GenBank: KT948765 MycoBank: MB 814991

Type: — CHINA. Guizhou Province: Kaiyang County, N 27°19′51.07″, E107°09′59.78″. Holotype EM14.2002 was isolated from the soil under the dried snakeskin collected in Guizhou Province by Y. R. Wang.

Colonies on Czapek agar, attaining 18–20 mm in 14 d at 25 °C, white, fluffy, round. Colonies on PDA attaining 44–54 mm, white, fluffy, dense in the middle, sparse near the margin. Reverse yellowish. Hyphae hyaline to subhyaline, septate, smooth, 1.2–4.3 μm wide. Racquet hyphae present, 6.5–19.4 × 4.3–7.6 µm. Terminal and lateral conidia on short protrusions or side branches, solitary, hyaline, smooth, mostly single–celled, occasionally double–celled, subglobose, 2.2–4.3 µm; obovate to ellipsoidal, 5.4–6.5 × 3.2–4.3 µm (x = 5.5 × 3.8, n= 60). Intercalary conidia abundant, appearing on the long lateral branches, barrel-shaped, irregularly cylindrical or ellipsoidal, 2.2–24.9 × 1.3– 4.3 µm; basal scars 0.8–2.5 µm.

Etymology: —Refers to the region from which the fungus was isolated.
