The Ascomycota are the largest group of fungi, with over 32,000 species. They can be identified by their possession of the ascus, a pod-like container of spores and can also reproduce asexually by segmentation of the hyphae to form conidiospores. Most are mycorrhizal and almost half of the known species form lichens. They range from single cell yeasts through moulds, like Penicillium, to the morels and truffles with their large fruiting bodies.
