  2. SordariafimicolaLife cycle Sordariafimicola is an ascomycete fungus that can be used to demonstrate the results of crossing over during meiosis. Sordaria is a haploid organism for most of its life cycle. It becomes diploid only when the fusion of the mycelia (filametlike groups of cells) of two different strains results in the fusion of the two different types of haploid nuclei to form a diploid nucleus. The diploid nucleus must then undergo meiosis to resume its haploid state. Meiosis followed by mitosis, in Sordaria results in the formation of eight haploid ascospores contained within a sac called an ascus (plural, asci). Many asci are contained within a fruiting body called a perithecium. When the ascospores are mature, the ascus ruptures, releasing the spores. Each spore can develop into a new haploid fungus.
