Bertiella (Sacc.) Sacc

Notes.

Bertiella was established by Saccardo and Sydow (1899) to include B. macrospora as the type species. The species have superficial ascomata, cylindrical-clavate asci and hyaline, 1 - septate (when immature) and pale brown, 3 - septate (when mature) ascospores (Tian et al. 2015; Hongsanan et al. 2020). To the present time, there are six Bertiella species in Species Fungorum (2024). Of them, molecular data are available only for three species. Bertiella species have been reported from six different plant families, Cyrillaceae, Fagaceae, Lauraceae, Moraceae, Salicaceae and Ulmaceae (Fig. 10).
