Summary:
Features include a flat or shelf-like fruitbody that is light brown, becoming grayish to blackish, fine pores that are pale brown, mild taste, growth on dead hardwood, and microscopic characters. In North America it is common in eastern hardwood forests and occasional in western areas, and it is rare in central and southern Europe, USSR, and the Himalayas, (Gilbertson).
Brunneoporus malicola has been collected twice from BC (Ginns). It has also been found in WA, AB, MB, ON, PQ, AZ, CT, IA, IL, IN, KY, LA, MD, MI, MN, MO, MS, MT, NC, NH, NJ, NY, OH, PA, SC, SD, TN, VT, WI, WV, WY, central and southern Europe, USSR, and the Himalayas, (Gilbertson).
Cap:
growing flat or bent back in upper part into caps that project up to 1.5cm from wood, tough to corky, hard when dry, separable; upper cap surface pale woody brown, becoming grayish to blackish when old, at first finely tomentose, soon agglutinated bald, sometimes more scrupose (rough from small projecting pointed hyphal bundles); margin round and distinct, (Gilbertson), growing flat on wood with pore surface exposed, forming patches several centimeters across and tightly attached, or bent outward to form shelf-like cap, 1-3cm along wood and projecting 0.5-1.5cm, with upper surface cream to light brown, "tuberculate, smooth to appressed fine-tomentose", cap margin obtuse, margin of flat pore surface "distinctly bounded to somewhat fringed; general consistency corky, soft, hard when dry", (Breitenbach)
Flesh:
0.1-0.2cm thick, pale woody brown, (Gilbertson)
Pores:
3-4 per mm. and round and regular on horizontal parts, commonly more irregular, angular to sinuous, 2-3 per mm, in parts also larger and semi-daedaleoid, up to 3-4 mm long and about 1mm wide, often with sinuous walls; pale cinnamon to woody brown; tube layer up to 0.5cm thick, colored as pore surface or paler, (Gilbertson), 1.5-2(3) per mm, angular to somewhat elongated, some toothed-slit; "whitish when young, then pale brown to sand-colored"; tube layer 0.3-0.8cm thick, (Breitenbach)
Microscopic:
spores 7-10 x 2.5-4 microns, cylindric and usually arcuate close to apiculus, inamyloid, colorless; basidia 25-40 x 7-10 microns, clavate, with basal clamp connection; cystidia none; hyphal system dimitic, generative hyphae 2-4 microns wide, with clamp connections, thin-walled to slightly thick-walled in the context, skeletal hyphae predominant, 2-5 microns wide, "semisolid to thick-walled, straight to sinuous, usually unbranched, occasionally more branched", "narrow binding hyphae rare, solid, much branched with short branches 2-3 microns wide, observed only in the context", (Gilbertson), spores 7-9.5 x 2.5-3.5 microns, cylindric-elliptic, smooth, inamyloid, colorless, (Breitenbach)
