white loose-cottony zones alternating with subhyaline short cottony zones, cottony over the inoculum. Reverse unchanged. Odour none.

HYPHAL CHARACTERS.-Advancing zone: hyphae hyaline, thin-walled, branched, with frequent clamp connections, 1.5--4.0 µm diameter. Aerial mycelium: (a) as in advancing zone thin to slightly thick-walled, (b) fibre hyphae thick-walled, with narrow lumen, unbranched, aseptate, 2.5-5.0 µm diameter. Submerged mycelium: hyphae as in aerial mycelium.
