Fungi belonging to Phoma spp. commonly occur on herbaceous plants, including herbal ones. In the years 2004–2006 isolates belonging to genus Phoma which were differentiated in morphological respects were obtained from herbs belonging to family Lamiaceae. Basing on constant morphological feature observed in vitro in the cultures developing on standard media, isolates of Phoma spp. were included within the proper section, and next the species were identified. P. exiqua var. exiqua was isolated from all parts of the examined plants. P. nepeticola cultures were obtained from the leaves and stems of motherwort, whereas isolates of P. nemophilae were from the roots. Apart from the above mentioned species, P. capitulum, P. labilis, P. pereupyrena, P. subglomerata and P. septicidalis were also isolated.
