Abstract: Among the Colletotrichum strains isolated from Anthurium andraeanum in Guangzhou, Nanjing, Yangzhou, there were two groups exhibited different morphology on the culture. Two strains of each group were chose for species identification with the morphological character, pathogencity on plants, host range and the sequence of ribosomal DNA-ITS. The results indicated that these strains belong to two species, Colletotrichum gloeosporioides and C. destructivum, and the latter was first reported as a pathogen in Anthurium andraeanum. Both species could infect solely, crossly and latently.

Key words: Anthurium andraeanum, Colletotrichum, pathogen identification, ribosomal DNA-ITS
