Junewangiaceae was established to accommodate a single genus Junewangia, characterized by macronematous, cylindrical conidiophores, monoblastic conidiogenous cells with narrow or flaring collarette, and oval, ellipsoidal to spherical conidia (Xia et al. 2017). Other two genera, Dictyosporella and Sporidesmiella, were later included in the family based on multigene analyses (Luo et al. 2019). Sporidesmiella differs from other genera in having long conidiophores without collarette, and cuneate to obovoid conidia with fewer septa (Kirk 1982, Luo et al. 2019). Dictyosporella and Junewangia have muriform conidia, but the latter differs in having long conidiophores (Ariyawansa et al. 2015, Xia et al. 2017, Song et al. 2018a). Hyde et al. (2020) referred Sporidesmiella to Diaporthomycetidae genera incertae sedis because Sporidesmiella clustered in a separated clade with Junewangiaceae. However, in our phylogenetic analysis, the three genera Dictyosporella, Junewangia and Sporidesmiella constitute a well-supported clade with strong ML and BYPP bootstrap support, which is accordant with Luo et al. (2019). Thus, we accept these three genera in Junewangiaceae. The family placement of Junewangiaceae is undetermined and referred to Diaporthomycetidae genera incertae sedis in this study.
