Species Information
Summary:
Features include 1) a very thin fruitbody growing flat on conifer wood with pores facing outward, 2) small, angular pores in a surface that is white becoming cream or pale brown, 3) a narrow margin that is cottony or membranous, and 4) microscopic characters. It is rare in the Pacific Northwest.
Microscopic:
spores 4.0-5.5 x 1.3-1.8 microns, allantoid; cystidioles common, (5.5)9.0-12.0 x 3.8-5.5 microns, fusoid, apices conic; generative hyphae "predominate in context and trama", 2-4 microns wide, with clamp connections, walls thin and colorless, "those at pore mouths sparsely crystalline-encrusted and not inflated", skeletal hyphae few, 2.8-3.6 microns wide, wavy, "walls thick, becoming gelatinized and dissolving in KOH"
Notes:
In North America, Skeletocutis albocremea is only known from three BC collections (Ginns(28)).
Habitat and Range
SIMILAR SPECIES
Skeletocutis subincarnata "is similar in some respects" but differs in having 1) thicker fruitbodies that are relatively loosely attached to the wood, 2) sometimes a pink tint, 3) "slightly longer, slightly narrower spores", and 4) "relatively less incrustation of the hyphae in the context and trama", (Ginns(28)).Habitat
on Picea engelmannii (Engelmann Spruce) and Pseudotsuga menziesii (Douglas-fir), "causing a white rot"
