Notes on Taxonomy: [Edit] Brief Description:

Literature :
Gilbertson, R.L.; Ryvarden, L. 1986. North American Polypores. 1:1-443

Page number : 263
Remarks (public) : Fomes fasciatus and F. fomentarius have ranges that overlap slightly in Tennessee and North Carolina. Fomes fasciatus, however, is essentially a southern and subtropical species and F. fomentarius is a boreal species. F. fomentarius basidiocarps tend to be more consistently ungulate and typically have a concave pore surface. Basidiocarps of F. fasciatus vary greatly from applanate to ungulate and generally have a convex pore surface. Microscopically, they differ in the larger spores of F. fomentarius.

Basidiocarps perennial, sessile, ungulate to applanate, up to 10 × 18 × 10 cm, upper surface at first light brown, minutely tomentose, faintly zonate, soon becoming hard and crustose, glabrous, gray to dark brown or black, concentrically sulcate, zonate to completely black and azonate, pore surface light brown, darkening with age, the pores circular, 4-5 per mm, with thick, entire dissepiments, context lustrous golden brown on cut surfaces, distinctly to faintly zonate, fibrous, with a dark, hard, crustose upper layer up to 1 mm thick, sharply differentiated from fibrous context, a central core of granular, mottled tissue developing near substrate, tube layers indistinctly stratified, sometimes separated by a thin layer of context, tubes paler within.
Hyphal system trimitic, contextual generative hyphae with clamps, thin-walled, 2.5-4 µm in diam, difficult to find in mature specimens, contextual skeletal hyphae thick-walled, nonseptate, pale yellowish brown in KOH, with rare branching, 3-8 µm in diam, binding hyphae thick-walled, much branched, hyaline to pale yellowish brown in KOH, 1.5-4 µm in diam, irregularly shaped sclerids abundant in core tissue, thick-walled, golden to reddish brown in KOH, tramal hyphae similar except for sclerids.
Cystidioles fusoid, thin-walled, 20-25 × 6.5-8 µm, with a basal clamp. Basidia broadly clavate, 4-sterigmate, 19-22 × 8-10 µm, with a basal clamp. Basidiospores cylindric, hyaline, smooth, negative in Melzer’s reagent, 12-14 × 4-4.5 µm.
Type of rot. – White rot of heartwood of living hardwoods, also dead hardwoods.
Cultural characteristics. – See Campbell 1938 (as Fomes marmoratus ), Stalpers 1978 (as Fomes sclerodermeus).
Sexuality. – Unknown.
Substrata. – On living and dead hardwoods in numerous genera, also Nothofagus. Distribution.Southeastern U.S. and Arizona.
