(D) In $Agaricus$ (a member of Basidiomycetes),the sexual spores are called basidiospores.These spores are produced exogenously on club-shaped structures called basidia.Following karyogamy and meiosis within the basidium,the resulting nuclei migrate into outgrowths called sterigmata to form basidiospores externally.In contrast,$Saccharomyces$ and $Neurospora$ are Ascomycetes,where spores (ascospores) are produced endogenously within an ascus.$Alternaria$ belongs to Deuteromycetes and does not produce sexual spores.
