▪ fruiting structure of fungi
also called  ascoma,  plural  ascomata 

      fruiting structure of fungi of the phylum Ascomycota (kingdom Fungi). It arises from vegetative filaments (hyphae) after sexual reproduction has been initiated. The ascocarp (in forms called apothecium, cleistothecium [cleistocarp], or perithecium) contain saclike structures (asci) that usually bear four to eight ascospores. Apothecia are stalked and either disklike, saucer-shaped, or cup-shaped with exposed asci. The largest known apothecium, produced by Geopyxis cacabus, has a stalk 1 metre (40 inches) high and a cup 50 centimetres (20 inches) across. Cleistothecia are spherical and must rupture or disintegrate to release their ascospores. Perithecia are globular or flask-shaped with an apical opening for discharge of ascospores.
