Summary: {See also Dacrymyces Table.} Dacrymyces minutus is characterized by small fruiting bodies, thick-walled cortical hairs, and 3-septate spores (McNabb 1973). The fruiting bodies are shallowly cushion-shaped to cup-shaped, gregarious, and dull orange to bright orange-yellow when fresh.
Microscopic: spores 13-18(19.5) x 4.5-6(7) microns, curved-cylindric, tinted, thin-walled with thin septa, apiculate, becoming 3-septate at maturity, germination by colorless conidia or by germ tubes; probasidia 30-58 x 4.5-6 microns, cylindric to cylindric-subclavate, with basal clamp connections, becoming bifurcate; hymenium "confined to surface of disc or interior of cup, composed of basidia and occasionally simple, cylindrical dikaryophyses"; cortex "covered with thick-walled, simple or branched, clamped hairs, terminal cells varying in shape from narrowly clavate to broadly obovate, smooth, to 50 x 11 microns"; internal hyphae "thin-walled, roughened, clamp connections present", (McNabb)
Notes: It is been found in BC, WA, NC, and SC, (Ginns).
