Species Information
Summary:
Features include flat growth on wood with the white pore surface exposed, soft cottony white flesh, small pores, and microscopic characters including lunate to allantoid spores. The description is derived from Gilbertson(1).
Microscopic:
spores 3.5-4.5 x 1-1.5 microns, lunate [crescent-shaped] to allantoid [curved sausage-shaped], smooth, inamyloid, colorless; basidia 8-12 x 3-5 microns, clavate, with basal clamp; cystidia none, but "scattered, non-projecting fusoid cystidioles variably present in the hymenium, 15-20 x 3-4 microns"; hyphal system dimitic: generative hyphae 2-4 microns wide, thin-walled, with clamp connections, skeletal hyphae 2-5 microns wide, thick-walled, unbranched and straight to sinuous, "in old specimens often with a light incrustation and resembling small cystidia, in some specimens all skeletal hyphae smooth"
Notes:
Sidera lenis has been found in BC, WA, OR, ID, AB, NF, AK, AZ, CA, CO, FL, GA, MA, MT, NC, NM, NY, PA, TN, TX, UT, WY, and circumglobally in the conifer zone [so presumably in Europe and Asia], (Gilbertson).
Habitat and Range
SIMILAR SPECIES
Antrodia xantha is more chalky and crumbly, normally more yellowish, and often cracked. The spores are different, and skeletal hyphae have a weak amyloid reaction. (Gilbertson). Skeletocutis species lack incrusted hyphal tips (Ginns(28) who says that S. lenis was included in Skeletocutis despite the lack of incrusted hyphal tips).Habitat
annual, most common on dead conifers but also recorded on hardwoods, causes a white rot
