What are the sexual spores of Ascomycetes called?

Step-by-step solution

Commonly known as sac-fungi, the ascomycetes are mostly multicellular, e.g., Penicillium, or rarelyunicellular, e.g., yeast (Saccharomyces). They are saprophytic, decomposers, parasitic or coprophilous (growing on dung). Mycelium is branched and septate. The asexual spores are conidia produced exogenously on the special mycelium called conidiophores. Conidia on germination produce mycelium. Sexual spores are called ascospores which are produced endogenously in sac like asci (singular ascus). These asci are arranged
