Summary: Dacryopinax spathularia produces yellow to orange, tough, gelatinous fruitbodies that become flattened toward the cap which is typically petal-shaped, spatula-shaped, or palmate, and often deeply divided. The fruitbodies grow tufted, gregarious, or in lines, on wood.
Microscopic: spores (7)8-10.5(11.5) x 3.5-4(4.5) microns, slightly curved-cylindric, thin-walled with thin septa, tinted, apiculate, becoming 1-septate at maturity, germination by colorless spherical to nearly spherical conidia, to 2.5 microns in diameter, or by germ tubes; probasidia 20-35 x 3.5-5 microns, cylindric-subclavate, with basal septa, becoming bifurcate; hymenium "smooth or longitudinally folded, typically unilateral and becoming directed toward the substratum", occasionally all the way round, composed of basidia; cortex and stem "tomentose, covered with simple or sparingly branched, smooth, thick-walled, septate hairs, cylindrical, straight or tortuous, hyaline or faintly tinted, 4-6 microns diam.", internal hyphae "thin-walled, becoming thick-walled toward the cortex, smooth or roughened, septate, clamp connections absent", (McNabb), spores 7-10.5 x 3.5-4.5 microns, allantoid, 1-2-cellular, (Raitviir), spores orange in mass, pale yellow by transmitted light, 8-11 x 3.5-4 microns, short-allantoid, finally 1-septate, conidia spherical or subspherical, up to 2.5 x 2.5 microns; basidia clavate becoming furcate, (Martin)
