The sporangiophore is bending toward light entering the picture from the left. This example of how a fungal cell responds to the environment was one of the very first to be studied by genetic methods, pioneered by Nobel laureate Max Delbruck. Image: Corrochano et al.

Phycomyces belongs to a basal fungal lineage, considered simpler and ancestral, yet the large (to a microbiologist) spore-bearing structures, called sporangiophores, respond to light, gravity, wind, and even the proximity of an object.
