Ascomycota (weed pathogens)

The Ascomycota are a large group of fungi, including many plant pathogens. The sexual fruiting bodies (ascocarps) have various shapes but all contain sac-like structure (the asci) which produce ascospores. The group also includes several genera and species which reproduce asexually only. Further, some single-celled groups do not form fruiting bodies, instead the cells develop into asci during sexual reproduction.

Please note that this page only deals with weed pathogens, for other groups of Ascomycota see:

This group includes orders from the classes Dothideomycetes, Leotiomycetes and Sordariomycetes. The following orders of weed pathogenic fungi have been entered into the system:
