Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. … WebOf all, the ascus is the most important and it is this character which makes a fungus an Ascomycete.

Ascomycota

WebMost ascomycete species have eight spores per ascus. Between the asci are the paraphyses (shown here as brown-walled with light grey interiors). Sometimes these are just simple, unmodified hyphae - but often they are modified hyphae. They may have broader apices, perhaps coloured or encrusted. WebJun 17, 1999 · Ascomycetes are the largest group of true fungi, and characteristically produce their sexual spores in a sac-like structure called the ascus.

Mostly they are terrestrial, parasitic or coprophilous. They are unicellular or multicellular fungi. The mycelium is made up of septate and branched hyphae.
