Type of Ascocarp: (i) Cleistothecium : It is found in penicillium and Aspergillus. It is a rounded and closed body. The ascospores come out by the decay bf clistothecium wall. (ii) Percithecium : It is found in Claviceps and Neurospora fungus. This types of ascocarp is a flask shaped body having an apical opening, called ostiole. The cavity of perthecium contain ascospores which come out through the ostiole aperture. (iii) Apothecium : It is found in Marchella and Morels. It is a cup shaped fruiting body.
