Summary: Features include flat loosely attached growth on wood, a yellow pore surface, a margin with yellow rhizomorphs, amyloid spores, and other microscopic characters. This species is very rare (Gilbertson). The description is derived from Gilbertson(1) except where noted.
Microscopic: spores 3-5 x 2.5-3.5 microns, elliptic to nearly round, smooth, amyloid, colorless, thin-walled; basidia 4-spored, 17-22 x 5.5-7 microns, clavate, with basal clamp connection; cystidia and other sterile hymenial elements absent; hyphal system monomitic, generative hyphae with clamp connections, in the subiculum and margin 2.5-5 microns wide, smooth to finely encrusted, thin to slightly thick-walled, sparingly branched, in trama and subhymenium 2-4 microns wide, thin-walled, smooth
Notes: Anomoloma albolutescens has been found in BC, WA, OR, ID, also AB, AK, CO, IN, MI, NC, NY, TN, and VT, (Gilbertson)
Habitat and Range
SIMILAR SPECIES
Anomoloma myceliosum is separated mainly by its white pore surface and rhizomorphs (Gilbertson). Anomoporia bombycina is common: it has a pore surface that is yellowish tan to lavender, rhizomorphs are usually absent, and spores are larger, (Gilbertson).
Habitat
annual; on coniferous wood, causing a brown rot, more rarely on hardwood such as maple or birch, (Gilbertson(1)), causes a white rot: contrary to previous reports, does not cause a brown rot (Ginns)
