The Colletotrichum boninense species complex
TLDR
Seven of the new species are only known from New Zealand, perhaps reflecting a sampling bias, and the new combination C. phyllanthi was made, and C. dracaenae Petch was epitypified and the name replaced with C. petchii. Expand
Fungal Planet description sheets: 214–280
Novel species of microfungi described in the present study include the following from South Africa: Cercosporella dolichandrae from Dolichandra unguiscati, Seiridium podocarpi from Podocarpus… Expand

Novel species of fungi described in the present study include the following from Malaysia: Castanediella eucalypti from Eucalyptus pellita, Codinaea acacia from Acacia mangium, Emarcea eucalyptigena… Expand
Fungal Planet description sheets: 107–127
TLDR
Novel species of microfungi described in the present study include the following from Australia and South Africa; Morphological and culture characteristics along with ITS DNA barcodes are provided for all taxa. Expand
Stem cankers on sunflower (Helianthus annuus) in Australia reveal a complex of pathogenic Diaporthe (Phomopsis) species
TLDR
It is shown that there has been broad misapplication of the name D. helianthi to many isolates of Diaporthe (Phomopsis) found causing, or associated with, stem cankers on sunflower. Expand
Endophytic and pathogenic Phyllosticta species, with reference to those associated with Citrus Black Spot
TLDR
DNA sequence analysis of the nrDNA internal transcribed spacer region and partial translation elongation factor 1-alpha (TEF1), actin and glyceraldehyde-3-phosphate dehydrogenase (GPDH) genes resolved nine clades correlating to seven known, and two apparently undescribed species, suggesting that endophytic, non-pathogenic isolate occurring on a wide host range would be more correctly referred to as P. capitalensis. Expand
A phylogenetic and taxonomic re-evaluation of the Bipolaris - Cochliobolus - Curvularia Complex
TLDR
The nomenclatural conflict in this complex is resolved giving priority to the more commonly used established generic names Bipolaris and Curvularia, and species resolved in this study are transferred to one of these genera based on their phylogeny. Expand
Fungal Planet description sheets: 69–91
TLDR
Morphological and culture characteristics along with ITS DNA barcodes are provided for all taxa. Expand
One stop shop: backbones trees for important phytopathogenic genera: I (2014)
TLDR
This study provides phylogenetic synopses for 25 groups of plant pathogenic fungi in the Ascomycota, BasidiomyCota, Mucormycotina (Fungi), and Oomycota using recent molecular data, up-to-date names, and the latest taxonomic insights. Expand
Green and brown bridges between weeds and crops reveal novel Diaporthe species in Australia
TLDR
Eight novel Diaporthe species isolated from live and/or dead tissue from the broad acre crops lupin, maize, mungbean, soybean and sunflower, and associated weed species in Queensland and New South Wales, as well as the environmental weed bitou bush in eastern Australia are described. Expand
