Summary:
Features include an annual cream to pinkish pore surface, a floccose to fimbriate white margin, and microscopic characters including small allantoid spores and incrusted hyphae projecting from the dissepiment edges. The description is derived from Gilbertson(1).
Skeletocutis subincarnata is widespread in the southern part of BC (Ginns(28)). It has been found in ID, AB, NF, AK, AZ, CA, ME, MN, MT, NY, and TX, (Gilbertson).
Cap:
growing flat on wood with pore surface exposed, (or rarely slightly bent outward to form shelf-like cap), separable or somewhat firmly attached, often cracking on drying; margin "narrow, white, tomentose to fimbriate or rarely with white rhizomorphs"
Flesh:
subiculum thin, soft, fibrous; whitish
Pores:
5-7 per mm, "creamy-white or with a pinkish cast when fresh, drying cream to buff"; tube layer up to 0.4cm thick, soft-waxy to coriaceous [leathery]
Microscopic:
spores 4-6.5 x 1-1.5 microns, allantoid [curved sausage-shaped], smooth, inamyloid, colorless; basidia 4-spored, 12-15 x 4-5.5 microns, clavate, with basal clamp; cystidia none, cystidioles 9.5-16 x 3-5.5 microns, fusoid, with basal clamp, hyphal pegs conspicuous; hyphae dimitic, skeletal hyphae of subiculum 2-4 microns wide, colorless, thick-walled, nonseptate, rarely branched, generative hyphae of subiculum 2-3 microns wide, "thin-walled, nodose-septate, with occasional branching"; hyphae of trama "similar, heavily incrusted at the dissepiment edges"
