Abstract

The Nitschkiaceae has been placed in the Coronophorales or the Sordariales in recent years. Most recently it was accepted in the Coronophorales and placed in the Hypocreomycetidae based on sequence data from large subunit nrDNA. To confirm and corroborate the taxonomic placement and monophyly of the Coronophorales, additional taxa representing the diversity of the group were targeted for phylogenetic analysis using partial sequences of the large subunit nrDNA (LSU). Based on molecular data, the Coronophorales is found to be monophyletic and its placement in the Hypocreomycetidae is maintained. The order is a coherent group with morphologies that include superficial, often turbinate, often collabent ascomata that may or may not contain a quellkorper and asci that are often stipitate and at times polysporous. Three species with accepted Nitschkia names, together with Fracchiaea broomeiana and Acanthonitschkea argentinensis, comprise the paraphyletic nitschkiaceous complex. Two new families, Chaetosphaerellaceae and Scortechiniaceae fams nov., are described for the clades containing Chaetosphaerella and Crassochaeta and the taxa having a quellkorper (Euacanthe, Neofracchiaea and Scortechinia) respectively. The Bertiaceae is accepted for the clade containing Bertia species. Three new species are described: Bertia tropicalis, Lasiobertia portoricensis, and Nitschkia meniscoidea spp. nov.
