Description:Fomes fraxinophilus (Peck) Sacc.
Cultural characters: (PI. III, Fig. 2; Pl. IV, Figs. 7 to 11).
Growth characters. Growth moderately rapid, plates covered in three to four weeks. Advancing zone even, hyaline, appressed in narrow zone. Mat white, downy near margin, becoming compact felty around inoculum (one week), forming a uniform pellicle like soft chamois, which peels from agar readily (two weeks), with areas of raised velvety overgrowth, frequently along radii, usually bearing well-organized, poroid, waxy, fruiting surfaces (three to four weeks). Reverse unchanged to "pinkish buff" (9.OYR7.3/4.5). Odor none. On gallic and tannic acid agars diffusion zones moderately strong, no growth on gallic acid agar, 2.0-3.5 cm diameter on tannic acid agar.
Hyphal characters. Advancing zone: hyphae nodose-septate, frequently branched, with numerous anastomoses, 1.5-4.5 µm diameter. Aerial mycelium: (a) hyphae as in advancing zone; (b) fiber hyphae with thick walls, lumina narrow or apparently lacking, frequently branched and closely interwoven, 2.0-3.0 µm diameter; (c) basidiospores (from spore deposit) hyaline, even, ovoid, frequently truncate, walls fairly thick and refractive, 6. 0-7 .5 x 4.5-6.0 µm. Submerged mycelium: (a) hyphae as in advancing zone; (b) chlamydospores few to numerous, terminal and intercalary, ovoid to elongate, fairly thin-walled, 9.0-18.0 x 6.0-9.0 À¬m; (c) crystals numerous, needlelike.
Type of rot: white mottled rot of broad-leaved trees, usually Fraxinus spp.
Descriptions of cultural characters: Baxter (8), Campbell (42), Davidson, Campbell, and Blaisdell (64).
Cultures of Fomes fraxinophilus are distinguished from other species having an identical key pattern by the texture of the mat, the raised pored fruiting surfaces, which are frequently radically elongated, and the characteristic truncate spores. Secondary spores such as were described by Campbell (42) were not observed in the isolates studied. A note on the differences between cultures of F. fraxinophilus and F. ellisianus is included under the latter species.
