Type species – Bertiella macrospora (Sacc.) Sacc. & Traverso, Syll. fung. (Abellini) 19: 147 (1910).
≡ Bertia macrospora Sacc., Michelia 2(no. 8): 452 (1882).
Notes – Bertiella is characterised by superficial ascomata, cylindro-clavate asci and hyaline, 1-septate ascospores that may become 3-septate and pale brown when senescent. Bertiella has been placed in Massarina (as M. macrospora). and Lophiostoma (as L. bertiellum by Eriksson & Yue (1986) and Hyde et al. (2002), respectively. Mugambi & Huhndorf (2009a) from molecular evidence confirmed placement of Bertiella in Melanommataceae. Two species B. ellipsoidea and B. macrospora have been confirmed with morphological characters and molecular evidence. Hashimoto et al. (2017a) proposed Melanommataceae should be restricted to the type genus Melanomma, and placed other Melanommataceae taxa (sensu lato) in an uncertain place in Melanommataceae, including Bertiella. Tian et al. (2015) retained Bertiella in Melanommataceae pending molecular data of new epitypification from Italy which corresponds with Jaklitsch & Voglmayr (2017) and Wanasinghe et al. (2018c).
