Phyllosticta capitalensis is an endophyte and weak plant pathogen with a worldwide distribution presently known from 70 plant families. This study isolated P. capitalensis from different host plants in northern Thailand, and determined their different life modes. Thirty strains of P. capitalensis were isolated as endophytes from 20 hosts. An additional 30 strains of P. capitalensis from other hosts and geographic locations were also obtained from established culture collections. Phylogenetic analysis using ITS, ACT and TEF gene data confirmed the identity of all isolates. Pathogenicity tests with five strains of P. capitalensis originating from different hosts were completed on their respective host plants. In all cases there was no infection of healthy leaves, indicating that this endophyte does not cause disease on healthy, unstressed host plants. That P. capitalensis is often isolated as an endophyte has important implications in fungal biology and plant health. Due to its endophytic nature, P. capitalensis is commonly found associated with lesions of plants, and often incorrectly identified as a species of quarantine importance, which again has implications for trade in agricultural and forestry production.
