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. (wikipedia.org)
However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. (wikipedia.org)
The crustose lichen genus Mycoblastus in the Northern Hemisphere includes eight recognized species sharing large, simple ascospores produced 1-2 per ascus in strongly pigmented biatorine apothecia. (cambridge.org)
Each plate consists of close-up macrophotos of the fruiting bodies, often including a cross-section plus asci and ascospores and conidia. (msafungi.org)
The perithecia have a layer of asci (shown below), which contain ascospores. (wisc.edu)
It's a little difficult to conceive how these ascospores get out of the ascus and through the small hole (ostiole) in the top of the perithecium. (wisc.edu)
The asci individually elongate (grow) into the ostiole, and individually forcibly discharge their enclosed ascospores to the outside world. (wisc.edu)

Ascomycetes are fungi that reproduce sexually via the formation of endogenous ascospores (i.e. sexual spores) normally enclosed in a sac known as the ascus sac. (microbiologyclass.net)
The asci (singular: ascus) are known to contain about four or eight ascospores. (microbiologyclass.net)
Their sexual spores (ascospores) develop within tubular sacs called asci that act as small water cannons and expel the spores into the air. (raiseupwa.com)
In most species in this division, fruiting bodies are produced that bear ascospores, in asci (Figures 6a & b). (raiseupwa.com)
The ascospores have mucilaginous covering (Sordaria) or appendages (Podospora) which are attached to the cap of the ascus and helps them to attach to herbage upon dispersal. (raiseupwa.com)
Lanspora dorisauae is characterized by dark-coloured ascomata with a short neck, periphysate ostioles, subclavate, deliquescing asci without an apical ring, presence of wide paraphyses, striated wall ascospores with crown-like appendages on one pole of the ascospores. (bvsalud.org)
ascospores often biseriate, elliptical to inequilateral, 10 - 19 x 3-5 ym, at first non-septate with 2 oil drops, becoming usually 1-septate, occasionally 3-septate, sometimes germinating within the ascus, paraphyses slender, often abruptly swollen to 4 ym thick at the tip. (mycopedia.ch)
Ascocoryne cylichnium (Tulasne) Korf in Phytologia 21: 202 (1971) is very similar but often has larger apothecia and is distinguished by its long ascospores 18-30 x 4-6 ym, which become multiseptate and bud off spherical secondary spores while still in the ascus. (mycopedia.ch)
ascospores 8/ascus, polaribilocular, oblong to broadly ellipsoid, (8.3-)9.7-12.0(-12.8) × (3.7-)5.0-7.1(-8.2) μm, with a moderately thickened, (1.7-)2.8-4.6(-5.9) μm wide septum (n = 40). (lichenportal.org)
ascospores 8 per ascus, (1-) 3-septate to submuriform, often of irregular size and shape, dark greenish brown, 10-24 × 6-10 µm. (biodiversity.no)

Tuber belongs to the phylum Ascomycota, which means that their spores are produced in sacs called asci. (midwestmycology.org)

Ascomycetes produce sexual spores, called axcospores, formed in sac-like structures called asci, and also small asexual spores called conidia. (raiseupwa.com)
All members of Class Ascomycota that reproduce sexually produce an ascus (from the Greek "askos," meaning sac), containing spores. (raiseupwa.com)
Additionally, they feature clavate asci with 4-8 spores. (fungalpedia.org)
The key to identifying to species level the various species of Cheilymenia and Scutellinia (the other main group of eyelash-fringed disc fungi) of which there are close on 50 known in Britain and Ireland, is by microscopic examination of asci, spores and any hairs or 'lashes' that cover the infertile surface. (first-nature.com)
150-220 x 10-15µm, with eight spores per ascus. (first-nature.com)
Few can be identified from macroscopic features alone, and so microscopic examination of asci, spores and other cell structures is usually necessary. (first-nature.com)
