Colletotrichum (against weeds) Corda 1831
Colletotrichum is a large genus of fungi and includes many important pathogens of crops (see Colletotrichum as crop pathogens). However some strains of plant pathogenic species are also investigated or used as biological control agents of weeds. This page deals with the latter group. In general, the weed pathogens are also known to infect crops, but in some cases they are considered different subspecies, varieties or formae speciales.
The conidia are hyaline, oval to elyptical in shape. These are formed in small fruiting bodies (acervuli) at the surface of the infected plants. The acervuli are often dark and contain black spines (setae). The sexual forms have been described under the genus Glomerella Spauld. & H. Schrenk, 1903.
For a taxonomic review of the genus see Marin-Felix et al. (2017).
