Laccaria longipes is a long-stemmed, sphagnum-loving species of Laccaria known from the Great Lakes region. It is usually found in the vicinity of spruces, tamarack, or alders. Like other Laccaria species, it has a white spore print and thick gills with a somewhat waxy texture. Aside from the long stem (measuring 7-15 cm long or more) and habitat in Midwestern sphagnum bogs, features that distinguish Laccaria longipes from other, similar Laccarias are primarily microscopic (see details below).
Cap: 1-8 cm; convex, becoming flat or with a shallow central depression; the margin usually lined; finely hairy; orangish brown, fading with age.
Gills: Attached to the stem; distant or nearly so; pinkish flesh color.
Stem: 7-15 cm long; up to about 1 cm thick; equal or with a slightly enlarged base; hairy; colored like the cap; with whitish basal mycelium.
Flesh: Thin; pinkish flesh colored.
Odor and Taste: Taste not distinctive or slightly bitter; odor not distinctive.
Spore Print: White.
Chemical Reactions: KOH on cap surface negative.
Microscopic Features: Spores 7-8 x 6-8 µ; globose or subglobose; ornamented with spines mostly about 1 µ long, with bases < 1 µ wide; inamyloid. Basidia 4-spored. Cheilocystidia absent. Pileipellis a cutis of elements 5-10 µ wide, occasionally aggregated into upright bundles; terminal cells subclavate to cylindric.
