Species Information

Summary:
{See also Dacrymyces Table.} Dacrymyces chrysospermus is characterized by large, typically bright orange fruiting bodies that dry orange red to orange brown, distinctly 7-septate spores, and lack of clamp connections (McNabb). It is a common fungus in the Pacific Northwest. Advice about edibility differs: not edible (Phillips), edible, but should be boiled or steamed not sauteed, (Lincoff).
Microscopic:
spores 16.5-23(26.5) x 5-7.5 microns, curved-cylindric, "relatively thin-walled with slightly thickened and distinct septa, tinted, apiculate", becoming 7-septate by maturity, germination by colorless oval conidia or by germ tubes; probasidia 50-83 x 4-6.5 microns, cylindric-subclavate, with basal septa, becoming bifurcate; hymenium consisting of basidia and occasionally simple cylindric dikaryophyses; internal hyphae "thin-walled, smooth or roughened, septate, clamp connections absent", hairs on stem and base of cap simple, cylindric or subclavate, externally roughened, thick-walled, (McNabb), spores 17-25 x 6-8 microns, cylindric, curved, finally 7-septate, deep orange in mass, yellow by transmitted light, conidia 2 x 1.5 microns, ovoid or somewhat elliptic; "internal hyphae smooth or rarely somewhat roughened, with occasional or frequent clamp-connections, these apparently lacking in some collections", (Martin), spores 17-25 x 6-8 microns, cylindric to sausage-shaped, smooth, becoming 8-10-celled, spore deposit yellowish, (Phillips), bearing a varying number of clavate, cortical hairs with thick gelatinous walls on stem and rooting base, (Kennedy)
Notes:
It is found in BC, WA, OR, ID, AB, NB, NF, NS, ON, PQ, YT, AL, AZ, CA, CT, IN, LA, MA, MI, MN, NH, NM, NY, PA, SC, VT, and WI, (Ginns), temperate North America and eastern Asia, (Martin), Finland, Germany, Japan, Christmas Island, Lord Howe Island, Mauritius, Socotra, South Africa, and Tibet in China, (McNabb), Belorussia, Estonia, and Russia, (Raitviir), United, Kingdom, and reported from Czechoslovakia, Estonia, Italy, Norway, Poland, Russia, Sweden, Switzerland, and New Caledonia, (Reid).

Habitat and Range

SIMILAR SPECIES
Tremella mesenterica lacks white basal attachment and grows on deciduous wood, besides being different microscopically, (Lincoff). Dacrymyces stillatus is smaller, simpler in form, and different microscopically. Dacrymyces chrysocomus is smaller, yellow, and cushion-shaped to cup-shaped. Dacrymyces capitatus is smaller, yellow, usually grows on hardwoods, and differs microscopically.
Habitat
saprophytic on stumps; logs, brush; stub; causes a uniform brown rot or a brown pocket rot, (Ginns), conifer and hardwood, (McNabb)
