The onset of some sclerotic formations are reported on barley straws on which the following microscopic investigations and biometrical measurements peritecia, ascia and ascospores of <em>Pyrenophora graminea</em> (Rabh. Ito et Kurib.) were detected, representing the sexed multiplication of fungus <em>Helminthosporium gramineum</em>, the pathogenic factor causing leaf tearing in barley, a condition rarely encountered in nature. Owing to the great number of peritecia on barley straw residues, we are of the opinion that the sexed multiplication of fungus represents a real danger in barley cultivation assigning the efficient control steps against this pest.
