| Description： |
CYA, 25°C, 7 days: colony diameters 18-21 mm, center plane, subcenter, margin sulcate, floccose, margin entire, narrow; mycelium pale yellow to pastel yellow (3A3-4); conidiogenesis sparse; exudates and soluble pigment absent; reverse orange white to light orange (5A2-4). MEA, 25°C, 7 days: colony diameters 19-21 mm, center raised, floccose, margin narrow, entire; mycelium white, yellowish white or pale yellow (4A2-3); gymnothecia abundant, embedded in the mycelium; conidiogenesis moderate, pale green-green (29A3-4); exudate and soluble pigment absent; reverse pale orange to light orange (5A3-4). G25N, 25°C, 7 days: limited growth. CYA, 5°C, 7 days: no germination. CYA, 37°C, 7 days: no germination. Gymnothecia soft, abundant, confluent, globose to subglobose, embedded in the mycelium, maturing in 2 weeks, with peridium composed of loosely interwoven hyphae, 429-556 × 317-492 μm, pale yellow to pastel yellow (2A3-4); ascomata initials comsisting of irregular, contorted, swollen cells, which developing into ascogenous hyphae; asci borne in chains, globose, to ellipsoidal, 8.7-10.7 × 7.9-10.3 μm, greenish white to pale green (30A2-3); as-cospores ellipsoidal, spinulose to spinose, 3.6-4.3 × 2.2-2.5 μm, pale yellow. Conidiophores and conidia: conidiophores on MEA borne from aerial mycelium; stipes septate, 254-337 × 2.4-3.6 μm, smooth, thin-walled; penicilli mostly biverticillate, less often irregularly ferverticillate; metulae in verticils of 4-8, smooth, 7.9-17.5 × 2.4-3.2 μm; phi-alides in verticils of 4-8, acerose, smooth, 9.5-15.8 × 2.4-3.2 μm, collula long, gradually tapering; conidia subglobose, ellipsoidal to pyriform, 2.8-3.6 × 1.6-3.2 μm, smooth, thin walled, borne in short, irregular columns. | |||
