Once mature the elastic ring briefly expands and lets the spores shoot out. This type appears both in apothecia and in perithecia; an example is the illustrated Hypomyces chrysospermus. Ascus of Saccharomyces cerevisiae containing a tetrad of four spores. A bitunicate ascus is enclosed in a double wall. This consists of a thin, brittle outer ...

Here the fertile layer is free, so that many spores can be dispersed simultaneously. The morel, Morchella, an edible ascocarp, not a mushroom, favored by gourmets, is a mass of apothecia fused together in a single large structure or cap. The genera Helvella and Gyromitra are similar.
Gelasinospora as a genus is made up of perithecial fungi, meaning that they discharge their ascospores through an ostiole. Spores do not germinate easily, needing a treatment of temperature, chemicals or a combination of the two to initiate germination. Like most ascomycetes, Gelasinospora species typically have 8 spores in each ascus.
Ascomycota life cycle and morphology The phylum Ascomycota , or sac fungus , is characterized by formation of meiotic spores called ascospores enclosed in a special sac called an ascus . The genetic components for sexual reproduction appear to be produced by all members of this group.
The spores range from white to cream to slightly yellow in deposit, although a spore print may be difficult to obtain given the shape of the fruit body. [4] The spores are formed in asci lining the pits—the ridges are sterile. [5] They are ellipsoidal, smooth, thin-walled, translucent , and measure 17.5–21.9 by 8.8–11.0 μm.
The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, [1] while the rest of the life cycle is characterized by vegetative mycelial growth and asexual ...
Saccharomycotina is a subdivision (subphylum) of the division (phylum) Ascomycota in the kingdom Fungi. [2] [3] It comprises most of the ascomycete yeasts.The members of Saccharomycotina reproduce by budding and they do not produce ascocarps (fruiting bodies).
