Zygospore

A zygospore is a reproductive part of a fungus, a chlamydospore that is created by the nuclear fusion of haploid hyphae of different mating types.

A zygospore remains dormant while it waits for environmental cues, such as moisture, heat, or chemicals secreted by plants.

When the environment is favorable, the zygospore germinates, meiosis occurs, and a sporangium is produced at the end of a sporangiophore. The sporangium sheds spores.

A fungus that forms zygospores is called a zygomycete, indicating that the class (biology) is characterized by this evolutionary development.
