Classification: Lindgomycetaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on submerged woody plant. Sexual morph: Ascomata scattered to clustered, semi-immersed to nearly superficial, ellipsoidal or lenticular, subglobose to globose, uniloculate, glabrous, dark brown to black, with ostiolate papilla. Peridium composed of hyaline to brown, small, thin-walled cells, sometimes poorly developed at the base. Pseudoparaphyses numerous, cellular, hyaline, septate, branched, anastomosing. Asci 8-spored bitunicate, fissitunicate, cylindrical to clavate, sessile to minutely pedicellate, rounded at the apex, with an ocular chamber. Ascospores bi- to tri-seriate, fusiform to cylindrical, straight to slightly curved, hyaline to pale brown, with a median primary septum, smooth or finely verruculose, thin-walled, usually covered with a sheath or bearing bipolar mucilaginous appendages. Senescent ascospores brown, > 3-septate (Hirayama et al. 2010). Asexual morph: Undetermined.
Notes: All Lindgomyces species have been reported from freshwater habitats. Lindgomyces was typified by Massarina ingoldiana Shearer & K.D. Hyde, which is a species complex with some strains assigned to Lindgomyces, and others to Tingoldiago (Hirayama et al. 2010). The fusiform to cylindrical ascospores with a sheath or bearing bipolar mucilaginous appendages are main characters of Lindgomyces. Lindgomyces aquaticus sp. nov. is introduced in this study.
Type species: Lindgomyces ingoldianus (Shearer & K.D. Hyde) K. Hiray., Kaz. Tanaka & Shearer
Other accepted species: Species Fungorum – search Lindgomyces.
