Summary:
Features include flat growth on wood, pale brown-violet color, and microscopic characters including amyloid spores. The description is derived from Gilbertson(1). It is common in North America.
Anomoporia bombycina has been found in BC, WA, OR, ID, AB, ON, PQ, AK, AZ, CA, CO, MA, MI, MT, NH, NM, NY, UT, WV, and WY, and also in Europe, USSR, China, and Japan, (Gilbertson)
Cap:
up to 0.3cm thick, in small patches to widely spread out, flat on wood with pore surface exposed, soft when fresh, fragile when dry, easily separable, margin fimbriate (fringed) to cottony, rarely with some scattered rhizomorphs, subiculum soft and up to 0.1cm thick; margin white to pale violet-brown, subiculum white to pale brown
Pores:
2-4 per mm. at maturity, at first round, but soon angular and more irregular, thin-walled; cream to lavender; tubes layer to 0.2cm thick, colored as pore surface
Microscopic:
spores 5-7 x 3-5 microns, broadly elliptic, smooth, amyloid, colorless; basidia 4-spored, 12-18 x 5-7 microns, broadly clavate, with long sterigmata, with basal clamp connection; cystidia and other sterile hymenial elements absent; hyphal system "monomitic, generative hyphae with clamps, thin-walled, richly branched, hyaline but with a few scattered yellowish crystals, 2-6 microns wide, in the context mostly 4-6 microns wide"
