Saprobic on submerged mangrove wood and culms of salt marsh plants in marine habitats. Sexual morph: Ascomata solitary, immersed, fusiform to ellipsoidal, brown, coriaceous, ostiolate. Paraphyses persistent, simple, septate. Asci unitunicate, 4-spored, cylindrical, short pedicellate, thick-walled, with an ocular chamber and ring. Ascospores uni- to biseriate, fusiform, hyaline, muriform, distoseptate, outer wall very thick. Asexual morph: Undetermined (adapted from Jones et al. 2015).
Type species: Lautospora gigantea K.D. Hyde & E.B.G. Jones, Bot. Mar. 32(3): 479 (1989)
Notes: Lautospora species can be distinguished by their immersed ascomata, 4-spored, unitunicate asci with an ocular chamber and ring, cellular paraphyses and large ascospores which are muriform, hyaline and thick-walled (Hyde & Jones 1989). Kohlmeyer et al. (1995) introduced Lautosporaceae to include this genus and assigned it to Ascomycotina family incertae sedis. More taxon sampling and DNA sequencing are recommended for this genus, including the type L. gigantea to confirm its phylogenetic placement. Lautospora simillima is a second species assigned to the genus, occurring very soft culms of Juncus roemerianus. It is an obligate marine fungus, with its ascomata occurring singly, or at the most, in pairs at the base of the culms, between 3 and 12 cm above the rhizome. No asexual morph has been reported for this species (Kohlmeyer et al. 1995, Wijayawardene et al. 2017a).
