Description: | Colony diameters on Czapek’s Agar 2.0-2.5 cm in 14 days at 25°C; conidial heads radiate to columnar, dark terre verte to dusky green (R., Plate, XXXIII); mycelium white to yellow; reverse uncolored, amber yellow to olive lake (R., Plate XVI); cleistothecia yellow. Colony diameters on Malt Extract Agar 1.8-2.2 cm in 14 days at 25°C; conidial heads radiate, dark grass green to ivy green (R., Plate XXXI); mycelium white to yellow; reverse colorless or dull wax yellow to dull primuline yellow; cleistothecia yellow. Colony diameters on Czapek’s Agar with 20% added sucrose 3.5-4.5 cm in 14 days at 25°C; conidial heads radiate to columnar, ivy green to dark grass green (R., Plate XXXI); myce-lium white to yellow; reverse uncolored, yellow to pale green brown; stipes 60-360 × 4.0-16.0 μm, smooth, colorless, or pale brown to middle brown; vesicles globose or subglobose to obovoid or pyriform, 6.8-32.5 μm in diameter. Aspergilla uniseriate, phialides covering 1/2 to 4/5 of the vesicle, 3.2-9.3 × 3.0-5.3 μm. Conidia globose or subglobose to ovoid, 3.3-6.4 × 3.0-5.2 μm, rough to irregularly roughened. Cleistothecia globose to subglobose, yellow 60.0-168.0 μm in diameter. Asci 8-spored, subglobose to globose, 8.7-12.7 × 8.0-10.3 μm. Ascospores lenticular 3.8-5.2 × 3.3-4.8 μm, longitudinal furrow with two irregular ridges, convex surfaces irregularly roughened. | |||
