Summary: Features include bracket-like yellowish brown fruitbodies on living and dead hardwoods, small dark purplish red-brown pores, and microscopic characters including setae. Wagner(1) transferred this species to Fuscoporia gilva (Schw.: Fr.) T. Wagner & M. Fischer on the basis of molecular and other work.
Chemical Reactions: cap tissue blackening in KOH (Arora)
Microscopic: spores 4-5 x 3-3.5 microns, elliptic to oval, smooth, inamyloid, colorless; basidia 4-spored, 5-11 x 5-7 microns, broadly clavate, simple-septate at base; setae abundant, 20-30 x 5-6 microns, subulate [awl-shaped], sharp, dark brown in KOH, thick-walled; hyphae of context of 2 types: 1) 3-7 microns wide, "dark reddish brown in KOH, thick-walled, rarely branched, simple-septate", 2) 3-5 microns wide, "pale yellowish brown, thin-walled, with occasional branching, simple-septate"; hyphae of trama similar, (Gilbertson), spores 4-5 x 2.5-3.5 microns, oblong-elliptic, smooth, rarely found, (Arora)
Spore Deposit: whitish (Arora)

Habitat and Range
Habitat
often perennial, single or more often in groups on dead or occasionally living hardwoods, producing a general delignifying decay of sapwood, making it whitish and brittle; rarely on conifers, (Arora), perennial or annual, on living and dead hardwoods, especially oak, rarely on conifers, associated with a uniform white rot of dead wood of hardwoods and a heart rot of living trees, (Gilbertson)
