Cheirosporium gen. nov. is characterised by the production of sporodochial conidiomata, semi-macronematous to macronematous conidiophores that possess several distinct sterile branches, and cheiroid, smooth-walled conidia with rhexolytic secession. The 28S rDNA and ITS rDNA operon of this taxon were amplified and sequenced. A BLAST search revealed low homology between Cheirosporium triseriale a...

Harknessiaceae is introduced as a new family in the ascomycete order Diaporthales to accommodate species of Harknessia with their Wuestneia-like teleomorphs. The family is distinguished by having pycnidial conidiomata with brown, furfuraceous margins, brown conidia with hyaline, tube-like basal appendages, longitudinal striations, and rhexolytic secession. Six species occurring on Eucalyptus ar...

Shot hole disease of stone fruit trees, caused by Wilsonomyces carpophilus (Lév.) Adaskaveg, Ogawa & Butler(= Stigmina carpophila (Lév.) M.B. Ellis and Coryneum beijerinckii Oud.) is a serious disease of Prunus species in West Azerbaijan province. The pathogen was obtained from infected leaves, fruits and twigs of Prunus orchards during spring and summer of 2007. Samples were cultured on PDA, M...

Canalisporium variabile sp. nov. is described and illustrated based on several specimens from submerged wood and decaying palm rachis in Australia. It is most similar to C. pallidurn in having pale conidia with clearly visible septa and canals, but they are two distinct species. In C. pallidurn, conidia are more stable in shape, size and septation, with mostly a single column of vertical septa....
