Answer 2

Ascus is a sporangial sac peculiar to Ascomycetes. $4-8$ haploid ascospores are produced internally in each ascus. The asci may occur freely or get aggregated with dikaryotic mycelium to form fructifications called ascocarps. Ascocarps are of many types: cup-like (apothecium, e.g., Peziza), flask shaped (perithecium, e.g., Neurospora), elongated with a slit (hysterothecium) or closed (deistothecium, e.g., Penicillium).
