Spores often guttulate, 8-10 by 4.5-5 /a; stipe short, hollow, thick- 

 ened upward, the base subtuberculose, reddish pallid, brown or 

 dark reddish brown, pruinose or slightly pubescent at the base, 1-3 

 cm long, 2 mm thick. 



Upon twigs, bark, wood and other vegetable debris in woods. 

 Rather common. 



M. dichrous is usually found upon bark or wood. The 

 smoky brown color of the pileus in dried plants and the short 

 stipe with its slightly tuberculose base are generally sufficient to 

 characterize this species. 



14 Marasmius foetidus (Sow.) Fr. 



Epicr. Myc. 380. 1838. 



Ann. Rep't N. Y. State Mus., 55 :64s. 1889 (As Marasmius acerinus 

 Peck). 



Pileus submembranous, soft, convex, then explanate, umbilicate, 

 10-20 mm broad, surface subpruinose, fulvo-badius or fox-brown, 

 fading in dry plants ; margin striate-plicate ; at first involute, lax 

 or dropping; context with a strong, disagreeable odor; lamellae 

 annulate-adnexed, not broad, distant, reddish yellow; spores 7-8 

 by 4 /x; stipe pruinose, base minutely floccose, hollow, spadiceous, 

 darker below, 1-2.5 ^^ ^ong, 2 mm thick. 



Upon dead branches and other vegetable debris in woods. 



Rather common, widely distributed in northeastern United States 

 and Canada ; also in Europe. Since the disagreeable odor is not 

 marked except in moist or very fresh plants, collections of M. 

 foetidus are frequently referred to other species.

Bot. Sur. Neb., 4:20 i8g6 (As Marasmius hirtipes Clements). 



Pileus thin, submembranous, convex, 8-13 mm broad ; surface 

 glabrous, finely striate, fulvous-red ; lamellae narrow, adnexed, not 

 crowded, white ; spores 7-8 by 3.5 /x ; stipe equal, long, slender, radi- 

 cate, hollow, brown or alutaceous, white at apex, pruinose to white- 

 tomentose, often with white hairs, 5-13 cm long, i mm thick. 



Upon ground among dead leaves in woods. Common. 



This species varies especially in respect to the long radicating 

 stem which may appear brownish tomentose or brown with minute
