The Order Mucorales is a group of fungi within the phylum Zygomycota (or more recently classified under Mucoromycota) that are mostly saprophytic, growing on decaying organic matter such as soil, dung, and rotting food. They are characterized by coenocytic (aseptate) hyphae, rapid growth, and the production of sporangiospores in sporangia for asexual reproduction, while sexual reproduction occurs through zygospores. Members of Mucorales, such as Mucor, Rhizopus, and Absidia, are ecologically important as decomposers and are also used in industrial processes like fermentation. Some species, however, can act as opportunistic pathogens, causing infections in immunocompromised humans.
