The Genera of Fungi - G 4: and .

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, and , which are respectively epi- and neotypified. The genus is typified by , which has a karstenula-like sexual morph, and phoma-like synasexual morph. Furthermore, and are introduced as new camarosporium-like genera, while is introduced as a new phoma-like genus. is introduced as a new family to accommodate and . , which is typified by , is shown to produce dothichiza- and hormonema-like synasexual morphs in culture, and 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.
