when moist, cinereous when dry, densely downy-pubescent, base 
often tawny, 2.5 cm long, 1 mm thick. 
Under coniferous trees. Infrequent. 
Peck (N. Y. State Mus. Bul. 67, p. 25. 1903) sayscreeeeeene 
species is closely related to M. subnudus, (Ell.) Pk. but the 
plant is much smaller, the pileus is usually umbilicate and the stem 
not inserted. The mycelium binds together a mass of dirt and 
needles which adhere to the base of the stem when the plant is 
taken from the ground. In some groups nearly all the pilei are 
campanulate, in others they are nearly plane. This feature is sug- 
gestive of the specific name.’ A comparison of types and descrip- 
tions forces one to the conclusion that M. biformis and M. 
longistriatus are too nearly identical to be regarded as dis- 
tinct species. 
19 Marasmius contrarius Peck 
N. Y. State Mus. Bull 150, p.34: 100. 
Pileus submembranous, tough, broadly convex or nearly plane, 
gregarious, 4-10 mm broad; surface often uneven, glabrous, 
whitish or white with brown center, becoming grayish or sub- 
alutaceous in drying; lamellae adnate or slightly decurrent, sub- 
distant, thin, sometimes branched or irregular, interspaces slightly 
venose, whitish; spores 7-9 by 4-5 p»; stipe slender, white within, 
solid, grayish-tawny, downy, tomentose at base, 2-3 cm long, I-1.5 
mm thick. 
Damp mossy places under spruce and balsam trees. Not common. 
20 Marasmius velutipes Berk. & Curt. 
Ann. Mag. Nat. Hist. III, 4:295. 1859. 
Pileus submembranous, tough, plane or umbilicate, gregarious, 
8-20 mm broad, surface dull chestnut to ochraceous brown, lighter 
or pallescent at the center, smooth; margin at first involute, thin, 
even, smooth, often becoming striate; context thin, tough, white or 
whitish; lamellae white, becoming yellowish, narrow, close, adnate; 
spores 6.5 by 4-4.5 p; stipe reddish brown, covered above with 
whitish tomentum, below with tawny yellow to brown hairs, flexu- 
ous, equal or swollen and spongy below, hollow, often rooting, 3-5 
cm long, I-2 mm thick. 
Among dead leaves of deciduous trees. Rather common.
