In Romania, Verbascum phlomoides known as mullein is considered to be a plant used in traditional medicine as tea or decoct from flowers and leaves. As tea it is used to ameliorate on short time some pulmonary affections as cough acute and chronic bronchitis, cold, flu, bronchial catarrh, pneumonia, pleurisy, pulmonary congestion, angina, laryngitis, tracheitis, hoarseness and even tuberculosis. As decoct it is mentioned to help as emollient to ameliorate and specially in the history it was mentioned by antiques Greek physicians to cure some affections as there are expectoration, asthma, neurological disorders and some injuries. During the researches carried out on medicinal plants pathogens from the wild flora of the south-western part of Romania it was found on Verbascum phlomoides plants on different populations some leaf spots that was suspected to be produced by a leaf pathogen . Later on laboratory work it was determined that the leaf pathogen that cause the spots on the leafs was Phyllosticta verbasicola. In the present paper there are facts about the disease incidence on the previous mentiond area. First we determine in three parts of the area of interest some significant populations of Verbascum phlomoides concentrated on small areas. All this areas has as common point that they are situated near the Nera stream but on higher ground and on meadow sandy soil. There are a lot of Verbascum phlomoides plants on the Nera Canyon but there are small groups of 1-6 plants there was hard to find places where the river medow was large enough to find more than five of this mullein groups. During the last years we learned that this pathogen was always present on mullein plants with different but since now it doesn’t produce lethal attacks. In the present paper there are data about fungus Phyllosticta verbasicola attack parameters on the reference area
