Description: | CYA, 25°C, 7 days: colony diameters 28-29 mm, center somewhat raised, sulcate, dense, velutinous, occasionally floccose, margin entire, narrow; mycelium white; conidiogenesis abundant, dark green (26F4-6, 27F4-6); exudate and soluble pigment absent; reverse greyish brown, brown (6E3-5) or greyish brown to yellowish brown (5E3-5). MEA, 25°C, 7 days: colony diameters 35-38 mm, plane, low, velutinous, margin entire, ef-fuse, somewhat narrow; mycelium white; conidiogenesis abundant, dark green (26F4-6); exudate and soluble pigment absent; reverse olive (3D3-5). G25N, 25°C, 7 days: colony diameters 5-9 mm, wrinkled, velutinous, margin entire wide; mycelium yellowish grey to greyish yellow (3C2-3) or dull yellow (3B2-3); conidiogenesis sparse; exudate and soluble pigment absent; reverse greyish yellow (4C4-5). CYA, 5°C, 7 days: germination with restricted growth. CYA, 37°C, 7 days: no germination. Conidiophores and conidia: conidiophores on MEA borne from superficial mycelium; stipes septate, 19-250 × 1.6-3.2 μm, finely roughened to roughened, thin-walled; penicilli mostly biverticillate, often monoverticillate; metulae in verticils of 2-3, roughened, 10.3-29.4 × 1.6-3.2 μm; phialides ampulliform, in verticils of 5-10, smooth to finely roughened, 6.3-9.5 × 2.4-3.6 μm, mostly short, sometimes collula up to 1.6 μm in length; conidia subspheroidal, less often ellipsoidal, 2.4-3.6 μm, finely roughened, thin walled, borne in loose, disordered, entangled chains. | |||
