Mugambi & Huhndorf (2009) established Misturatosphaeria to accommodate M. aurantiacinotata as the type species. In Misturatosphaeria, ascomata are solitary or aggregated, semi-immersed or immersed to erumpent, pyriform or globose to subglobose, ostiolar region orange or lighter. The ostiole is central, rounded, and papillate. The asci are eight-spored, bitunicate, fissitunicate, cylindrical-clavate. Ascospores are uniseriate, partially overlapping, brown to dark brown, fusiform, one to three-septate, with one of the central cells often wider than the others, with or without a mucilaginous sheath. The asexual morph has not been observed (Boonmee et al. 2019, Tennakoon et al. 2021c). Phylogenetically, Misturatosphaeria formed a distinct clade in the phylogenetic tree based on a combined LSU, SSU, ITS, tef1–α, and rpb2 sequence data. This genus includes three species (M. aurantiacinotata, M. viridibrunnea and Misturatosphaeria sp.) (Tennakoon et al. 2021c). In this study, we document Misturatosphaeria viridibrunnea (MFLUCC 24-0534), as a new host record on Dipterocarpus alatus, and the first report of asexual morph. Also, M. viridibrunnea (MFLUCC 24-0533) is recorded as a new geographical and host record on Microcos paniculata from Doi Tung National Park, Thailand.
Type species: Misturatosphaeria viridibrunnea Boonmee, Wijayaw. & K.D. Hyde.
Other accepted species: Species Fungorum – search Misturatosphaeria.
