Type species: Taiwanascus tetrasporus Sivan. & H.S. Chang, Mycol. Res. 101(2): 176 (1997)
Notes: Taiwanascus was introduced by Sivanesan & Chang (1997) for T. tetrasporus. Rajeshkumar & Rossman (2013) subsequently introduced second species, T. samuelsii, from India. These species have cleistothecial ascomata with special branched setae, but the former has fusiform ascospores and the latter has ellipsoidal (Sivanesan & Chang 1997, Rajeshkumar & Rossman 2013). There is no sequence data available for this genus (copied from Huang et al. 2021).
