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 " Drechslerella daliensis " refers to the locality (Dali) of the type specimen.

Distribution

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