Type species – Navicella julii Fabre, Annls Sci. Nat., Bot., sér. 6 9: 96 (1879).
Notes – Barr (1990a) reappraised the type species Navicella julii and described the genus in having immersed to erumpent ascomata, clavate or cylindrical asci, trabeculate pseudoparaphyses and distoseptate ascospores. Navicella was considered to be closely related to Lophiostomataceae (Holm & Holm 1988, Thambugala et al. 2015b) based on similar morphological characters, while Navicella has conspicuously thickened, distoseptate ascospores and lenticular lumina (Eriksson 1981, Thambugala et al. 2015b). Navicella was suggested to be a member of Melanommataceae based on the similarities in having superficial globose to subglobose, coriaceous ascomata with long, trabeculate pseudoparaphyses and brown ascospores, but differs from other genera of Melanommataceae in having ascospores with euseptate primary septa, while in others are distoseptate, with hyaline appendages at each end (Ariyawansa et al. 2014e, Tian et al. 2015).
