ydlow, or ferruginous, often becoming brown with age; lamellae 

 adnate or decurrent, subdistant, thin, arcuate, pale yellow; spores 

 6-7 by 3-4 fi; stipe tough, elastic, hollow, blackish brown, covered 

 with tawny tomentum which forms minute, meallike patches at the 

 apex and a more or less dense mat at the base, 2-6 cm long, 1-1.5 

 mm thick. 



Upon vegetable mold, often among grass and moss. Not un- 

 common. 



This species has a wide distribution in America as well as in 

 Europe. It seems to have been known in America as M . v e 1 u - 

 t i p e s (Clements, Crypt Form. Colo.. 182) and asM. flammans 

 Cooke (not Berk. 1856) (Rav. Fungi Am. 467). In Europe it seems 

 to be known asM. cauticinalis (Sw.) Fr. or M . cauli- 

 cinalis. (Not M. Agaricus cauticinalis Bull.) 

 Specimens from Romell in Sweden under the name M . cauti- 

 cinalis fulvo-bulbilosus seem to be identical with our 

 New York form. Fries says of M . cauticinalis (Epicr. 

 Myc. 1838) that it is very similar to Omphalia campanella. 

 Peck (N. Y. State Mus. Bui. 67) says, " Similar in color to 

 Omphalia campanella, but differing in its more scattered 

 mode of growth, its longer stem sprinkled with tawny mealy par- 

 ticles, and in its less distinctly umbilicate pileus."

Pileus thin, tough, convex, 6-10 mm broad; surface dry, sub- 

 pruinose, pallid or pale buff ; margin thin, straight, striate in dry 

 plants ; lamellae subarcuate, slightly decurrent, distant, creamy 

 yellow, becoming brownish; spores 8-10 by 4-5 ju, oblong or nar- 

 rowly ellipsoid ; stipe firm, slender, hollow, pallid, subpruinose, 2.5—5 

 cm long, .5-1 mm thick. 



Upon mossy, prostrate tree trunks. Rare. 



38 Marasmius leptopus Peck 



N. Y. State Mus. Bui. 67, p.25. 1903. 



Pileus thin, broadly convex or nearly plane, 6-10 mm broad ; sur- 

 face glabrous, reddish brown ; margin obscurely or rugosely 

 striate ; lamellae adnate, close, thin, narrow, white ; spores oblong 

 or narrowly ellipsoid, 7.5-9' by 3-4 [x ; stipe slender, inserted, hollow, 

 whitish or pallid, glabrous, 2.5-4 cm long, i mm thick.
