Resumen

The genus Helichrysumis a valuable source of essential oils with medicinal properties. Eighty endophytic fungi have been isolated from 8 Helichrysum stoechasplants belonging to two different biotypes of Catalonia. Based on their morphology, 10 different genera have been identified while otherhave been assigned to 21 OTUs. The colonization rate was similar in bothlocations (71.53% and 67.36%) and in the entire plants (60-75%).In plant organs values ranged between 50 and 91.67.The PDA wasthe nutrient medium which provided the highest number of different colonies considering allthree media used (PDA, MEA and LCA). The colonization frequency index showeda tendency of the genera and OTUs to specificity of a single organ (21 OTUs and genera were obtained from a single organ, 8 from two organs and only 1 from all the organs used), and nutrientmedium (18 OTUs and genera were isolated in a single nutrient medium, 9 in two nutrientmedia and only 3 in all media used). The most frequent genera / OTUs were Alternariaand OTU1.
