The good news is that even when a tree or a rose is severely infected with anthracnose, it will not kill it. Based on similarity of morphological features (colony colour, texture presence of septate mycelia or not, spore shape and number of septa), fungal colonies were grouped into 3 species and were identified as Colletotrichum gloeosporioides, Aspergillus niger and Rhizopus oryzae. Anthracnose is one of the most common and serious diseases in horticulture. Twenty-nine isolates from different areas were selected for sequencing and analyses of the internal transcribed spacer region, glyceraldehyde-3-phosphate dehydrogenase, partial actin, β-tubulin, and chitin synthase genomic regions.
