This group of fungi includes many plant pathogens (see the plant pathogenic Dothideomycetes). However, some forms and strains also have antagonistic properties against other fungi and have been studied as possible biological control agents of plant pathogens. This page deals with the latter group.
The Dothideomycetes is a large class of fungi characterized by the asci already forming in an unfertized mass of hyphae (the stroma) and having a double wall (bitunicate). After absorbing water, the asci expand and push the ascopsores out of the pseudothecia. Today, the Dothideomycetes are more precisely defined by their genetic structure.
The following orders of antagonistic Dothideomycetes are included in the system:
