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 ...
Ascomycota is a phylum of the ... lorchels, and caterpillar fungus. [8] It also contains microscopic fungi ... Spore types can be used as taxonomic characters in the ...
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.
Pisorisporiales is an order of fungi within the phylum of Ascomycota and in the class Sordariomycetes and subdivision of Pezizomycotina and also its own subclass Pisorisporiomycetidae. [ 3 ] [ 4 ] It contains the monotypic family Pisorisporiaceae and 2 genera; Achroceratosphaeria (2 species) and Pisorisporium (2 species).
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 .
The hymenium (spore-bearing surface) is on the outside of the cap. The transparent spores are long and elliptical, measuring 25–30 × 11–14 μm. The surface of the spores is rough to webbed and they contain 1-3 oil drops. [5] Each ascus contains 8 spores, and measures 18-25 x 440-525 μm. The walls of the asci show no reaction in Melzer's ...
The Pezizaceae (commonly referred to as cup fungi) are a family of fungi in the Ascomycota which produce mushrooms that tend to grow in the shape of a "cup". Spores are formed on the inner surface of the fruit body . The cup shape typically serves to focus raindrops into splashing spores out of the cup.
Bipolaris sacchari is a fungal plant pathogen in the family Pleosporaceae.. Bipolaris sacchari is an ascomycete fungal pathogen most notably affecting sugarcane. In its sexual stage, it produces spores housed in an ascus (a sac, usually with 8 spores inside).
