Phycomyces blakesleeanus is a fungus in the same family as Rhizopus. It produces very long stalks atop which sit the small round spore packets. We tried to use this characteristic to produce a head of “hair” on Homer. The trick was covering Homer’s head with enough growth medium but not let it run onto areas we didn’t want the fungus to grow. In addition to Phycomyces, other fungi eventually grew to help give Homer some semblance of hair. This movie was made over a 5 day, 12 hour period with images taken at 10 minute intervals.
