Classification: Tetraplosphaeriaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on decaying or submerged bamboo in freshwater or terrestrial habitats. Sexual morph: Ascomata scattered to gregarious, immersed under the epidermis, subglobose, uniloculate, glabrous, with or without a short neck, periphysate. Peridium rim-like at sides, composed of vertically orientated rectangular to cylindrical, hyaline, hyphoid cells, poorly developed at the base. Pseudoparaphyses numerous, trabeculate, narrow, hyaline, indistinctly septate, branched. Asci bitunicate, fissitunicate, cylindrical to clavate, with rounded apex and short pedicellate. Ascospores 8-spored, fusiform, with rounded ends, 1-septate, hyaline, smooth, with an entire sheath (Tanaka et al. 2009). Asexual morph: Hyphomycetous. Conidiophores absent. Conidiogenous cells monoblastic. Conidia ovoid to obpyriform, brown, verrucose at the base, composed of three columns, with three setose appendages at the apex (Tanaka et al. 2009).

Notes: Triplosphaeria was introduced for massarina-like ascomycetes and tetraploa-like asexual morphs (Tanaka et al. 2009). Triplosphaeria is similar to Tetraploa in overall morphology of conidia, but differs by its hemispherical ascomata with flattened base (Tanaka et al. 2009; Hyde et al. 2013). Phylogeny clearly separates them as two distinct genera (Tanaka et al. 2009; Hyde et al. 2020b) Triplosphaeria acuta Kaz. Tanaka & K. Hiray. is the only species collected from freshwater habitats (Tanaka et al. 2009).

Type species: Triplosphaeria maxima Kaz. Tanaka & K. Hiray.

Other accepted species: Species Fungorum – search Triplosphaeria.
