Summary:
Features include a perennial, cream to tan pore surface, a floccose to fimbriate cream margin, and microscopic characters including small allantoid spores and incrusted hyphae projecting from the dissepiment edges. The description is derived from Gilbertson(1).
Skeletocutis stellae has been found in BC, WA, OR, ID, AB, NF, ON, AZ, CA, CO, MT, WY, ME, NY, and Europe, (Gilbertson).
Cap:
growing flat on wood, firmly attached, up to 0.8cm thick; sterile margin often rather wide, cream-colored, floccose to fimbriate
Flesh:
subiculum up to 0.5cm thick, firm-fibrous; white, not zoned
Pores:
5-7 per mm, cream to tan, glancing [showing a change in appearance from dull to lustrous when the orientation to light is changed]; tube layer rigid, indistinctly layered, each layer up to 0.3cm thick
Microscopic:
spores 4.6-6 x 0.7-1 microns, allantoid, smooth, inamyloid, colorless; basidia 4-spored, 10-16 x 4-5 microns, clavate, with basal clamp; cystidia none, cystidioles inconspicuous, 12.5-18 x 3-4.5 microns wide, fusoid, with basal clamp, hyphal pegs present; hyphae dimitic, skeletal hyphae of subiculum 2-6 microns wide, colorless, thick-walled, nonseptate, rarely branched, generative hyphae of subiculum 2-4 microns wide, "thin-walled, nodose-septate, with occasional branching"; hyphae of trama similar, "projecting hyphae at dissepiment edges heavily incrusted"
