Summary: Features include flat growth on wood, a white pore surface, a wide white fringed margin with white rhizomorphs, and microscopic characters including amyloid spores. The description is derived from Gilbertson(1).
Microscopic: spores 3.5-4.5 x 2.5-3 microns, cylindric-elliptic, smooth, amyloid, colorless; basidia 4-spored, 12-20 x 4-5 microns, clavate, with basal clamp connection; cystidia and other sterile hymenial elements absent; hyphal system "monomitic, generative hyphae with clamps, thin-walled, with frequent branching", 2.5-4 microns wide

Habitat and Range
SIMILAR SPECIES
Anomoloma albolutescens has a yellow pore surface and yellow rhizomorphs (Gilbertson). Anomoporia bombycina has a yellowish tan to lavender pore surface, usually absent rhizomorphs, and larger spores, (Gilbertson). Ceriporiopsis mucida is morphologically similar but has spores with inamyloid walls (Ginns). See also SIMILAR section of Anomoloma albolutescens.
Habitat
annual; on fairly rotten conifer wood, causing a white rot, rarely on hardwood such as Betula (birch)
