Species Information
Summary:
Features include 1) brackets that are broadly attached along fallen coniferous logs, 2) a rather sharp margin, 3) an upper surface that is ochraceous to brown, with concentric grooved bands, 4) tough leathery brown flesh, and 5) yellowish brown pores that are angular to weakly elongated radially. Kout(3) synonymize this species with Gloeophyllum mexicanum (Mont.) Ryvarden 1982. The description is derived from Gilbertson(1) except where indicated.
Odor:
no scent of anise when fresh
Microscopic:
spores 8.5-11(12) x 3-4(4.5) microns, cylindric, smooth, inamyloid, colorless, thin-walled, often difficult to see in dried specimens; basidia 4-spored, 25-42 x 7-8 microns, with basal clamp; cystidia or cystidioles scattered, "tapered to rounded, up to 35 microns long, in a few cases elongated to an almost whiplike tip, then up to 55 microns long, 4-8 microns in diam, slightly thick-walled and light yellowish when viewed in KOH", in some cases difficult to distinguish from immature basidia; hyphal system trimitic: generative hyphae 2-4 microns wide, thin-walled to slightly thick-walled, "with distinct clamps, often with oildrops in the protoplasm", skeletal hyphae 3.5-5.5 microns wide, golden to light rusty brown, thick-walled to solid, binding hyphae 1.5-3 microns wide, light yellowish, solid, moderately branched, rather rare mainly in old parts of flesh

Gloeophyllum protractum has been found in BC, WA, OR, ID, AB, MB, NWT, NB, NF, NS, ON, AK, AZ, CA, CO, DE, FL, ME, MI, MN, MT, NH, NJ, NM, NY, PA, SD, TN, UT, VA, VT, WI, WV, and WY, and it is circumpolar "through USSR and into Europe where it is absent from the western part", (Gilbertson).

Habitat and Range
SIMILAR SPECIES
Gloeophyllum trabeum is generally smaller, has a softer and more bald upper surface, and normally has more gills in the spore-bearing surface, where the pore walls in general are thinner and the pores smaller (3-4 per mm), (Gilbertson). Gloeophyllum protractum is separated from Gloeophyllum odoratum by the former''s lack of anise odor, thinner fruitbodies, and normally smoother and more bald cap surface, (Gilbertson).Habitat
"annual (perennial?)", on coniferous wood especially Pinus (pine), mostly on decorticated wood in open habitats, rarely on hardwoods like Populus and Quercus (oak), causes a brown rot
