Fruiting body 2-5 cm broad, spatulate to fan-shaped; upper surface translucent, moist, slightly roughened, white to greyish-white when young, pale grey to somewhat brownish in age; hymenial surface on underside, pale grey, consisting of minute conic spines on which the spores are formed; flesh rubbery-gelatinous.
Stipe 5 cm long, up to 1.5 cm broad, lateral, tapering downward, covered with fine hairs, densest at the base; flesh, rubbery-gelatinous.
Spores 5-7 µm, globose, hyaline, smooth. Spores white in deposit.

Pseudohydnum gelatinosum is a jelly fungus with a lower surface that mimics a tooth fungus. The resemblance, however, is superficial. Tooth fungi have fleshy to leathery fruiting bodies, not gelatinous, and none are translucent.
