The Ascomycota comprise about 30,000 described species, including most of the blue-green, red, and brown molds that cause food spoilage, including the salmon coloured bread mold. Ascomycetes are the causes of a number of serious plant diseases, like Dutch elm disease, but the group also includes edible morels and truffles. This group also includes the yeasts used in the production of beer, wine and bread. With the exception of unicellular yeasts, the Ascomycetes are filamentous during development and their hyphae are septate (divided into cells).
Reproduction is usually by the formation of specialized spores, called conidia, borne at the tips of hyphae in specialized structures(conidiopores).
Aquatic fungi in this group are predominantly found on submerged wood, but others are free floating or found on sediments and algae.
