Taste:
mild (Gilbertson)
Microscopic:
spores 5-9 x 3.5-4.5 microns, oval to broadly elliptic, smooth, inamyloid, colorless, spores often glued together; basidia 4-spored, 15-18 x 5-7 microns, clavate, simple-septate at base; cystidia of two types: 1) frequent to rare, not or barely projecting from hymenium, 17-30 x 3-6 microns, cylindric, capitately incrusted, simple-septate at base, 2) gloeocystidia often projecting beyond hymenium, 33-45 x 6-10 microns, cylindric to fusiform, "thin-walled, with refractive contents, arising in subhymenium"; hyphae monomitic, hyphae of subiculum 2-5 microns wide, colorless, simple-septate, thin-walled to very thick-walled, often incrusted, hyphae of trama similar, (Gilbertson), spores 5-8 x 3-5 microns, broadly elliptic, smooth, (Arora)

Habitat and Range
SIMILAR SPECIES
Oxyporus similis has smaller spores and smaller pores, and one type of cystidia, (Gilbertson). Oxyporus cuneatus is found almost entirely on Western Red-cedar and usually has a definite cap, (Gilbertson). Oxyporus latemarginatus has wider hyphae, lacks gloeocystidia, and grows only on hardwoods, (Gilbertson). Oxyporus populinus is perennial with a cap, and fruits on live hardwoods with fruitbodies on stem cankers, (Ginns(28)). See also SIMILAR section of Ceriporiopsis aneirina.Habitat
annual or sometimes perennial, on dead wood of hardwoods and conifers, causing a white rot, (Gilbertson), single or more often in rows or fused masses on rotting hardwood logs and branches, less commonly on conifers, producing a white rot, (Arora)
