Phycomyces

Phycomyces is a genus of fungus in the phylum Mucoromycota. They are known for their strong phototropism response and helical growth of the sporangium. The best studied species is Phycomyces blakesleeanus.

==Asexual reproduction== Phycomyces can reproduce via extension of mycelia, or by production of spores either asexually or sexually. The asexual cycle includes the formation of spore containing sporangia borne on the top of sporangiophores that may extend 10 to 15 cm above the surface of the fungal colony from which they emerged. The long filamentous sporangiophores respond to divergent environmental signals including light, gravity, wind, chemicals, and adjacent objects. The sporangia contain vegetative spores with one to six haploid nuclei. When these spores are dispersed, they can establish new colonies.
