MycoBank number: MB 811900; Index Fungorum number: IF 811900; Facesoffungi number: FoF 08827.
Valsariales was introduced by Jaklitsch et al. (2015) based on multi-gene phylogeny analyses to accommodate the sigle family Valsariaceae. Valsariales species have perithecioid ascomata, immersed in eu- or pseudostromata, bitunicate asci, without obvious fissitunicate dehiscence and dark brown, bicelled ascospores. Member of Valsariales have a worldwide distribution on various substrates as saprobes, plant pathogens or necrotrophs (Ju et al. 1996; Jaklitsch et al. 2015). There are only three genera with molecular data. Our phylogenetic analyses generated from ITS, LSU, SSU and tef1 sequence data (Fig. 87) indicate that the three genera cluster with high bootstrap support (100% ML, 1.0 PP), and each genus is well-resolved. The divergence time for Valsariales is estimated as 224 MYA (stem age, Hongsanan et al. 2020).
Accepted families: Valsariaceae.
