Albifimbria verrucaria (Albertini & Schweinitz) L. Lombard & Crous, Persoonia 36: 177 (2016) Fig. 5

Facesoffungi number: FoF 04192

Isolated from soil. Sexual morph: Undetermined. Asexual morph: coelomycetous. Colonies olive to greenish white, effuse, flat, with alternating circular sporulating and non-sporulating zones, 3–5 cm diam. in one week on PDA at 25 ºC. Conidiomata sporodochial, sessile, often confluent, at first green, later becoming olive with white margin, without setae. Conidiophores short, septate, penicillately branched, smooth, hyaline. Conidiogenous cells 7–14 × 1–2 μm (av. 11.5 × 1.6 μm), with several oil vacuoles. Conidia ellipsoid or lemon-shaped, subhyaline to hyaline, with several oil vacuoles, 5–7 × 2–3 μm (av. 6.7 × 2.7 μm), with funnel-shaped mucilaginous pad at base of conidia.

Notes: Phylogenetic analysis indicate that our strains should be Albifimbria verrucaria with 92% ( MP) and 93% ( ML) bootstrap support. The morphological characters of our six strains are consistent with A. verrucaria in conidia and conidiogenous cells ( Lombard et al. 2016, Tulloch 1972). This is also the first report of A. verrucaria in China.
