Meliola Fr., Syst. orb. veg. (Lundae) 1: 111(1825)
MycoBank number: MB 3100; Index Fungorum number: IF 3100; Facesoffungi number: FoF 00740; 1694 morphological species (Species Fungorum 2020, Zeng et al. 2017), 20 species with sequence data.
Type species – Meliola nidulans (Schwein.) Cooke
Notes – Meliola is the largest genus in Meliolaceae, which comprises more than 70% of species in the family. Members of this genus typically have hyphal setae and globose ascomata. Meliola telosmae is illustrated in this entry (Fig. 162). Meliola telosmae differs from M. clerodendricola in having longer appressoria and setae, and thinner, light brown ascospores. Therefore, we assign this new collection as a reference specimen of M. telosmae with sequence data provided.
