Summary:
Oxyporus latemarginatus forms a whitish pore layer growing flat on hardwoods, and is best differentiated from similar species by microscopic characters including spores measuring 5.5-7.0 x 3-4 microns, and thin-walled apically incrusted cystidia (which may be rare). The description is derived from Gilbertson(1) except where noted.
Microscopic:
spores 5.5-7 x 3-4 microns, narrowly elliptic, smooth, inamyloid, colorless; basidia 4-spored, 16-20 x 5-7 microns, clavate, simple-septate at base; cystidia rare to frequent or in some specimens apparently absent, 20-28 x 4.5-6 microns, narrowly clavate to cylindric, apically incrusted, simple-septate at base; hyphae monomitic, hyphae of subiculum 3-8 microns wide, colorless in KOH, thin-walled, often branched, simple-septate, hyphae of trama similar
Spore Deposit:
white (Buczacki)
