Saprobic, Sexual morph: Ascomata 100–150 um diam., sphaeroid, immersed, with a papillate, erumpent to projecting ostiole. Hamathecium consisting of unbranched, septate pseudoparaphyses, filaments c. 3 um wide. Ascospores long ellipsoid, 3–septate, 19–25 x 5.5–7 um, strongly constricted at all septa, middle cells shorter than end cells, lower end cell longer than upper end cell, ends rounded, with a two–layered, 2–4 um thick gelatinous sheath, which expands to form an even larger sticky mass when the enveloping membranes are broken. Asexual morph: Undetermined.
The genus Massarina is a polyphyletic genus (Zhang et al. 2009) and many of the marine Massarina species that have been sequenced have been referred to other genera / families (Suetrong et al. 2009). Other species such as M. beaurivagea, M. cystophorae, M. lacertensis, M. mauritiana, M. phragmiticola and M. ricifera require to be recollected and sequenced to resolve their taxonomic position (Jones et al. 2009, 2015). Massarina phragmiticola has been variously referred to Lentithecium (Gnavi et al. 2014) or reduced to synonym with Lentithecium arundinaceum (Zhang et al. 2009). Massarina lacertensis has been collected in Australia on submerged wood of Rhizophora stylosa by Kohlmeyer & Volkmann–Kohlmeyer (1991). In the opinion of Aptroot (1998) in a monograph of the genus Massarina, this species does not belong to any described genus known to him. Massarina carolinensis has also been described from the culms of Juncus roemerianus but Kohlmeyer et al. (1995) do not regard this as strictly a marine species and has not be included by Jones et al. (2015).
