The studies were carried out on common reed (Phragmites australis) growing on the shores of Lake Glinno and forming rush communities of the alliance Phragmition. 10 plants with disease symptoms were gathered from each of five sites. The isolation and marking of pathogens were performed twice from fragments of leaf and blade tissues with disease symptoms. First, directly after collecting the plants incubated in sterile humid chambers and microorganism cultures on CDA and PDA medium, and then phytopathogen and saprotroph species occurring on dried green material were identified for 2-4 months. The occurrence of 31 species of microscopic fungi overall was observed on the leaves, blades and inflorescences of P. australis, including 2 mycelia of Mycelia sterilia. The most frequently occurring species, present at all sites of Phragmites australis are: Alternaria alternata, Cladosporium cladosporioides, C. herbarum, Doratomyces stemonitis and Puccinia phragmitis, P. magnussiana and two mycelia of Mycelia sterilia. The most common species occurring on blades and inside them are: Acremoniella atra, Acremonium alternatum and Fusarium sambucinum. Sporadically, Ustilago grandis was also observed inside blades. Tiny necrotic stains on leaves and blades were caused by the presence of three species of the genus Leptoshaeria: L. culmifraga, L. eustoma and L. fuckelli. The occurrence of the sclerote of Claviceps microcephala was found in inflorescences
