Some zygomycetes, however, can actually aim their spores. For example, Pilobolus , a fungus that decomposes animal dung, bends sporangium-bearing hyphae toward light, where grass is likely to be growing. The sporangium is shot out of the hypha, dispersing spores away from the dung and onto surrounding grass. If an herbivore eats the grass and consumes the spores, the asexual life cycle is completed when the animal disperses the spores in its feces. Ascomycetes include unicellular yeasts and complex multicellular cup fungi.
Hyphae are septate.
In asexual reproduction, the tips of specialized hyphae form conidia , which are chains of haploid, asexual spores that are usually wind dispersed. In sexual reproduction, haploid mycelia of opposite mating strains fuse.
