They include the familiar bread mold, Rhizopus stolonifer, Figure B Zygomycete life cycle: Zygomycetes have asexual and sexual.The pairs of nuclei eventually fuse, as well, and the entire multinucleate structure becomes a zygosporangium.

 

They reproduce sexually when adjacent hyphae of the two types release pheromones.

Black Bread Mold Rhizopus stolonifer.

 

After three days you will see that there will be green, white and black spots showing the bread mold growth.

 

The black speckles that Rhizopus produces on bread are capsules, called sporangia, that the fungus produces through asexual reproduction.

 

They may remain dormant until environmental conditions become favorable.

 

The zygosporangium can wait out the worst of environmental conditions for months, and then revive when environment conditions are again favorable.

 

The fungi usually reproduce asexually by producing sporangiospores.
