Jahnulales was introduced in Dothideomycetes based on phylogenetic analysis of SSU nrDNA sequence data from Aliquandostipite, Jahnula and Patescospora (Pang et al. 2002). This order is phylogenetically related to the Dothideales, Patellariales and Pleosporales (Campbell et al. 2007). Most Jahnulales species occur on rotting or soft submerged corticated or decorticated wood (Huang et al. 2018). Phylogenetic analyses (Fig. 35) indicate that Jahnulales comprises two major lineages which are designated as two different families (Aliquandostipitaceae and Manglicolaceae). Jahnula forms as paraphyletic within Aliquandostipitaceae. The divergence time for Jahnulales is estimated as 204 MYA (stem age, Hongsanan et al. 2020).

Accepted families: Aliquandostipitaceae, Manglicolaceae.
