Tetraploa was reinstated, suppressing Tetraplosphaeria Kaz. Tanaka & K. Hiray. by Hyde et al. (2013). Hyde et al. (2020b) doubted that Dwibahubeeja N. Srivast. et al. was a synonym of Tetraploa because of the similarities of T. dwibahubeeja Rajeshkumar et al. and D. indica N. Srivast. et al. (type). However, this cannot be resolved until sequence data of D. indica is available.

Tetraploa is similar to other genera in Tetraplosphaeriaceae in having conidia with several setose appendages, but differs by its globose ascomata, narrowly fusiform ascospores surrounded by a narrow mucilaginous appendage-like sheath and cylindrical, euseptate conidia with setose appendages (Hyde et al. 2013).

The freshwater species T. scheueri Kaz. Tanaka & K. Hiray. was proposed by Hyde et al. (2013) to replace Tetraplosphaeria tetraploa (Scheuer) Kaz. Tanaka & K. Hiray. The asexual morph of T. scheueri was reported as T. aristata Berk. & Broome based on cultural methods (Scheuer 1991). However, Tanaka et al. (2009) considered T. aristata to be a species-complex composed of phylogenetically diverse lineages. Thus, the identification of T. aristata should be re-evaluated (Tanaka et al. 2009). In our phylogenetic analysis, two putative strains T. aristata (CBS 996.70) and T. scheueri (CY112) cluster together and there are two nucleotide differences in ITS sequence data, which probably supports the conclusion of Scheuer (1991). However, the real identities of two strains are unknown because their morphology are unavailable (Tanaka et al. 2009; Rodrigues et al. 2011).

Type species: Tetraploa aristata Berk. & Broome.

Other accepted species: Species Fungorum – search Tetraploa.
