Species Information

Summary:
When typically developed this is an easy species to recognize because of its quite thick basidiocarps with a hispid to villose, often grayish pileus, large pores, and a brown pore-surface and context; found in BC, WA, OR, ID, also AB, MB, NS, SK, AR, AZ, CA, CO, IA, IL, IN, KS, LA, MI, MN, MO, MT, ND, NE, NH, NM, NY, OH, OK, TX, UT, WI, WY, (Gilbertson), also Europe, Asia, Africa, (Breitenbach)
Cap:
with cap and no stem, cap "up to 10cm wide, 7cm broad, and 1cm thick, semicircular or elongated", often several imbricate [shingled] caps bent back from a common part flat on the wood (with pore surface exposed), corky to tough; at first brownish, soon dirty gray; zoned or not zoned, densely hirsute (with coarse elongated hairs) to hispid (with stiff erect hairs), more hispid at base than at margin, "the hirsute tomentum is clearly differentiated towards the brown context", (Gilbertson), bracket-like, shelf-like or entirely flat on wood, semicircular to linear, individual caps 10-15cm along wood, projecting 2-6(10)cm, 1-3cm thick, dark brown, rust-brown to gray-ocher-brown; "coarsely hispid-tomentose, +/- zoned, sometimes rather radially furrowed, hairs stiff and some agglutinated into tufts", cap margin sharp, somewhat lighter in color than cap surface when young, appressed-tomentose and slightly undulating, (Breitenbach)
Flesh:
mostly thin, more rarely up to 1cm thick; rusty to umber brown, (Gilbertson), 0.5-1cm thick, corky, tough; brown, (Breitenbach)
Pores:
1-3mm in diameter, angular, thin-walled, "in larger and older specimens often radially elongated and deeply split"; brown to gray; tube layer up to 1.5cm thick, whitish to gray on inner walls, trama between tube walls brown, (Gilbertson), 1-2(3) per mm, rounded angular, sometimes also oblong; ocher-brown when young, later gray brown to dark brown; tube layer up to 1cm thick, (Breitenbach)
Chemical Reactions:
flesh at first black in KOH, then fading back to almost the original color
Microscopic:
spores 10-16 x 3-5 microns, cylindric, smooth, inamyloid, colorless, thin-walled, spores sometimes varying considerably even in the same fruitbody; basidia 20-40 x 5.5-8 microns, clavate; cystidia absent; hyphal system trimitic: generative hyphae 2-4.5 microns wide, thin-walled, colorless and clamped, binding hyphae 2.5-4.5 microns wide, "tortuous, thick-walled to almost solid, light golden brown", skeletal hyphae 2.5-6 microns wide, "thick-walled to solid, golden brown in trama and context, hyaline in the tomentum", (Gilbertson), spores 10-15 x 4.5-5.5 microns, elliptic-cylindric, smooth, inamyloid, colorless, (Breitenbach)
Spore Deposit:
white, (Buczacki)

Habitat / Range

annual, on dead hardwood, most common on Salix (willow) and Populus spp., very rarely on conifers, (Gilbertson), single or in groups or rows on dead or living wood of hardwoods, (Breitenbach), fall (Buczacki)
