The sexual spore produced from meiosis by ascomycetes; they are symmetrical and lack any attachment pegs.
A spore produced within an ascus or spore sac.
A type of reproductive cell known as a sexual spore, produced inside a specialized sac called an ascus, typically found in ascomycetous fungi. This spore formation is a key part of the reproductive cycle in these fungi, allowing for the spread and continuation of their species. The ascus serves as a protective environment where the spores develop before being released into the environment, a process crucial for the propagation and diversity of ascomycetous fungi.
