Omphalina     Genus

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)

Omphalina ericetorumOmphalinoids     SemiTribe
Mature fruiting body with an omphalos, never bell-shaped or conical. Never even flat except when very young.
Usually more colorful than the other choices
Often growing in or among a lichen

Microscropic Characters


Originally "Omphalia"

Narrow down your identification:

Omphalina ectypoides
Cap 1- 2 1/2" across, various shades of yellow to brown, at first with minute dark scales or hairs
Not striate; margin wavy but not scalloped

Omphalina ericetorumOmphalina ericetorum
Cap up to 1 1/2" across, usually less than an inch; brown fading to yellow; in age, cap pleated and margin scalloped by the gills
Growing with a lichen which is so inconspicuous that it may be obscured by the moss that it also often grows with
