Profile of Bionectriaceae, Calcarisporiaceae, Hypocreaceae, Nectriaceae, Tilachlidiaceae, Ijuhyaceae fam. nov., Stromatonectriaceae fam. nov. and Xanthonectriaceae fam. nov

This paper provides outlines for Bionectriaceae , Calcarisporiaceae , Hypocreaceae , Nectriaceae , Tilachlidiaceae , Ijuhyaceae , Stromatonectriaceae and Xanthonectriaceae with taxonomic treatments. We provide up-to-date DNA sequence-based phylogenies including combined gene analysis of ITS, LSU, rpb2 , tef1 and tub2 for Hypocreales and accept 17 families. Three new families and 12 new species are introduced with descriptions and illustrations, while 13 new records and one new species combination are provided. Here we mainly detail the taxonomy of Bionectriaceae , Hypocreaceae , Nectriaceae and Tilachlidiaceae , Ijuhyaceae fam. nov., Stromatonectriaceae fam. nov. and Xanthonectriaceae fam. nov. are introduced in this study based on phenotypic and molecular analyses. For each family we provide a list of accepted genera, the taxonomic history, morphological descriptions, taxonomic placement based on DNA sequence data and illustrate the type genus. Representatives of each family are illustrated based on the type herbarium material or fresh specimens where available, or provide relevant references. Notes on ecological and economic importance of the families are also given.
