Species Information
Summary:
Features include a light reddish brown to blackish, rough and/or concentrically grooved, tough-fleshed fruitbody that is shelf-like, bracket-like, or growing flat on wood with the pore surface exposed, pores that are circular to angular or maze-like and yellowish brown to reddish brown, tough flesh that is yellowish brown to reddish brown, growth on conifers, and microscopic characters including setae in the hymenium. It is a major cause of timber loss.
Chemical Reactions:
cap tissue blackening in KOH (Arora), all parts black in 3% KOH (Miller)
Odor:

Microscopic:
spores 4.5-7 x 3.5-5 microns, oval, smooth, inamyloid, colorless or becoming slightly yellowish in older hymenia; basidia 4-spored, 12-14 x 5-6 microns, broadly clavate, simple-septate at base; setae abundant, 40-50 x 10-14 microns, subulate [awl-shaped] to ventricose, thick-walled; hyphae of context of two types: 1) 3.5-7.5 microns wide, brown in KOH, thick-walled or thin-walled, rarely branched, simple-septate, 2) 2-3 microns wide, colorless, thin-walled, rarely branched, simple-septate, (Gilbertson), "spores 4-6 x 3.5-5 microns, round or nearly round, smooth", (Arora)
