Acrospermales was established by Minter et al. (2007) as an incertae sedis taxon. It was placed in an independent lineage that was closely related both Dothideomycetes and Arthoniomycetes (Stenroos et al. 2010). Later, Pang et al. (2013) assigned Acrospermales to Dothideomycetes based on phylogenetic analysis of partial SSU, LSU, and tef1-α sequences. Acrospermales represents one of the least studied orders of Dothideomycetes and includes epiphytic, saprotrophic, fungicolous, lichenicolous, and bryophilous species. The ordinal placement of Acrospermaceae has been disputed for a long time (Hudson et al. 2019, Darmostuk & Flakus 2024). In this study, we introduced a new family Novolignincolaceae to accommodate the new genus Novolignincola based on the specimens collected from dead wood in Thailand.
