Pseudothielavia X. W. Wang & Houbraken

Notes.

The genus Pseudothielavia was initially proposed by Wang and Houbraken (2019), to place Coniothyrium terricola , which is initially isolated from soil habitat. In recent years several species were introduced in this genus and currently four species epithets are listed in MycoBank (Accession date: March 10, 2025) for Pseudothielavia . Ascomata of these species are solitary to aggregated, globose or subglobose, superficial or submerged. They are typically non-ostiolate, though some species develop an ostiole at maturity. Peridium is brown, composed of textura epidermoidea, and may appear semi-translucent or translucent. Asci are clavate to pyriform, eight-spored and evanescent. Ascospores are 1 - celled, olivaceous brown at maturity, smooth-walled, fusiform in shape and possess an apical, oblique or lateral germ pore ( Wang et al. 2019). Species reported for Pseudothielavia are widely distributed and have been reported from Chile, China, Egypt, Japan, Papua New Guinea, and USA mainly from soil habitats ( Wang et al. 2019; Zhang et al. 2021; Noguchi et al. 2022; Hussien et al. 2023).
