Entoloma lividoalbum: The Ultimate Mushroom Guide
About The Entoloma lividoalbum Mushroom
Entoloma lividoalbum is characterized by a Tricholoma-like stature, a nearly glabrous, dingy-brown cap often with a lighter disc, a translucent-striate margin, solid stipe, and a faint farinaceous odor and taste, the odor most apparent when the cap tissue is crushed.
Identifying a species often requires careful study of the cap, stipe, odors if present, and in some cases microscopic features.
Entoloma lividoalbum was originally described (Kühner & Romagnesi 1954) from Europe; our North American versions may represent as-yet-unnamed species.
Entoloma lividoalbum Identification
Saprobic; growing alone, scattered, or gregariously under hardwoods (including quaking aspen and coast live oak); summer and fall, or overwinter in coastal California; fairly widely distributed west of the Great Plains; also known from temperate Europe.
5–7 cm; conico-convex to bell-shaped or convex at first, becoming broadly convex, broadly bell-shaped, or nearly flat; greasy when fresh; bald; dark grayish brown when young, quickly fading to yellow-brown or grayish tan; the margin not lined or only faintly lined at maturity.
Narrowly attached to the stem; close or nearly distant; at first white, becoming pink with maturity.
5–8 cm long; 1–2 cm thick; more or less equal; dry; bald but finely lined longitudinally; white.
Thin; fragile; white.
Odor and Taste
Mealy or, in forma inodoratum, not distinctive.
Spores 7–10 x 6–8 µm; mostly 5- and 6-sided; heterodiametric; smooth; hyaline in KOH. Basidia mostly 4-sterigmate. Hymenial cystidia not found. Pileipellis a cutis with intracellular brownish pigment; elements 5–7.5 µm wide, smooth, hyaline in KOH; terminal cells cylindric with rounded or subacute apices. Clamp connections are present.
Entoloma lividoalbum Look-Alikes
Has a similar stature and a greyish-brown glabrous cap, but typically grows in clusters. When in doubt it can be distinguished by a white spore print.
Though normally distinctive with a lilac-colored sporocarp, can be nearly brown in age or with weathering, sometimes even mimicking the often wavy cap margin of Entoloma lividoalbum. The pinkish-brown angular spores of Entoloma lividoalbum serve to distinguish it from Clitocybe nuda which has pinkish-buff, elliptical spores.
Common under oaks, but with a dark-brown cap, lighter towards a striate margin, the cap context <8 mm thick at the stipe, and a momentary nitrous odor that becomes farinaceous.
A slender species, with a relatively thin cap <7 mm thick near the stipe, the margin translucent-striate, sometimes halfway to the disc, a stipe that is often hollow at maturity, and a weak farinaceous odor.
Has a dark-brown cap that may become dingy orange-brown at the disc, thus appearing two-toned, the cap context >10 mm thick near the stipe, the gills greyish when young.
Found under conifers, with a yellowish-tan cap and marginal striations reaching halfway to the disc, the cap context <7mm thick near the stipe, and a strong nitrous odor when fresh. For more information on these and other species.
