This 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.
For a taxonomic review of this class see Wijayawardene et al., 2014.
