≡ Massarina thalassiae Kohlm. & Volkm.-Kohlm., 1987a, Canad. J. Bot., 65: 575.

Sexual morph: saprobic, ascomata: 270-425 x 240-335 µm, sub-globose to pyriform, immersed in the substrate, ostiolate, periphysate, epapillate or short papillate, clypeate, coriaceous, brown. Necks: 140-150 x 150-180 µm, ostiolar canal filled with short hyaline periphyses. Peridium: 12-16 µm thick, composed of flattened thick-walled cells. Pseudoparaphyses: 1.5-2 µm wide, simple, rarely anastomosing, septate. Asci: 100-160 x 28-34 µm, 8-spored, cylindrical to clavate, short pedunculate, thick-walled, fissitunicate, with a distinct ocular chamber, arising from a basal ascogenous tissue. Ascospores: 34-49 x 9-13 µm, distichously in the ascus, ellipsoidal, at first 1-septate, later 3-septate, constricted at the central septum, surrounded by a gelatinous sheath, senescent ascospores become brownish and verruculose. Asexual morph: Undetermined (Description: Based on Kohlmeyer & Volkmann-Kohlmeyer (1987)).

NOTES: The genus Massarina has been shown to be polyphyletic and many species educed to synonymy by Hyde & Aptroot (1998). Massarina thalassiae was described by Kohlmeyer & Volkmann-Kohlmeyer (1987) from driftwood collected on Aldabra and Galapagos. However, M. thalassiae in a multigene analysis did not group with Massarina eburnea and was therefore transferred to a new genus Halomassarina in the family Trematosphaeriaceae (Suetrong et al. 2009). The family Trematosphaeriaceae was validated by Suetrong et al. (2011). Halomassarina thalassiae is widely collected on a variety of intertidal mangrove timbers with many records from India (Borse et al. 2012).
