Description:Fomes scutellatus (Schw.) Cooke (Pl. IV & Pl. IX, 33-34) Key Pattern: 2 2 1 1 5 2 2 2 3 2 1
GROWTH CHARACTERS.-Growth slow, 1.5 cm in 1 week. Advancing zone hyaline, uneven, lobed, appressed. Mat white to `tawny' to `russet', at first cottony to cottony-woolly, floccose-cottony in some areas, which gradually changes subfelty to felty and floccose-felty. Floccose-woolly isolated areas are formed, colour of which changes from white to brown with age. Crustose areas are formed within two to three weeks. Reverse slight brownish after five weeks. Odour none.
Tests for extracellular oxidase positive; on gallic and tannic acid agars, diffusion zones weak and moderately strong respectively; growth nil on former, trace to 0.5 cm on latter, guaiacum reaction moderately strong.
HYPHAL CHARACTERS.- Advancing zone: hyphae hyaline, thin-walled, branched, nodose-septate, 1.5-3.8 µm diameter. Aerial mycelium: (a) hyphae as in advancing zone, hyaline to pale brown, slightly thick-walled; (b) fibre hyphae thick-walled, branched, aseptate, 2.0-3.2,u diameter; (c) pseudoparenchyma composed of closely packed, slightly thickwalled, irregular interlocking hyphae. Submerged mycelium: hyphae as in aerial mycelium.
