Entoloma lividoalbum

[Basidiomycetes > Agaricales > Entolomataceae > Entoloma . . . ]

by Michael Kuo

This western Entoloma is fond of hardwoods, and can be recognized by its fairly large stature, the yellow-brown cap that does not develop a prominently lined margin, the finely lined white stem, and the mealy odor. Microscopic features (see below) will help confirm identification.

Edibility is not known for Entoloma lividoalbum, and it would make a dangerous experiment.

Description:

Ecology: Saprobic; growing alone, scattered, or gregariously under hardwoods (occasionally reported under conifers); summer and fall (and over winter in California); fairly widely distributed west of the Great Plains.

Cap: 5-9 cm; convex becoming broadly convex or broadly bell-shaped; dry to greasy; smooth; yellow-brown, fading with age; the margin not lined or only faintly lined at maturity.

Gills: Attached to the stem; nearly distant; at first white, becoming pink with maturity.

Stem: 7-20 cm long; 1-2.5 cm thick; more or less equal; dry; smooth but finely lined longitudinally; white, often discoloring and bruising brownish near the base.

Flesh: Thin; fragile; white.

Odor and Taste: Mealy.

Chemical Reactions: KOH on cap surface negative.

Spore Print: Pink.

Microscopic Features: Spores 7-12 x 5-12 µ; mostly 5- and 6-sided; angular; inamyloid. Cystidia absent. Pileipellis a cutis. Clamp connections present.

Rhodophyllus lividoalbus is a synonym.
