Rhynchosporium is a genus of fungi that is pathogenic to grass. includes currently four accepted species: R. secalis from barley, R. orthosporum from Dactylis glomerata, R. agropyri from Agropyron, and R. commune from Hordeum spp. and Bromus diandrus.[1] Rhynchosporium secalis is one of the most destructive pathogens of barley worldwide, causing yield decreases of up to 40% and reduced grain quality [2]. It is principally splash dispersed conidia which lead to disease transmission, though other sources (e.g. seed) are known to play a role.
