Abstract: Colletotrichum species are the causal agents of potato and tomato diseases, such as black dot and anthracnose. Several new species and species complexes were recently established. Thereby, a reassessment of the genus diversity is required. The study revealed two species, Colletotrichum coccodes and Colletotrichum nigrum , as Russia’s main disease agents of cultivated Solanaceae plants. Black dot and anthracnose in potato were caused exclusively by C. coccodes , whereas the same diseases in tomato, eggplant, and pepper were predominately caused by C. nigrum . However, one isolate of C. coccodes was also identified as an agent of the tomato disease. Five potentially hybrid isolates were discovered. Morphological examination and pathogenicity assessment revealed no significant differences between the two Colletotrichum species. All isolates were sensitive to the fungicides azoxystrobin, difenoconazole, and thiabendazole, which are currently used in agriculture. This is the first report of the occurrence of C. nigrum in Russia.
