Abstract
The current paper represents the fourth contribution in the Genera of Fungi series, linking type species of fungal genera to their morphology and DNA sequence data. The present paper focuses on two genera of microfungi, Camarosporium and Dothiora, which are respectively epi- and neotypified. The genus Camarosporium is typified by C. quaternatum, which has a karstenula-like sexual morph, and phoma-like synasexual morph. Furthermore, Camarosporomyces, Foliophoma and Hazslinszkyomyces are introduced as new camarosporium-like genera, while Querciphoma is introduced as a new phoma-like genus. Libertasomycetaceae is introduced as a new family to accommodate Libertasomyces and Neoplatysporoides. Dothiora, which is typified by D. pyrenophora, is shown to produce dothichiza- and hormonema-like synasexual morphs in culture, and D. cactacearum is introduced as a new species. In addition to their typification, ex-type cultures have been deposited in the Westerdijk Fungal Biodiversity Institute (CBS Culture Collection), and species-specific DNA barcodes in GenBank. Authors interested in contributing accounts of individual genera to larger multi-authored papers in this series should contact the associate editors listed on the List of Protected Generic Names for Fungi.
