Spores within an ascus (sack).

The meiospore produced in the ascus of an ascomycete.

a general classification for spores produced by sexual reproduction and can include Aspergillus and Peni- cillium. Often identified from fungi growing in damp areas

these are the spores of sexual origin, produced inside the ascus.

Sexual spores produced by Ascomycetes.

Spores produced in a saclike structure (the ascus). This structure is typical of a large group of fungi, the Ascomycetes.

(ass-co'-spores) - A large category of spores (produced in a sac-like structure) that are found everywhere in nature and include more than 3000 genera. Most Ascospores of health or IAQ importance are identified separately by their genus (e.g. Chaetomium) when possible on a IAQ report, and the Ascospore category is used primarily on these reports for a large group of less important spore types often found in quantity on outdoor air samples. On tape samples, Ascospore is sometimes also used as a general morphological identification (i.e. the ascus or sac structure is present) for certain samples in those cases when the spores do not appear to represent any of the IAQ significant genera.
