zephirus.
