asci are cylindrical; spores spindle-shaped, straight or bow-shaped, rough, 35–8; paraphyses thread-shaped.
The asci are cylindrical, slightly pointed at the apex, 8-spored.
These cysts are respectively known as sporangia, and asci or thecæ.
The asci differ in shape and size, according to the species.
Two asci of same, and contained spores, and accompanying filaments; more magnified.
In the genus Elaphomyces, the asci are more than commonly diffluent.
In some of these, the asci are evanescent, but in the greater number are permanent.
Saccardo calls its asci (sacs which contain the spores) sporangia.
Ascus (asci), a sac, the spore-case of Lichens and some Fungi.
The asci are always present, the paraphyses are sometimes rare, and the mucilage in many cases seems to be entirely wanting.
"sac in certain fungi," 1830, Modern Latin, from Greek askos "leather bag, wine skin," of unknown origin.
ascus as·cus (ās'kəs)
n. pl. as·ci (ās'ī', -kī')
A membranous, often club-shaped structure in which typically eight spores are formed through sexual reproduction of ascomycetes.
Plural asci (ās'ī', -kī')
A membranous, often club-shaped structure inside which ascospores are formed through sexual reproduction in species of the fungi known as ascomycetes. The ascus is unique to ascomycetes and distinguishes them from other kinds of fungi. Asci are formed when two hyphae that are sexually compatible conjugate. Each ascus typically develops eight ascospores. Asci swell at maturity until they burst, shooting the ascospores into the air.
