Summary:
Skeletocutis odora is characterized by a strong garlic-like odor when fresh, and microscopically by allantoid spores and few skeletal hyphae. Polyporus odorus Peck is a synonym but not Polyporus odorus Sommerf.: Fr. The description is derived from Gilbertson(1). It is apparently rare in eastern North America but common in the southwest, especially on Ponderosa pine, (Gilbertson).

Odor:
garlic-like when fresh

Microscopic:
spores 4.5-6 x 1-1.5 microns, allantoid, inamyloid, colorless; basidia 12-16 x 4-5 microns, clavate, with basal clamp connection; cystidia none, but "fusoid non-projecting cystidioles may occur scattered among the basidia, but often difficult to observe in old hymenia, 10-12 microns long"; hyphal system dimitic, generative hyphae 2-4.5 microns wide, with clamp connections, thin-walled, skeletal hyphae rather few, 2.5-4 microns wide, thick-walled to semisolid, straight and unbranched

Notes:
Skeletocutis odora has been found in BC, (Ginns(27)). It has also been found in OR, NB, AK, AZ, NM, NY, TX, and PA, (Gilbertson). Note that some records could represent the more recently described Skeletocutis subodora.
