Classification: Ustilaginomycotina, Basidiomycota, Dikarya, Fungi.

Class of mesophilic, heat resistant, and osmotolerant basidiomycetes with slow hyphal growth and high phenotypic variability. Characteristically, triangular-shaped chlamydospores are distally produced on coiled hyphae. Sympodial, ovoid conidia are produced. Relatively simple septal pores, without thickened septum membranes. Parenthesomes, forming distinct septal pore caps are absent, but low contrasted elements indicate non-membranous structures around the pore openings and within the pore. Based on the analysis of 38 protein-coding genes, orthology analysis, and septal pore type analysis, this class is placed within the Ustilaginomycotina (Witfeld et al. 2023).

Life modes and distribution: From soil, associated with Pinus resinosa. Known from Nova Scotia (Witfeld et al. 2023).

Notes: Witfeld et al. (2023) introduced Peribolospora Witfeld et al. (type: P. baueri Witfeld et al.) and showed that this genus has a distinct phylogenetic lineage in Ustilaginomycotina. Hence, they introduced new family (Peribolosporaceae), order (Peribolosporales) and class (Peribolosporomycetes).
