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.
The asci are globose, deliquescent, and scattered throughout the interior cavity i.e. as in Eurotium or arising in tufts from the basal region of ascocarps as in Erysiphe. In this case the ascocarp is round with the hymenium enclosed, so the spores do not automatically get released, and fungi with cleistothecia have had to develop new ...
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.
The clavate asci which contain ascospores are produced by the ascogenous hyphae with the broad base or a short broad stalk. [1] Only a cluster of asci would be formed in a mature apothecium, and as the asci successfully mature, the asci shrink to a short stipe and give rise to a large attached operculum . [ 8 ]
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 ...
Peziza cerea, commonly known as the Cellar Cup is a species of ascomycete fungus in the genus Peziza, family Pezizaceae.In common with other ascomycetes the upper surface of the fungus has a layer of cylindrical spore producing cells called asci, from which the ascospores are forcibly discharged.
Pezizomycetes are a class of fungi within the division Ascomycota.. Pezizomycetes are apothecial fungi, meaning that their spore-producing/releasing bodies are typically disk-like, bearing on their upper surfaces a layer of cylindrical spore-producing cells called asci, from which the spores are forcibly discharged.
