Summary: Features include 1) resupinate growth on wood, 2) a mould-like adherent fruitbody colored dull grayish brown, the surface smooth, the margin farinaceous to pruinose, the subiculum thin and colored as the spore-bearing surface, 3) spores that are round or irregularly round, echinulate, and pale brown, 4) subicular hyphae that are noticeably thick-walled, with clamp connections, and often irregular with swollen and torose segments.
Tomentella kootenaiensis has been found in BC and AB (Ginns(5)).
Fruiting body: resupinate, up to 0.025cm thick, mucedinoid [mould-like], adherent, spore-bearing area continuous; dull grayish brown; smooth; sterile margin farinaceous [mealy] to pruinose; subiculum "thin and not easily discernible", colored as fertile area; annual, (Larsen)
Microscopic: SPORES 8-11 microns in diameter, round to less frequently irregularly round sometimes flattened adaxially, echinulate, pale brown; BASIDIA 4-spored, 40-60 x 6-7(8) microns, clavate, with clamp connection at base, sterigmata up to 6 microns long; SUBHYMENIAL HYPHAE 3-5 microns wide, pale yellow to colorless, with clamp connections; SUBICULAR HYPHAE 4-7 microns wide, noticeably thick-walled, with clamp connections, often irregular and then with swollen and torose segments up to 9 microns wide, pale yellowish brown, (Larsen)
