Melomastia is characterized by immersed, globose ascomata, 8-spored, cylindrical, J-, subapical ring asci, hyaline and 2-septate ascospores (Norphanphoun et al. 2017). Saccardo (1875) introduced Melomastia with the type M. friesii. Melomastia friesii was synonymized as M. mastoidea by Schröter (1894). Based on combined LSU, SSU and tef1 sequence data, we report Cananga odorata as a new host record for M. clematidis and Anomianthus dulcis as a new host record for M. thamplaensis in Thailand.

Type species: Melomastia mastoidea (Fr.) J. Schröt., in Chon, Krypt. -Fl. Schlesien (Breslau) 3.2(3): 320 (1894)[1908].

Other accepted species: Species Fungorum – search Melomastia.
