MycoBank number: MB 515187; Index Fungorum number: IF 515187; Facesoffungi number: FoF 08267;

Saprobic on decaying wood submerged in freshwater or decayed stem in terrestrial habitats or pathogenic Sexual morph: Ascomata subglobose to globose, scattered to crowded, ostiolate. Neck short, central. Peridium composed of hyaline to pale brown, small, thin-walled cells. Hamathecium comprising numerous, filamentous, septate, branched, anastomosing, usually cellular, or trabeculate pseudoparaphyses. Asci 8-spored, fissitunicate, cylindrical to clavate, rounded at the apex, with an ocular chamber. Ascospores uni- to multi-septate, fusiform to cylindrical, hyaline to brown, usually covered with an entire sheath and/or bipolar mucilaginous appendages (adapted from Hirayama et al. 2010). Asexual morph: Coelomycetous. Conidiomata semi-immersed to superficial, single or aggregated, subglobose to ellipsoidal, ostiolate. Conidiomata wall composed of cells of textura angularis. Conidiophores lining the acervuli wall or reduced, branched, septate, smooth. Conidiogenous cells determinate, hyaline, smooth, cylindrical to sub-cylindrical, conidiogenesis holoblastic, bearing a single terminal conidium. Conidia unicellular, ellipsoidal, thin-walled, solitary, aseptate or septate, with or without apical and basal appendages, smooth, with or without an irregular mucilaginous sheath (adapted from Hyde 1993, Zhang et al. 2012b, Abdel-Aziz 2016a).

TypeLindgomyces K. Hiray., Kaz. Tanaka & Shearer.

NotesLindgomycetaceae species have been collected isolated from aquatic and terrestrial environments including ponds, rivers, lakes, and irrigation canals (Hirayama et al. 2010, Abdel- Aziz & Abdel-Wahab 2010, Raja et al. 2011, Tsang et al. 2014, Hyde et al. 2016), except for Hongkongmyces which occurred on a human foot with suppurative granulomatous (Tsang et al. 2014). Shearer et al. (2009) provided molecular data and analyses of nine taxa in Lindgomycetaceae, and placed Massarina ingoldiana, Massariosphaeria typhicola, and Lophiostoma breviappendiculatum in Lindgomycetaceae. Similar studies resolved this (Abdel-Aziz 2016a, Raja et al. 2017). Neomassariosphaeria was earlier transferred to Lindgomycetaceae to accommodate Massariosphaeria typhicola (Ariyawansa et al. 2015a). However, this was not accepted by Dong et al. (2020) who retained Neomassariosphaeria in Amniculicolaceae and introduced a new genus Aquimassariosphaeria in Lindgomycetaceae. The relationships in this family have not been well-resolved. Additional morphological and molecular data are needed for this group.
