Upper surface:
up to 0.8cm high, with cap and stem, cap 0.4-1cm in diameter, shallow cup-shaped or flattened disc-shaped, often collapses on substrate when old; yellow to pallid yellow or lemon when fresh, drying pallid yellow or orange-yellow

Microscopic:
spores (16)17.5-22(24) x 4.5-5.5(6) microns, "strongly curved-cylindrical to allantoid, thin-walled with thin septa, tinted, apiculate", becoming 5-7(9)-septate at maturity, germination by colorless, elliptic to short-cylindric conidia or by germ tubes; probasidia 42-60(70) x 3.5-4.5 microns, cylindric-subclavate, with basal clamp connections, becoming bifurcate; hymenium "confined to interior of cup or superior surface of disc, composed of basidia and occasionally simple, cylindrical dikaryophyses"; internal hyphae "thin-walled, smooth or roughened, clamp connections present"; cortex and stem "covered by a palisade of vesicular cells with thick, gelatinous walls and reduced lumina, varying in shape from ovate to obpyriform, often elongated apically into a smooth, obtuse beak, basally smooth, to 60 x 20 microns"
