Phycomyces blakesleeanus

Phycomyces blakesleeanus is a filamentous fungus in the Order Mucorales of the phylum Zygomycota or subphylum Mucoromycotina.

The spore-bearing sporangiophores of Phycomyces are very sensitive to different environmental signals including light, gravity, wind, chemicals, and adjacent objects.

This response is believed to result from an unidentified "avoidance gas" that is emitted by the growing zone of the sporangiophore.

Zygospores are the sexual structures of P. blakesleeanus in which the diploid zygote is formed and meiosis is presumed to take place.
