Most of the species undergo asexual reproduction by the formation of multinucleated conidia. In ascomycetes, asexual reproduction is by the formation of conidia exogenously on conidiophores and Sexual reproduction is by conjugation between two gametangia.

Ascospores are oval and enclosed inside of an ascus, which is elongated and cylindrical. Some are economically important and are even consumed. Each conidium germinates, forming a new vegetative mycelium [1]. The mycelium of the ascomycetes is made up of septate or branched hyphae and the cell wall is made up of chitin or -glucans. Some mycologists think that the Basidiomycetes with septate basidia (phragmobasidia) are nearer to the ancestral Ascomycetes. Mycosphaerella, for example, has asci in its stroma. Ascomycota is a phylum of fungi that includes the majority of fungal species on the planet. Many species are Basidiospores are homologous to the ascospores.

The best answers are voted up and rise to the top. WebIntroduction and Importance: Though cosmopolitan in distribution, species of Penicillium are more prevalent in temperate countries. Since the mycelium is hidden within the substratum or soil, in nature, Peziza is visible only when their fruit bodies (mushrooms) are formed on the substrate surface. The germ tube becomes septate, branched and forms a mycelium. One of the daughter nuclei passes into the tube (Fig. 13 B). Many food industries depend on yeast for fermentation like brewing, bread and cheese making. In homothallic, the mycelium is derived from a single ascospore, which is capable of reproducing sexually. The terminal bi-nucleate cell of the ascogenous hyphae elongate (Fig. Outer wall layer is thick spiny, pigmented and known as epispore, whereas the inner one is thin, delicate and is called endospore. A scientist who studies fungi is called Mycologist. will cause significant labor-market disruption over next 5 years, says World Economic Forum. There are no distinct fruiting bodies.
