Species Information
Summary:
Features include 1) a purplish brown pore surface growing flat and tightly attached on conifer wood, 2) soft to tough, yellowish brown flesh that splits easily, and 3) microscopic characters including setae that present as ends of setal hyphae, bending abruptly and projection into the tubes.
Microscopic:
spores 4-5.5 x 1-1.5 microns, cylindric, curved, smooth, inamyloid, colorless; basidia 4-spored, 12-14 x 3.5-4 microns, narrowly clavate, simple-septate at base; setae "present as ends of setal hyphae, bent abruptly and projecting into the tubes"; hyphae of context of 2 types 1) 2.5-5 microns, brownish to colorless, thin-walled to thick-walled, simple-septate, with occasional branching, 2) 3.5-5 microns, dark brown, thick-walled, rarely branched, rarely septate; hyphae of trama similar, (Gilbertson), spores 4-5 x 1.5-1.8 microns, cylindric, allantoid, smooth, inamyloid, colorless; setae very numerous, 5-8 microns wide, acuminate, some curved, dark-brown, thick-walled to solid, (Breitenbach)
Notes:
Phellinidium ferrugineofuscum has been found in BC, WA, OR, ID, AB, ON, SK, AK, AZ, CA, CO, IN, MI, MN, MT, NC, NY, OH, UT, WI, and WY, (Gilbertson). It also occurs in Europe and Asia, (Breitenbach).
Habitat and Range
SIMILAR SPECIES
Phellinidium weirii and Fuscoporia ferruginosa also have setal hyphae and colorless spores, but differ in consistency and color of fruitbody and spore shape, (Gilbertson). P. weirii, F. ferruginosa, and Phellinidium sulphurascens "also occur on conifers and have setal hyphae" and colorless spores, but the spores of those three species are wider and their fruitbodies are differently colored, (Ginns(28)). Inonotus glomeratus also has setal hyphae and frequently grows flat on wood but occurs on hardwoods and has yellowish oval spores, (Gilbertson).Habitat
annual or with 2 layers of tubes, on dead wood of conifers, especially common in spruce-fir zone, associated with white laminated rot of dead wood of conifers, the wood "often has small longitudinal pits similar to those seen in wood decayed by P. weirii. The wood is also frequently mottled with transversely oriented white streaks and may have flecks scattered through it.", (Gilbertson), perennial (Breitenbach)
