Pyrenophora consists of endophytes, pathogens and saprobes that are widely distributed on various cereal crops and grass hosts. Pyrenophora trichostoma was found on Bromopsis inermis in Russia (Rostov region) and it is described as the first record of this species from this host. The fungus, a sexual morph, was isolated using the single spore isolation technique. The morphology is illustrated and a description has been provided. Sequence data of the LSU and ITS gene regions were analysed to confirm the phylogenetic placement of the species. The history of P. trichostoma, its distribution and economic impact as a pathogen that causes leaf spots on cereals and wheat, has been discussed.
