Description.
Sexual morph: Undetermined. Asexual morph: Setae numerous, erect, arising from radially lobed basal cells, straight or flexuous, unbranched, single, thick-walled, verrucose, dark brown, 130–189 μm long, 5.4–8.6 μm wide at the base, tapering to apointed apex, or arising from a dark brown, swollen, radially lobed cell, 12.9–22.8 μm in diameter. Conidiophores macronematous, sometimes setiform, single, straight, partly verrucose, smooth-walled, 21.9–60.7 μm long, 3.2–5.2 μm wide (av. = 39 μm × 4.2, n = 11), sometimes branched at the apical region, subhyaline to pale yellow, paler towards a pointed apex. Conidiogenous cells monoblastic to polyblastic, integrated, terminal, geniculate, cylindrical, hyaline to subhyaline, smooth, 10–12 × 2.4–5.2 μm (av. = 11.39 ± 1.05 × 6.00 ± 0.87 μm). Separating cells ovoid or fusiform, thin-walled, smooth, hyaline to subhyaline, 1 - denticulate at each end, 8.9–11.9 µm (av. = 10.4 μm, n = 25) long, 3.2–4.6 µm (av. = 3.9 μm, n = 25) wide in the broadest part. Conidia acrogenous, simple, dry, straight, smooth, thin-walled, turbinate to obpyriform, rostrate to pointed at proximal end, rounded at distal end, hyaline to subhyaline, 17.8–23.7 µm long, 3.9–8.1 µm wide (av. = 20.28 × 6.25 μm, n = 25) in the broadest part.

Notes.
Existing strains of Beltraniella fertilis ( MFLUCC 17-2136 , MFLUCC 17-2137 , MFLUCC 17-2138 , MFLUCC 19-0487 , and MFLUCC 20-0119 ) and our isolate ( SAUCC 2153-2 ) clustered with good support ( ML = 86 %, BI = 0.9) in the phylogenetic tree. A comparison of nucleotides shows the ITS and LSU loci of our isolate are identical to those of Be. fertilis ( MFLUCC 17-2136 , MFLUCC 17-2137 , MFLUCC 17-2138 , and MFLUCC 19-0487 ). Our isolate is similar to Be. fertilis in its setae, conidiophores, and conidia. However, the conidial size of MFLUCC 20-0119 is smaller than that of the others. No median transverse band of lighter pigment was observed in the conidia of our isolate and MFLUCC 20-0119 . These morphological variations are likely caused by differences in environmental conditions ( Francisco et al. 2019). Based on morphological characteristics and phylogenetic analysis, this study is the first report of Be. fertilis in China ( Heredia et al. 2002; Lin et al. 2017 b; Perera et al. 2020; Yasanthika et al. 2020).
