Neolindgomyces

Neolindgomyces Jayasiri, E.B.G. Jones & K.D. Hyde

Index Fungorum number: IF555555

 

Saprobic on Pandanus sp. or submerged wood. Sexual morph: Ascomata scattered to gregarious, immersed, depressed globose or conical with flattened base, dark brown to black, coriaceous, with a small clypeus ostiole. Ostiole with a pore-like opening, central, with a reduced crest, with periphyses made up of lightly pigmented, pseudoparenchymatous cells. Peridium composed of dark brown to black, somewhat flattened cells of textura angularis, fusing and indistinguishable from the host tissues, with inner stratum comprising hyaline cell layers of textura angularis. Pseudoparaphyses numerous, trabeculate, filamentous, hyaline, septate, branched. Asci 8-spored, bitunicate, fissitunicate, cylindric-clavate, short pedicellate, apex rounded with a minute ocular chamber or inconspicuous apical thickening. Ascospores uni- to bi-seriate, overlapping, hyaline, cylindrical or fusiform with narrow, acute ends, septate, smooth-walled, with a mucilaginous sheath. Asexual morph: Undetermined. (Description from Dong et al. 2020)

 

Type species: Neolindgomyces pandani Jayasiri, E.B.G. Jones & K.D. Hyde

 

Notes: Neolindgomyces was introduced for N. pandani and a known species Quintaria submersa K.D. Hyde & Goh collected from freshwater habitats (Hyde and Goh 1999; Jayasiri et al. 2019). Neolindgomyces is distinctive in Lindgomycetaceae by its carbonaceous peridium and presence of clypeus (Jayasiri et al. 2019). It formed a basal clade in the family with high bootstrap support (Jayasiri et al. 2019) but showed low support in the phylogenetic analysis of Dong et al. 2020. (Notes from Dong et al. 2020)
