Pseudopaucispora was introduced to accommodate P. brunneospora A. Hashim., K. Hiray. & Kaz. Tanaka, with pseudopycnidia and small, brown ascospores (Hashimoto et al. 2018). This genus is somewhat similar to Paucispora (Thambugala et al. 2015). Pseudopaucispora differs from Paucispora in having a single zone ascomatal peridium and an ascus with a short pedicel, whereas Paucispora has two zones in the peridium and an ascus with a relatively long pedicel (Thambugala et al. 2015, Hashimoto et al. 2018). 

Type species: Pseudopaucispora brunneospora A. Hashim., K. Hiray. & Kaz. Tanaka, in Hashimoto, Hirayama, Takahashi, Matsumura, Okada, Chen, Huang, Kakishima, Ono & Tanaka, Stud. Mycol. 90: 179 (2018).

Other accepted species: Species Fungorum – search Pseudopaucispora.
