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).
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"
Notes: Skeletocutis stellae has been found in BC, WA, OR, ID, AB, NF, ON, AZ, CA, CO, MT, WY, ME, NY, and Europe, (Gilbertson).
