Summary: Subgenus Phlegmacium. Features include 1) a lubricous, pale ocher cap with a margin that is inrolled for a long time, 2) thick, white flesh, 3) crowded, whitish young gills, 4) a pale whitish stem with a brownish marginate bulb, 5) a whitish veil, 6) a mild odor and taste, 7) growth in coniferous forests, and 8) microscopic characters. The description is derived from Breitenbach(5) except where noted.
Cap: 4-6cm across, hemispheric when young, later convex to flat, "margin inrolled for a long time"; light yellow-ocher to reddish ocher ["pale cap" is also referred to as a characteristic feature]; "smooth, dull when dry, lubricous and shiny when moist", (Breitenbach), light ocher, loam or cardboard-brown, possibly with slight rust tone (Moser)
Flesh: thick; white
Gills: broadly attached, narrow, 85-127 reaching stem, 1-3 subgills between neighboring gills; whitish becoming gray-ocher to gray-brown; "edges slightly crenate"
Stem: 3.5-5(6)cm x 1.5-2.2cm, cylindric, solid, fragile, marginate bulb up to 3.5cm wide; stem "cream-colored and white-fibrillose", bulb ocher-brown to reddish brown, "especially the margin of the bulb"
Veil: margin joined to bulb of stem "by a white, filamentous cortina when young"
Taste: mild, insipid
Microscopic spores: spores 9.1-11.5 x 5.8-6.8 microns, amygdaliform [almond-shaped] to citriform [lemon-shaped], moderately verrucose; reddish ocher; basidia 4-spored, 26-32 x 8-9.5 microns, clavate, with basal clamp connection; no pleurocystidia, marginal cells 15-35 x 3.5-5 microns, cylindric; septa with clamp connections, (Breitenbach), spores 9-10(11) x 6-6.5 microns, (Moser)
Notes: DNA sequencing indicates its presence in BC (Harrower(1)). It is also found in Europe including Switzerland, (Breitenbach(5)).
