and corrugated, smooth, 2-3 cm. across ; gills distant, adnate, 

 rather broad, connected by prominent ribs ; spores elliptical, 

 5 X 3/a; stem up to 1 cm. long, slender, furfuraceous. 



On dead wood. Wairarapa, Northern Island, New Zea- 

 land. Himalayas. 



Distinguished by the membranaceous substance, pure- 

 white colour, and the prominent ribs on the inside of the 

 pileus connecting the gills. Tough. Type specimen ex- 

 amined.

Smell strong and very unpleasant ; pileus convex, then 

 plane, the centre often depressed, reddish-bay, pale when dry, 

 1-5-2-ocm. across when expanded ; flesh thm, soft and pliant, 

 membranaceous from the margin half-way up and coarsely 

 striate ; gills at first slightly adnexed, but becoming free 

 during the expansion of the pileus, connected by veins, ventri- 

 cose, at first crowded then distant, white with just a suspicion 

 of pink; spores elliptical, 8 x 4-5 ju. ; stem 3-5 cm. long, 

 2 mm. thick, equal, slightly wavy or fiexuous, tough, rufous 

 or rufous -brown or sometimes purple -violet, naked, but 

 entirely covered with delicate white down when dry, base 

 narrowed and rooting.

 New Zealand. Australia, Europe. 



Gregarious. Agreeing with Marasviius fcetidics and M. 

 perforans in the strong foetid smell. The last two named, how- 

 ever, differ from the present in having the stem minutely but 

 distinctly velvety. 



115. Marasmius vaillantii, Fries, Epicr., p. 330; Sacc, 

 Syll. v., no. 2072. 



Pileus thin, pliant, at first convex, soon flattened and more 

 or less depressed at the disc, marked with radiating ridges, 

 whitish, l'5-2-5 cm. across when expanded; gills adnate, but 

 from their triangular form appearing somewhat decurrent, 

 broad, distant, distinct, simple, white ; spores elliptical, 

 10x6 /a; stem about 2-5 cm. long, thickened upwards, 

 glabrous, bay, shining, apex paler, base blackish, naked, 

 penetrating the substance upon which it is growing. 



On dead wood, fallen twigs, leaves, &c. Dannevirke, New 

 Zealand. Europe, United States. 



Inodorous. Small, tough, dry. Marasmius impudicus 

 differs in the purplish stem becoming covered with white 

 velvety down when dry.
