Entoloma murrayi is a distinctive little mushroom. Typically found in swamps or wet woods east of the Rocky Mountains, it has a conical, yellow cap with a prominent, extended point and a silky texture; a yellow stem; and a pink spore print. Under the microscope, the species features cube-shaped spores. Compare Entoloma murrayi with Entoloma luteum, which is similar but usually more drab and always less pointy--and with Entoloma quadratum, which is pointy, but orange.
Ecology: Saprobic; growing alone, scattered, or gregariously under hardwoods or conifers in swamps and wet woods; summer and fall; eastern North America, southward to Central America.
Cap: 1-3 cm; conical or bell-shaped, with a dramatically pointed center; silky; bright to dull yellow, with the uplifted center often becoming white; dry or somewhat sticky when fresh; the margin becoming lined and/or tattered with age.
Gills: Narrowly attached to the stem; close or nearly distant; whitish to pale yellow at first, becoming pink as the spores mature; short-gills frequent.
Stem: 3-6 cm long; 2-3 mm thick; equal; hollow; fragile; dry; bald; yellow; with white mycelium at the base.
Flesh: Thin; fragile; colored like the cap.
Odor and Taste: Not distinctive, or slightly radishlike to foul.
Chemical Reactions: KOH negative on cap surface.
Spore Print: Pink.
Microscopic Features: Spores 6-10 µ; cuboid; four-sided in profile; smooth; hyaline. Pleurocystidia absent. Lamellar edge sterile. Cheilocystidia scattered and often clustered; basidiole-like or longer and cylindric-clavate. Pileipellis an ixocutis of non-pigmented elements. Clamp connections absent or very rare.
