Asexual reproduction with conidia: Ascomycetes typically reproduce asexually by producing conidia (asexual spores) exogenously on specialized hyphae called conidiophores.

Produce fruiting bodies: They form sexual fruiting bodies called ascocarps.

Sexual spores produced endogenously: Their sexual spores, called ascospores, are produced internally (endogenously) within a sac-like structure.

Karyogamy and meiosis in an ascus: The fusion of nuclei (karyogamy) and subsequent reduction division (meiosis) occur inside the ascus (plural: asci), which is the defining characteristic of this group.
