Hysteriales is monotypic. Fungi classified in Hysteriaceae (Hysteriales), Mytilinidiaceae (Mytilinidiales), and Gloniaceae (Gloniales), possess persistent, carbonaceous ascomata that characteristically dehisce by a longitudinal suture. Molecular data supports the inclusion of all three families within Pleosporomycetidae (Schoch et al. 2006, Boehm et al. 2009a, b, Mugambi & Huhndorf 2009b, Hyde et al. 2013) and in three separate orders (Boehm et al. 2009a, b, Jayasiri et al. 2018). In Hysteriales ascomata are thick-walled, navicular, characteristically dehiscing by an invaginated slit or sulcus (Zogg 1962). In Mytilinidiaceae, taxa possess strongly laterally compressed, thin-walled conchate ascomata, reminiscent of miniature bivalve molluscs. Taxa belonging to Gloniaceae, have dichotomously branched, laterally anastomosed pseudothecia, that form radiating pseudo-stellate composites and dehisce by an inconspicuous, longitudinal, but evaginated slit (Boehm et al. 2009a, b). Coniosporium was previously classified in Hysteriaceae (Wijayawardene et al. 2018), however after DNA sequence analyses, it has been referred to Dothideomycetes genera, incertae sedis (Tsuneda et al. 2018). The divergence time for Hysteriales is estimated as 109 MYA (stem age)
