Description : PHELLINUS EVERHARTII (Ell. et Gall.) Ames, Ann. Myc. 11:246. 1913. Mucronoporus everhartii Ell. et Gall., Jour. Myc. 5:141. 1889. Fomes everhartii (Ell. et Gall.) von Schrenk et Spaulding, U.S. Dept. Agr. Pl. Ind. Bul. 149:48. 1909.

Basidiocarps sessile, ungulate, up to 6 × 13 × 8 cm; upper surface yellowish brown to blackish, sometimes very finely tomentose, becoming glabrous and incrusted with age, usually sulcate, rimose; margin concolorous, rounded; pore surface glancing with a golden luster, dark yellowish- to reddish brown (Ochraceous-Tawny, Buckthorn Brown or Cinnamon Brown), the pores circular to angular, 5-6 per mm, with thick, entire dissepiments; context reddish brown, woody, faintly zonate, up to 5 cm thick; tube layers concolorous with the context, rather distinctly stratified, each layer up to 6 mm thick; context with masses of hard granular tissue that appear under 30X lens as dark, solid or resinous areas in a matrix of paler brown interwoven mycelium; hyphae of dark masses agglutinated and hard to separate, tissue breaking out in small chunks.
Contextual hyphae mostly brown in KOH solution, thin- to thick-walled, with rare branching, simple-septate, 3-6.5 µm in diam, some hyphae hyaline, thin-walled, simple-septate, 2.5-4 µm in diam; tramal hyphae similar.
Setae frequent to abundant, subulate to ventricose, thick-walled, 16-36 × 5-9 µm.

Basidia ovoid to broadly ellipsoid or subglobose, 4-sterigmate, 8-12 × 5.5-7 µm, simple-septate at the base.
Basidiospores ovoid to subglobose, dark reddish brown, smooth, negative in Melzer’s reagent, 4-5 × 3-4 µm.

Type of rot – White rot of heartwood of living oaks.

Cultural characteristics – See Campbell (1938), Davidson et al. (1942), and Nobles (1948, 1958, 1965).
Substrata – Quercus arizonica, Q. emoryi, Q. gambelii, Q. garryana. Distribution – AZ, CA, ID, MT, MEXICO, NM, and OR.
Voucher specimens – RLG 7014 (ARIZ).

Remarks – Fomes everhartii is a common species in the oak forests of the southwestern U.S., but is rarely found elsewhere in the West. The dark reddish brown spores, the thin-walled septate hyphae, and thick ungulate fruiting bodies are characteristic features. It is similar to P. weirianus but has smaller setae. Furthermore, P. weirianus is restricted to walnut.
