The sexual reproduction of the Mucoraceae is accomplished by zygospores, resulting from conjugation, and hence they are sometime...s characterised as Zygomycetes. In many of the species this form of reproduction has never been traced, but has been accepted from analogy. Two lateral branches resembling each other, and termed archicarps, are concerned in the process. They resemble at first ordinary branches, which approach each other until the tips meet, but as they increase in size they become clavate, and are densely filled with protoplasm.
