â¢During asexual reproduction, haploid spores are. produced in structures called sporangia that form at the tips of specialized hyphae. â¢The haploid spores are produced by mitosis. â¢Spores are carried by wind to new locations, where they grow into new fungi.ac Fungi Key Idea: Sac fungi are characterized by an ascus, a saclike sexual reproductive structure that produces spores. â¢An ascus is a âsac.â.
