LEUCOSPORI. 123 



On fir-trunks among the Hypnum cupressiforme . Aboyne, &c. Mycena. 

 Aug.-Sept. 



Under a high magnifying power the pileus (especially the edge) and stem 

 appear clothed with minute glandular particles similar to those which colour 

 the edge of the gills. B. &> Br. Name margo, margin. Diminutive. From 

 the edge of the gills. Pcrs. Syn. p. 309. ? Fr. Hym. Eur. p. 131. B. & Br.

252. A. aurantio-marginatus Fr. Pileus 2.5 cent, (i in) or a 

 little more broad, olivaceous-fuscous, becoming pale when older, 

 fleshy at the disc, campanulate then convex, obtuse or obsoletely 

 umbonate, even, smooth, margin straight, slightly striate only at 

 the margin when moist and unfolded. Stem 2.5-4 cent. (i-iX i n -) 

 long, 6-8 mm. (3-4 lin.) thick at the base, 2-4 mm. (1-2 lin.) at 

 the apex, firm, fistulose, inflated ventricose and zoned with yellow 

 strigose villous down at the base (but scarcely rooted), even, 

 smooth, livid-pale. Gills very ventricose, hence very attenuato- 

 adnexed, at first sight appearing free, crowded, connected by veins, 

 becoming green-livid, the orange edge toothed or rather flocculoso- 

 pencilled. 



In its slightly fleshy, campanulate then convex pileus, like A. pelianthinus, 

 it inclines towards the Collybice ; otherwise very much allied to A. elegans, 

 perhaps a variety but larger and more fleshy. 



In silver-fir wood. Perth, 1875. Nov. 



Stem very brittle. Smell strong. It is admirably figured in the ' Flora 

 Danica,' and has a peculiar aspect which separates it from other species, look- 

 ing more like a Marasmius than a Mycena. B. 6 s Br. Name aurantius, 

 orange ; margo, margin. From the edge of the gills. Fr. Monogr. i. p. 197.

253. A. elegans Pers. 12 mm. (% in.) and more broad, be- 

 coming light yellow-fuscous or light yellow-livid, opaque not 

 hygrophanous, membranaceous, campanulate, more or less um- 

 bonate, striate, smooth. Stem about 5 cent. (2 in.) long, 2 mm. 

 (i lin.) thick, fistulose, rigid-tense and straight, equal, livid, 

 floccoso-fibrillose at the base. Gills adnate, decurrent with a 

 tooth, linear, slightly distant, distinct, commonly livid, bluish- 

 grey at the sides, the edge always darker, saffron-yellow, entire 

 not manifestly toothed. 



The gills are changeable in colour, varying whitish, becoming yellow, &c., 

 always, however, with the darker edge. Odour weak, of fennel, or even obsolete. 

 Kalchbrenner gathered a singular variety called hyperborea (Enum. ii. n. 

 1039), with smoky or black gills, somewhat cinnabar at the edge. 



In woods, chiefly pine. Frequent. Aug.-Nov.
