The main distinguishing character of thisclass is operculate asci, although in some taxa this character has been lost. The circumscription of the families and genericlevel delimitation in Pezizomycetes is still controversial, although several molecular phylogenetic studies have beenpublished on this group. This paper reviews 21 families of Pezizomycetes including five new families, which are introduced here, viz. Kallistoskyphaceae, Pseudombrophilaceae, Pulvinulaceae, Strobiloscyphaceae and Tarzettaceae. Moreover, this study provides a modified backbone tree based on phylogenetic analysis of five combined loci. Descriptions andillustrations of representative taxa for the families are provided from collections made in China, Thailand and the UK,herbarium material from international herbaria (FH, FLAS, H, HKAS and MA) and the literature. Pezizales separates intosix major clades. Clade 1 of Pezizales includes the families Ascobolaceae and Pezizaceae. Clade 2 is the new familyKallistoskyphaceae. Clade 3 comprises the families Caloscyphaceae, Karstenellaceae and Rhizinaceae. Clade 4 representsthe families Discinaceae, Helvellaceae, Morchellaceae, Tuberaceae and Underwoodia columnaris lineage. Clade 5includes Chorioactidaceae, Sarcoscyphaceae and Sarcosomataceae and Clade 6 comprises Ascodesmidaceae, Glaziellaceae, Otideaceae, Pseudombrophilaceae, Pulvinulaceae, Pyronemataceae, Strobiloscyphaceae and Tarzettaceae. Newsequence data belonging to ITS, LSU, SSU, TEF, RPB2 gene regions from 40 pezizalian species are provided here. Thepaper provides a working document for apothecial Pezizomycetes which can be modified as new data comes to light. It ishoped that by illustrating taxa we provide stimulation and interest in the operculate discomycetes, so that further research iscarried out on this remarkable, but poorly studied group of fungi. 展开更多
