Halomassarina Suetrong, Sakayaroj, E.B.G. Jones, Kohlm., Volkm.-Kohlm. & C.L. Schoch, in Suetrong et al., Stud. Mycol. 64: 161 (2009).

Index Fungorum number: IF 515951; Facesoffungi number: FoF 08383, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic on host. Sexual morph: Ascomata subglobose to pyriform, immersed or erumpent, ostiolate, periphysate, papillate or apapillate, clypeate, coriaceous, brown, single. Peridium of flattened, thick-walled cells, forming a textura angularis. Hamathecium of simple, rarely anastomosing pseudoparaphyses. Asci 8-spored, cylindrical to clavate, pedunculate, thick-walled, fissitunicate, with ocular chamber but without apical apparatus, I-negative. Ascospores distichous, ellipsoidal, 3-septate, hyaline, surrounded by a gelatinous sheath. Asexual morph: Unknown (adapted from Suetrong et al. 2009).

 Type species: Halomassarina thalassiae (Kohlm. & Volkm.-Kohlm.) Suetrong, Sakay., E.B.G. Jones, Kohlm., Volkm.-Kohlm. & C.L. Schoch

Notes: Halomassarina is characterised by subglobose to pyriform ascomata, cylindrical to clavate, pedunculated asci and ellipsoidal, 3-septate, hyaline ascospores surrounded by a gelatinous sheath. Halomassarina thalassiae, previously known as Massarina thalassiae was described by Kohlmeyer and Volkmann-Kohlmeyer (1987) from driftwood collected on Aldabra and Galapagos. In the phylogenetic analysis of Suetrong et al. (2009), Massarina thalassiae clustered apart from Massarina eburnea and was accommodated in the new genus Halomassarina. Halomassarina is a distinct and well-defined genus in Trematosphaeriaceae (Suetrong et al. 2009). Molecular markers available for Halomassarina are LSU, SSU and TEF-1.
