Studies on the diversity of fungi colonizing and damaging various parts of herbs from Lamiaceae family were carried out in 2004-2009 and from Plantaginaceae family in 2009-2011 correspondingly. Phoma strasseri, the most dangerous pathogen of peppermint (Mentha piperita) was commonly obtained from peppermint rhizomes and stems with symptoms of necrosis and tissue disintegration. Phomopsis sclarea was isolated from sage (Salvia officinalis) stems, showing symptoms of necrosis, peeling off and bark breaking. Phoma nepeticola was obtained from the motherwort (Leonurus cardiaca) leaves and stems with symptoms of small necrotic spots. Phyllosticta plantaginis was isolated from leaves of ribwort (Plantago lanceolata) showing symptoms of small, regular, necrotic spots.
