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.
Rhodophyllus luteus and Inocephalus luteus are synonyms.
Thanks to Fluff Berger for collecting, documenting, and preserving Entoloma luteum for study; her collection is deposited in The Herbarium of Michael Kuo.
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 and described collections are from Michigan and Pennsylvania.
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 brownish pink with maturity.
Flesh: Thin; fragile; yellowish.
Odor: Not distinctive.
Spore Print: Pink.
Microscopic Features: Spores 8–12 µm; cuboid; smooth; walls about 0.5 µm thick; hyaline to yellowish, often with one large oil droplet, in KOH. Basidia 4-sterigmate. Pleurocystidia not found. Cheilocystidia 50–100+ x 10–15 µm; cylindric with rounded or clavate apices. Pileipellis a cutis with frequently uplifted terminal elements; golden in 10% ammonia; pigment granular and intracellular. Clamp connections present.
