Lentinellus     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


Lentinellus ursinusLentinoLignoTrich     Subtribe
All mushrooms with serrated gills go here
If the stem is central and well-developed, then the fruiting body (even the cap) is large and extremely tough


Lentinellus     Genus     Karsten




Lentinellus ursinus

Diagnosis


Narrow down your identification:


Lentinellus angustifolius
Like Lentinellus ursinus, except
Cap up to 3" across
Gills narrow, crowded

Lentinellus cochleatusLentinellus cochleatus
Stem marginal (occasionally central); furrowed; fusing at the base with other stems in the cluster
Cap up to 2" across; dark reddish brown to light pinkish tan; semi-circular at first, becoming heart-shaped as it extends back around the stem; lobed in maturity, margin wavy
Densely cestipose on deciduous stumps and buried wood

Lentinellus omphalodesLentinellus omphalodes
Cap up to 2" across; beize darkening to brown; hygrophanous
Stalk usually furrowed; more or less concolorous with cap
Taste acrid

Lentinellus ursinusLentinellus ursinus
Cap sessile, broadly attached to substrate; up to 5" wide, 2" deep; fan- or kidney-shaped; yellow-brown to reddish brown; covered with velvety or fuzzy dark-brown hairs, at least near the attachment
Gills broad, subdistant

Lentinellus vulpinus
Cap stipitate, up to 4 1/2" wide, fan- or kidney-shaped; pale pinkish or pinkish-brown with some darker brown streaks; covered with velvety or fuzzy white fur; margin inrolled at first
Stalk marginal, lateral; fuzzy and colored like cap
