Type: — CHINA. Hubei Province: Jingzhou City , N 30°21′27.37″, E 112°19′58.37″. Holotype GZUIFR-EB1303M was isolated from farmland soil by Y. R.Wang

Colonies on PDA attaining 25 mm in 14 days at 26 °C, white, fluffy, round, margin regular; reverse light yellow; hyphae hyaline, smooth, 1.6–4.3 µm; racquet hyphae present, 8.6–15 × 3.2–6.5 µm. Terminal and lateral conidia mostly on short protrusions or on side branches, mostly solitary or forming chains, single-celled, occasionally twocelled, smooth-walled, oblong-ovate to oblong-ellipsoidal, 4.3–16.2 × 3.2–8.6 µm (x̅ = 7.8 ± 1.1 × 5.6 ± 0.2, n = 50), sometimes clavate, 8.6–25.9 × 3.2–10.8 µm, with broad basal scars (0.8–5.4 µm). Intercalary conidia present, solitary, tubby to oblong-clavate, 4.3–32.4 × 2.2–7.6 µm (x̅ = 15.8 ± 1.1 × 4.8 ± 0.2, n = 50). Chlamydospores absent.
