Sydowia 67: 81–118

Fungal Systematics and Evolution (FUSE) is introduced as a new series to expedite the publication of issues relating to the epitypification of formerly described species, report new sexual-asexual connections, the merging of sexual and asexual gen­era following the end of dual nomenclature, and to describe species or note interesting observations regarding fungi. This first paper includes 18 new combinations, 13 new species, three new genera and one new family. All taxa are ascomycetes, except one novel species, which is a basidiomycete. Based on its acervular conidioma, Septoria capensis is allocated to the genus Ac­ervuloseptoria (Mycosphaerellaceae, Capnodiales, Dothideomycetes). Cheirospora botryospora is shown to have a Phialophora synasexual morph, and to belong to the Helotiales (Leotiomycetes). The genus Circinotrichum (Xylariaceae, Xylariales) is shown to be paraphyletic, and in need of revision. Dictyochaeta triseptata (Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetes) is reported on Eucalyptus twigs from Malaysia, and shown to have a microconidial morph. Pseudodinemasporium fabiforme (Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetes) is reported from leaf spots on Acacia mangium from Malaysia, and Sclerostagonospora cycadis (Phaeosphaeriaceae, Pleosporales, Dothideomycetes) on leaves of Dioscorea composita from Mexico. Novel taxa include: Asperisporium caricicola (Mycosphaerellaceae, Capnodiales, Dothideomycetes) from Carica papaya (Fiji), Coniella peruensis (Schizoparmaceae, Diaporthales, Sordariomycetes) from soil (Peru), Curreya acacia (Cucurbitariaceae, Ple­osporales, Dothideomycetes) from Acacia mangium (Malaysia), Verrucoconiothyrium nitidae gen. nov. (Didymosphaeriaceae, Pleosporales, Dothideomycetes) from Proteaceae (South Africa), Cyphellophoriella pruni gen. et sp. nov. (Chaetothyriaceae, Chaetothyriales, Eurotiomycetes) from Prunus leaves (USA), Mycotribulus indonesiae (Physalacriaceae, Agaricales) from Euca­lyptus leaves (Indonesia), Myrmecridium spartii (Myrmecridiaceae, Myrmecridiales, Sordariomycetes) and Diaporthe spartini­cola (Diaporthaceae, Diaporthales, Sordariomycetes) from Spartium junceum (Spain), Neodevriesia poagena (Neodevriesiaceae, Capnodiales, Dothideomycetes) on stems of Poa sp. (the Netherlands). Novel taxa from Germany include: Dothiorella ulmacea (Botryosphaeriaceae, Botryosphaeriales, Dothideomycetes) from Ulmus laevis, Eleutheromyces pseudosubulatus (incertae sedis, Helotiales) from Lactarius scrobiculatus, Paracamarosporium fagi (Didymosphaeriaceae, Pleosporales, Dothideomycetes) from Fagus sylvatica, Phaeoisaria loranthacearum (incertae sedis, Sordariomycetes) from Loranthus europaeus, and Flammocladiella aceris gen. et sp. nov. (Flammocladiellaceae fam. nov., Hypocreales) from Acer platanoides. An epitype is designated for Phomato­spora striatigera (incertae sedis, Sordariomycetes) from Typha angustifolia (France).

Keywords: biodiversity, ITS barcodes, multi-gene phylogeny, systematics, typification.
