Colletotrichum can be identified as the major causative fungal agent of avocado anthracnose all over the world. In Sri Lanka, Colletotrichum gloeosporioides reported to be the sole causative agent of avocado anthracnose. This paper presents a morphological, genetic and pathogenic study conducted using Colletotrichum isolates collected from different avocado cultivating areas of Sri Lanka. Here, the identity of C. gloeosporioides has been confirmed using multi locus phylogeny as the major
