North American species of Mycena.

to campanulate pileus, the spores, and the bulbous base of the stipe,
as Karsten pointed out, separate the species from M. vulgaris. No
reddish spots were noticed in my material, but, since both collections
were made during comparatively dry weather, it does not seem advisable to place much emphasis upon the absence of these spots.
The spore size as obtained from dried specimens is apt to intergrade
more with that of M. vulgaris than is that of material from deposits. Because of the possibility of intergradations of M. militaris
with M. vulgaris Karsten's species should be critically studied some
season when material is abundant in order to evaluate its distinctive
characters more fully.

Pileus 8-15 mm. broad, usually obtuse to convex when young,
sometimes with a sharp conic umbo, becoming broadly convex and
with or without a subacute or obtuse umbo, finally plane, the disc
nearly always depressed in age, margin straight or only slightly incurved at first, soon spreading and often wavy in age, surface glabrous
and very viscid when moist, pellicle completely separable, conspicuously translucent-striate to the disc, striations dark, sulcate when
faded, color "fuscous" more or less over the disc and "smoke gray"
near the margin, gradually fading to "drab" over the center and
finally sordid smoke gray or yellowish gray over all, not hygrophanous;
flesh very thin but pliant, pallid grayish, taste slightly disagreeable,
odor slight when flesh is crushed, subnauseous to subraphanoid;
lamellae bluntly adnate, soon arcuate, and in age distinctly decurrent,
close, 13-17 reach the stipe, one or two tiers of lamellulae, sometimes
forking near the base, moderately broad, up to 2 mm., whitish to pale
