The order Helotiales was introduced by Nannfeldt (1932) to include fungi with cupulate apothecia covered by long cylindrical hairs. According to the previous classification system this is the largest order of Leotiomycetes and includes 27 families (Wijayawardene et al. 2018). However, according to our phylogenetic analysis this order includes 25 families/family-level clades. Previous studies (Wang et al. 2006a, b, Hustad & Miller 2011, Pärtel 2016) also confirms its polyphyletic nature within Leotiomycetes.
