Mangroves play an important role in coastal ecosystems. In this work, Cladosporium spp were isolated from a natural mangrove environment in Zhanjiang Bay, Guangdong Province, China. Ninety-one isolates were obtained and identified as Cladosporium cladosporioides, C.colocasiae, C.oxysporum, C.perangustum, C.sphaerospermum, C.tenuissimum and C.uredinicola. Forty-two isolates were selected and tested for pathogenicity towards mangroves. The results showed that pathogenic isolates were found on Avicennia marina, Kandelia candel and Rhizophora stylosa with prevalence of 93.40%, 83.52% and 7.41%, respectively. This indicated that A.marina and K.candel were more vulnerable to Cladosporium ssp. than R.stylosa. Among the seven species, C.colocasiae had the strongest pathogenic effect towards A.marina and K.candel with a prevalence of 100.00%. The rest of the seven species also showed pathogenic effects on the same plants. These results provided valuable insights into the effect of various pathogens on mangroves.
