Entoloma luteum is like the drab, dreary little brother of Entoloma quadratum and Entoloma murrayi, both of which are brightly colored. Unlike its siblings, Entoloma luteum is a dull brownish yellow--and its cap is not as acutely conic. It is found in hardwood and mixed hardwood-conifer forests, often near moss, in eastern North America. Under the microscope it features cube-shaped spores and long cheilocystidia.
Ecology: Saprobic; growing alone, scattered, or in little clusters under hardwoods or mixed hardwoods and conifers; summer and fall; probably fairly widely distributed east of the Great Plains. The illustrated collection is from northern Michigan.
Cap: 1-3 cm; rounded-conical or bell-shaped; dry; bald, or finely silky over the center; dull brownish yellow, occasionally with a greenish tinge; fading to dull yellowish; the margin becoming finely lined.
Gills: Narrowly attached to the stem; nearly distant; at first whitish or yellowish, becoming pink with maturity.
Stem: 3.5-7 cm long; 2-4 mm thick; more or less equal; dry; bald or very finely hairy; whitish near the apex, elsewhere colored like the cap; basal mycelium white.
Flesh: Thin; fragile; yellowish.
Odor and Taste: Odor not distinctive; taste mild or slightly bitter.
Spore Print: Pink.
Microscopic Features: Spores 8-11 µ; cuboid; hyaline. Pleurocystidia absent. Cheilocystidia cylindric with rounded or clavate apices; 50-100 x 10-15 µ. Pileipellis a cutis with frequently uplifted terminal elements; golden in 10% ammonia; pigment granular and intracellular. Clamp connections present.
Nolanea lutea is a synonym.
