Species Information
Summary:
Features include 1) resupinate growth on dead conifer wood, 2) fruitbodies that are membranous to waxy, tightly attached, and cream buff, with the margin abrupt or thinning out, 3) spores that are large, broadly cylindric, smooth, inamyloid, and colorless, 4) cystidia that are large, clavate, encrusted, and thick-walled in their lower part, and 5) a monomitic hyphal system, the hyphae with clamp connections.
Microscopic:
SPORES 8-12 x 4.5-6 microns, broadly cylindric, smooth, inamyloid, colorless, acyanophilic, thin-walled; BASIDIA 4-spored, 40-80 x 6.5-8 microns, clavate, thin-walled, with basal clamp connection, sterigmata up to 8 microns long; CYSTIDIA "numerous, arising from various depths in subhymenium", 100-280 x 8-16 microns, projecting to 80 microns, clavate, "thin-walled at first, later thick-walled at base then gradually thinning toward apex, with basal clamp", entirely or partially covered with a thin layer of colorless, resinous or crystalline material; HYPHAE monomitic, SUBHYMENIAL HYPHAE 4-6 microns wide, "arranged vertically, dense and compact", "thin-walled, nodose septate", SUBICULAR HYPHAE 4-6 microns wide, thin-walled to moderately thick-walled, "nodose septate, frequently branched", (Nakasone), |SPORES 7-9 x 4.5-5.5 microns, broadly elliptic, "flattened and appearing straight on one side with lateral apiculus", smooth, inamyloid, thin-walled; BASIDIA 4-spored, 30-40 x 6.5-7.5 microns, clavate, sterigmata subulate, slightly arcuate; CYSTIDIA numerous, arising in subhymenium and extruded 3/4 of length, 70-150 x 7.5-12 microns, clavate, apex obtuse, walls thin in upper part but irregularly thickened in lower part, encrusted in upper part with resinous material; SUBICULUM "with a basal layer of interwoven, in part horizontal, hyphae, 3.5-4.5 microns broad with thickened walls, upper layer of more or less erect hyphae with thin walls, all with clamps, a considerable amount of resinous material present", (Jackson), |SPORES 7-9 x 4.5-5.5 microns, broadly elliptic, inamyloid, colorless; CYSTIDIA abundant, clavate, with walls strongly thickened at base, encrusted apically with resinous material; hyphae with clamp connections, (Gilbertson)
Notes:
Crustoderma resinosum has been found in BC, WA, OR, AB, and MT, (Ginns).
Habitat and Range
SIMILAR SPECIES
Crustoderma dryinum has cylindric to cylindric elliptic spores measuring 8-12 x 3-4 microns, and cystidia with their walls moderately thickened (as opposed to strongly thickened) at the base, (Gilbertson). Crustoderma testatum has dendrohyphidia and two types of cystidia. Crustoderma longicystidiatum is very rare and among other differences is not corneous when dried.Habitat
on dead conifers; associated with a brown rot, (Nakasone), on barkless wood, (Jackson), on dead wood; Picea glauca (White Spruce), P. sitchensis (Sitka Spruce), Pinus contorta (Lodgepole Pine), Pseudotsuga menziesii (Douglas-fir), (Ginns)
