Aegagropiles are conglomerations of fibre debris from Posidonia oceanica meadows that frequently found along Mediterranean beaches, but the plant organ which these fibres arise remains unknown. In this study, a histological comparison P. organs 3 shoots with structure aegagropile showed most them leaf sheaths and rhizomes, suggesting they degradation products “matte” rather than litter, is main...

There are five closely related Sporobolus species, collectively known as weedy grasses (WSG) or the rat’s tail grasses. They fast growing, highly competitive, unpalatable weeds of pastures, roadsides and woodlands. An effective biological control agent would be a welcomed alternative to successive herbicide application manual removal methods. This study describes initial exploratory phase isola...

Sequence data from the 18S nrDNA (SSU) and 28S nrDNA (LSU) regions of isolates of Phoma section Paraphoma were compared with those of representative isolates of the morphologically similar anamorph genera Pleurophoma and Pyrenochaeta and of the type species of Phoma sections Phoma, Pilosa and Plenodomus. Phoma section Paraphoma was found to be highly polyphyletic within the Pleosporales and onl...

False smut caused by Cercospora seminalis is an important disease of buffalograss (Buchloë dactyloides) affecting seed production. The pathogen prevents normal caryopsis development and causes considerable yield loss and reduced seed germination. The current taxonomic placement of the false-smut causal pathogen in the genus Cercospora is incorrect based on its morphological characteristics and ...
