Mucor L. (1953), also called as black mould or pin-mould, belongs to the subdivision Zygomycotina, class Zygomycetes, order Mucorales and family Mucoraceae. Mucoralean species have a well-developed mycelium that is generally aseptate. Mucorales can also be separated from other orders of Zygomycetes by their relatively non-specialized associations with other organisms, besides a combination of their asexual and sexual reproductive structures. The mucoralean genera produce non-apophysate sporangia, with either deliquescent or persistent walls. There is often a slight constriction on the sporangiophore immediately below the sporangium. Mucor is a large genus and occurs throughout the world. Most of the species are saprobes, while some are weak parasites. The genus in general is heterothallic.
