The aim of this study was to collect the isolates of Colletotrichum spp. in Serbia and to study its pathogenicity and morphological characteristics. A detailed study of alfalfa anthracnose inducer enables us to understand pathologic processes and possibilities for eradication of this pathogen agent. During these studies, it was determined that all of the isolates were causing the symptoms of alfalfa anthracnose. All of the selected isolates form germinative bodies - acervulae - on mycelium. Acervulae can be grouped or scattered across the colony area. Their size in the culture was 100 - 250 mm. Conidia were short, cylindrical, relatively broad, with both end obtuse 7.85 x 3.85 mm. Appressoria were ovate to obovoid, pale to medium brown 7.5-16.5 x 5.5-8.9 microm.
