Brownish Mycena     Subgenus

Cortinarius husseyiKey to Gilled Mushrooms     Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.

TricholomaAgaricales     Order
Fruiting body containing fibers (usually in the stalk)

Amanita onustaWhite Spored     Suborder
Spore print "light-colored": white or buff, sometimes tinged with pink or tan. Greenish and (except for the Russulales) yellow spore prints also go here
Stalk fibrous, not fracturing like a piece of chalk

TricholomataceaeTricholomataceae     Family
None of the special features distinguishing the other white-spored genera:
Gills not free, as in the Lepiotas and Amanitas
Basidia not extra-long, as in the Hygrophoraceae
Spores smooth, except for Lentinellus

HygrocybeLignicolous Trich     Subfamily
Growing on trees or dead wood, leaves, or sticks, or organic debris, often in moss

Armillaria tabescensNormal LignoTrich     Tribe
Shaped like a “normal mushroom”
Small and fragile to medium-sized, except for one large, grey-capped species

Small Ligno Trich     Subtribe
Fruiting body small: cap up to 1 1/4" across (and most clearly smaller than that)

Mycena inclinataMycena     Genus
Cap bell-shaped, conical, or either of those with an umbo; margin never incurved; usually some shade of grey or brown, but purplish in one unusually large species.
Stem thin; either very fragile or very tough
Some species have a colored juice that can be squeezed out of the end of the stem
No rhizomorphs

Mycena haematopus


Narrow down your identification:

Mycena alcalina
Odor of bleach (sometimes faint)
Cap up to 3/4" across; blackish at first but soon fading
Gills sometimes aging reddish-brown in spots
In groups on coniferous wood

Mycena corticola
Cap up to 1/4" across; purplish to vinaceous brown at first, fading to pale grey; covered at first with a white powder; deeply plicate
On bark
Stem also powdery at first, with a few white hairs at the base

Mycena galericulataMycena galericulata
Cap some shade of brown or grey, up to 3" across; bell-shaped with inrolled margin when young, spreading out in maturity but remaining darker at the disk
Stalk up to 1/4" thick, brittle, glabrous
On deciduous wood

Mycena inclinataMycena inclinata
Cap up to 1 1/4" across; greyish brown at center, lightening to a whitish margin; conical at first, expanding to umbonate with an uplifted margin; margin scalloped
Stem whitish above, shading to reddish brown below; flecked with tiny white mycelial patches
Cestipose on decaying hardwood stumps, especially oak

Mycena maculataMycena maculata
Cap and gills bruising reddish-brown, or developing reddish-brown spots in age
Basic cap coloration white to greyish brown
