Triangularia was introduced by Boedijn and defined by cylindrical or clavate asci with a thickened apical ring and 2-celled smooth ascospores, with a larger, pigmented and conical to triangular upper cell and a smaller, paler or hyaline and triangular to hemisphaerical lower cell, without gelatinous appendages (Guarro & Gene 1988). However, phylogenetic analysis in Wang et al. (2019a) did not support the morphologically defined genus concept of Triangularia. Therefore, this genus is re-defined which includes morphologically diverse species. Triangularia species are usually isolated from soil and plant debris and occasional from aquatic sediments, generally from warm places (Guarro & Cano 1988).
Type species: Triangularia bambusae (J.F.H. Beyma) Boedijn.
Other accepted species: Species Fungorum – search Triangularia.
