The fungi Saccharomyces produces ascospores when grown on V-8 medium, acetate ascospore agar, or Gorodkowa medium. These ascospores are globose and located in asci. Each ascus contains one to four ascospores. The asci do not rupture at maturity. Ascospores are stained with Kinyoun stain and ascospore stain.
An ascocarp, or ascoma (pl.: ascomata), is the fruiting body of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores.
As an ascomycete, Ceratocystis coerulescens produces ascospores encased as groups of eight in asci. The asci are protected by a perithecium, a flask-shaped ascocarp, in which the pathogen overwinters. Ascospores are the sexual spores and are far less common than the asexual spores known as conidia.
The defining feature of this fungal group is the "ascus" (from Ancient Greek ἀσκός (askós) 'sac, wineskin'), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of Ascomycota are asexual and thus do not form asci or ascospores.
P. capsellae is an ascomycete, meaning it produces ascospores housed in asci as means of sexual reproduction. Sexual structures are found in the sexual stage of this fungus, which has been classified as Mycosphaerella capsellae. The ascocarp of M. capsellae is a cleistothecium, meaning asci are shielded from the environment prior to ascospore ...
Randomly arranged ascospores that set in the upper area of asci would be discharged through operculum at the asci tip. [9] The ultrastructure of ascospores of A. nigricans was investigated to have a deeper understanding of the formation of wall layers and ornamentation of ascospores. The invagination of the plasma membrane of ascus generates ...

The bitunicate asci are thick-walled, with an outer and inner layer. The outer and inner layer of the ascus wall are called exotunica and endotunica, and they separate during ascospore release. [6] The asci usually contains eight ascospores, while the shape and separation of the ascospores are more variating. [13]
