The present study introduces two new genera, 14 new species, five new combinations and 12 interesting host and/or geographical records. A majority of the fungi are Ascomycetes, but the study also includes a Basidiomycete, Xerocomellus fulvus described from Pakistan. Under single name nomenclature Zeuctomorpha arecae is reduced to synonymy under Acroconidiellina arecae (Sympoventuriaceae, Venturiales, Dothideomycetes). Based on morphology and phylogenetic affinities, Wojnowicia dactylidis, W. lonicerae and W. spartii are moved to the genus Wojnowiciella (Phaeosphaeriaceae, Pleosporales, Dothideomycetes) and Zalerion arboricola is now accommodated in Lophium (Mytilinidiaceae, Mytilinidiales, Dothideomycetes). Novel genera include: Alfariacladiella gen. nov. (Stachybotryaceae, Hypocreales, Sordariomycetes) with A. spartii sp. nov. as type species, and Calvolachnella gen. nov. (Chaetosphaeriales, Sordariomycetes) to accommodate Calvolachnella guaviyuensis comb. nov., previously included in Pseudolachnella. Novel species include: Castanediella hyalopenicillata from leaf litter (USA), C. malaysiana on Eucalyptus brassiana (Malaysia) (Xylariales, Sordariomycetes), Morchella pakistanica (Morchellaceae, Pezizales, Pezizomycetes) on loamy soil (Pakistan), Muriphaeosphaeria viburni (Phaeosphaeriaceae, Pleosporales, Dothideomycetes) on twigs of Viburnum lantana (Serbia), Phyllosticta aucubae-japonicae (Phyllostictaceae, Botryosphaeriales, Dothideomycetes) on fruit of Aucuba japonica (Japan), Wojnowiciella leptocarpi (Phaeosphaeriaceae, Pleosporales, Dothideomycetes) on stems of Leptocarpus sp. (Australia), and Xylomelasma shoalensis (Sordariomycetes) on a dead branch (USA). New species from Germany include: Neosetophoma lunariae and Phaeosphaeria lunariae (Phaeosphaeriaceae, Pleosporales, Dothideomycetes) on seeds of Lunaria annua, Patellaria quercus (Patellariaceae, Patellariales, Dothideomycetes) on twigs of Quercus sp., Rhinocladiella coryli on stems of Corylus avellana and Rhinocladiella quercus (Herpotrichiellaceae, Chaetothyriales, Eurotiomycetes) on twigs of Quercus robur. Ramularia eucalypti (Mycosphaerellaceae, Capnodiales, Dothideomycetes) is reported on leaves of Citrus maxima from Italy, Beltrania rhombica (Beltraniaceae, Xylariales, Sordariomycetes) on leaves of Acacia sp. from Malaysia and Myrmecridium spartii (Myrmecridiaceae, Myrmecridiales, Sodariomycetes) on Sarothamnus scoparius from Serbia. New reports from Australia include: Dothiora ceratoniae (Dothideaceae, Dothideales, Dothideomycetes) on leaves of Eucalyptus sp., Readeriella dimorphospora (Teratosphaeriaceae, Capnodiales, Dothideomycetes) on Eucalyptus sp., Vermiculariopsiella dichapetali (Sordariomycetes) on leaves of Grevillea sp. and Acacia glaucoptera, and Verrucoconiothyrium nitidae (Montagnulaceae, Pleosporales, Dothideomycetes), on leaves of Acacia leprosa var. graveolens. New reports from La Reunion (France) include: Botryosphaeria agaves (Botryosphaeriaceae, Botryosphaeriales, Dothideomycetes) on branches of Agave sp., Chrysofolia colombiana (Cryphonectriaceae, Diaporthales, Sordariomycetes) on leaves of Syzygium jambos, Colletotrichum karstii (Glomerellaceae, Glomerellales, Sordariomycetes) on leaves of Acacia heterophylla, Epicoccum sorghinum (Didymellaceae, Pleosporales, Dothideomycetes) on leaves of Paspalum sp. and Helminthosporium velutinum (Massarinaceae, Pleosporales, Dothideomycetes) on branches of Stoebia sp. Finally, an epitype is designated for Tracylla aristata (Sordariomycetes) on Eucalyptus regnans (Australia).
