Aspergillus terreus Thom, Apud Thom & Church, Am. J. Bot. 5: 85. 1918.

 Description: Colony diameters on Czapek’s Agar 3.0-3.5 cm in 10 days at 25°C, floccose, radially furrowed, margin irregular; mycelium white; conidial heads yellowish white to vi-naceous-buff (R., Plate XL); mycelium white; soluble pigment pale cream-buff (R., Plate XXX); reverse light brown to dark brown; vesicles 8.0-20.0 μm in diameter, pyriform or hemispherical (dome-like); stipes 48-220 × 4.0-8.6 μm, smooth, uncolored, mostly flexuous. Aspergilla biseriate, metulae crowded, covering upper 1/2 to 2/3 of the vesicle, 4.8-7.2 × 2.0-3.6 μm; phialides 5.6-8.0 × 1.6-2.8 μm. Conidia globose to subglobose, 1.5-3.4 μm in diameter, smooth. Colony diameters on Malt Extract Agar 6.5-7.0 cm in 10 days at 25°C, conidial heads columnar, avellaneous to wood brown (R., Plate XL); reverse greyish yellow; soluble pigment light yellow. Globose to ovoid hyaline cells often produced from the side of submerged hyphae, 3.6-6.4 μm in diameter.
