yellow, or ferruginous, often becoming brown with age; lamellae 
adnate or decurrent, subdistant, thin, arcuate, pale yellow; spores 
6-7 by 3-4 p; 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, I-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. velu- 
tipes (Clements, Crypt Form. Colo. 182) andas M. flammans 
Cooke (not Berk. 1856) (Rav. Fungi Am. 467). In Europe it seems 
to be known as M. cauticinalis (Sw.) Fr. or M. cauli- 
cinalis. (Not M. Agaricis cauticinalis see 
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 (pier: 
Myc. 1838) that it is very similar to Omphaliacampanella. 
Peck (N. Y. State Mus. Bul. 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.”

N. Y. State Mus. Bul. 139, p.25. 1910. 
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 p, 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. Bul. 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-G by 3-4 p; stipe slender, inserted, hollow, 
whitish or pallid, glabrous, 2.5-4 cm long, 1 mm thick.
