Junewangia was introduced to accommodate the species having macronematous, mononematous conidiophores with slightly flaring collarette and percurrent proliferations, and oval to subspherical conidia with several oblique septa and a protuberant, truncate basal cell (Baker et al. 2002). Xia et al. (2017) provided sequence data for three species, i.e. J. lamma, J. queenslandica and J. sphaerospora (type), and establish a new family Junewangiaceae to accommodate Junewangia. Except for J. obliqua, all Junewangia species have sequence data in GenBank. Junewangia is shown to be polyphyletic as Junewangia species cluster with Dictyosporella hydei and D. ellipsoidea in two separated clades. The polyphyletic nature of Junewangia needs to be resolved with more collections and DNA sequence data. We introduce a new species in Junewangia, which was collected from submerged wood in freshwater in Thailand.
Type species: Junewangia sphaerospora W.A. Baker & Morgan-Jones, Mycotaxon 81: 312 (2002).
