Summary:
Features include 1) caps growing on spruce, often in shingled fashion, the cap surface white then more sordid brown to grayish, and tomentose to velvety becoming more coarsely hairy with radial lines, 2) a pore surface that is shiny and white becoming browner, 3) soft but tough texture, the flesh developing dark lines, 4) sweet taste, 5) an associated stringy white rot, and 6) microscopic characters including small elliptic spores. The description is derived from Gilbertson(1).
Taste:
sweet
Microscopic:
spores 2.5-3 x 2-2.5 microns, elliptic, ovoid or nearly round to almost pear-shaped, inamyloid, colorless; basidia 12-16 x 4-6 microns, clavate, with basal clamp; cystidia none but "conical, non-projecting cystidioles scattered among the basidia, 12-15 x 5-6 microns"; hyphal system dimitic, generative hyphae 3-5 microns wide, predominant in context, thin to thick-walled, with clamp connections, the same type present in trama but here mixed with agglutinated skeletal hyphae, 2-5 microns wide, thick-walled to solid
