ABSTRACT The systematics of ascomycete genera Apiorhynchostoma, Endoxyla and Pseudovalsaria are re-evaluated based on the comparison of cultural characteristics, teleomorph morphology and DNA sequence data. Analyses of internal transcribed spacer (ITS) of the ribosomal DNA operon and large subunit (LSU) of the nuclear ribosomal DNA gene sequences resolve Boliniales as a robustly supported lineage comprising Apiorhynchostoma, Camarops, Camaropella, Cornipulvina, Endoxyla and Pseudovalsaria. Within Boliniales, species of Endoxyla form a strongly supported lineage. Apiorhynchostoma curreyi and Pseudovalsaria ferruginea group with Cornipulvina ellipsoides. Species of Camarops are paraphyletic and comprise two clades, one of which includes Camaropella. Boliniaceae is emended, Endoxyla mallochii is described as new and Apiorhynchostoma trabicola is considered a synonym of Apiorhynchostoma altipetum. We also propose the combinations Endoxyla occulta, Endoxylina luteobasis and Jobellisia peckii. Keys to genera included in the Boliniaceae and to species of Apiocamarops, Apiorhynchostoma and Endoxyla are provided.
