Summary:
Oxyporus similis forms whitish pore layer growing flat on hardwoods especially Populus, best differentiated from similar species by microscopic characters including heavily incrusted thick-walled cystidia. The description is derived from Gilbertson(1).
Microscopic:
spores 4-5 x 2.5-3 microns, elliptic to oval, smooth, inamyloid, colorless; basidia 4-spored, 12-17 x 3-5 microns, clavate, simple-septate at base; cystidia abundant, 25-55 x 7-8 microns, clavate, heavily incrusted over apical part, wall thickened toward apex, simple-septate at base; hyphae monomitic, hyphae of subiculum 2-4 microns thick, thin-walled to thick-walled, simple-septate, with occasional branching
Notes:
Oxyporus similis has been found in BC, WA, OR, ID, MB, AZ, CA, CO, and MT, (Gilbertson).
Habitat and Range
SIMILAR SPECIES
Oxyporus corticola has larger pores, larger spores, and two types of cystidia, (Gilbertson). Oxyporus cuneatus grows almost entirely on Western Red-cedar and usually has a definite cap, (Gilbertson). O. cuneatus grows on conifers, has pores 3-4 per mm, and has thin-walled cystidia and gloeocystidia, (Ginns). Oxyporus latemarginatus has larger pores and spores, (Gilbertson). Oxyporus populinus also grows on hardwoods but fruitbodies have a cap.Habitat
annual, growing on dead hardwoods, rarely on conifers, most common on Populus, and particularly common on Populus trichocarpa (Black Cottonwood) in northern Idaho and Montana; associated with white rot of hardwoods and conifers
