Description

Colonies white, cottony, slow-growing on PDA medium, reaching 50 mm diameter after 18 days at 26°C. Mycelium hyaline, septate, branched, smooth. Conidiophores 125–335 µm (x̅ = 216.5 µm, n = 50) long, 3–6.5 µm (x̅ = 4.5 µm, n = 50) wide at the base, 2–3.5 µm (x̅ = 3 µm, n = 50) wide at the apex, hyaline, erect, septate, unbranched, bearing a single conidium at the apex. Conidia two types: Macroconidia 20–49.5 × 8.5–15 µm (x̅ = 38.5–12 µm, n = 50), hyaline, smooth, ellipsoid, broadly rounded at the apex, truncate at the base, 1–2-septate, mostly 2-septate. Microconidia 6.5–22 × 3.5–7 µm (x̅ = 15.5–5 µm, n = 50), hyaline, smooth, clavate or bottle-shaped, broadly rounded at the apex, truncate at the base, 0–1-septate. Chlamydospores not observed. Capturing nematodes with three-celled constricting rings, in the non-constricted state, the outer diameter is 21–32 µm (x̅ = 26 µm, n = 50), the inner diameter is 12–21 µm (x̅ = 15.5 µm, n = 50), stalks 5.5–11 µm (x̅ = 8.5µm, n = 50) long and 4–6.5 µm (x̅ = 5µm, n = 50) wide (Fig. 1).

Diagnosis

D.daliensis differs from D.hainanensis by its thinner macroconidia and shorter microconidia.

Etymology

The species name “daliensis” refers to the locality (Dali) of the type specimen.

Distribution

China, Yunnan Province, Dali City, from burned forest soil.
