Asci and Ascospores of Morchella sp. in 400X. After sexual fusion of antheridium and ascogonium, the developing dikaryotic hypha with two different strains of nuclei cooperate into a fruiting body called ascocarp. In this picture, asci in the hymenium of ascocarp are shown as the sacs where ascospores (dark structure) are formed inside as a product of meiosis. Usually, there are 8-32 ascospores within a ascus depending on the numbers of rounds of mitosis followed by meiosis. Ascospores are then to germinate into new mycelium after propulsion of these meiospores.
Very detailed and informative description. Absolutely good for revision. Yet pls note that haploid hyphae are also incorporated into the ascocarp.
