| Abstract: | Sooty blotch and flyspeck is a fungal disease complex that colonizes a wide range of plants. In a survey of host plants for sooty blotch and flyspeck fungi, we obtained an isolate associated with discrete flyspeck symptom on stems of the Rubber Trees, Ficus elastica, from Haikou, Hainan, China. A pure culture was obtained, and the nuclear ITS region of rDNA was amplified by PCR. Molecular phylogeny inferred from ITS sequence data suggested that it was close to Devriesia strelitziae, reported from South Africa. Morphologically, it was characterized by longer conidia, more conidial septa, and having chlamydospores. Therefore, we describe our isolate as a novel species of Devriesia. |
