Summary:
Features include 1) resupinate growth on hardwoods, 2) a tightly attached, waxy fruitbody colored creamish to pale ochraceous, the surface smooth to tuberculate, the margin white, finely fibrillose in young specimens, 3) a fruity odor when fresh, 4) spores that are nearly round or broadly elliptic, inamyloid, and thick-walled, with low rounded warts, 5) basidia that are suburniform with a stem, 6) sulfo-positive gloeocystidia that are very numerous (young ones projecting), cylindric or fusiform, and obtuse or acute, with oil droplets of various sizes, and 7) a monomitic hyphal system, the hyphae with clamp connections.

Microscopic:
SPORES (6)7.5-10 x (5)7-8 microns, nearly round or broadly elliptic, with low rounded warts, inamyloid, cyanophilic, thick-walled, with prominent apiculus, usually with one droplet; BASIDIA 4-spored (normally), 50-75 x 6-9 microns, at first narrowly clavate, then cylindric, "somewhat constricted in a suburniform way and often sinuous, basally tapering to a stalk-like hyphal part", with basal clamp connection, protoplasm grainy and with some oil droplets of different sizes; CYSTIDIA (gloeocystidia, sulfocystidia) very numerous, cylindric or fusiform, obtuse or acute, vertical like a palisade, thin-walled, protoplasm filled with oil droplets of different sizes, positive reaction to sulfovanillin, turning the oil violet, oil droplets also visible in cotton blue but dissolved in Melzer''s reagent, some adventitious septa without clamp connections seen, "apices of gloeocystidia often projecting as far as mature basidia, in young specimens even longer"; HYPHAE monomitic, 2-4 microns wide, richly branched, thin-walled, with clamp connections, "densely united especially in the thickened subhymenium where they are vertically arranged between the gloeocystidia, in the subiculum easier to distinguish but still in a close texture", "subicular layer reaching 100 microns in thickness with more or less horizontal hyphae, growing hyphal ends often seen among the basidia", (Eriksson)

Notes:
Gloeohypochnicium analogum has been found in BC, ID, ON, AZ, MD, ME, NC, and WV, (Ginns), as well as France, Norway, Poland, Sweden, and the USSR, (Eriksson).
