To obtain extracellular slime we allowed a culture of slime mold to migrate (8–12 h) across a 1% agar surface, leaving behind it a trail of extracellular slime the culture used to generate the extracellular slime was the same laboratory stock as the plasmodium to be tested. We therefore expected the slime mold’s ability to navigate in complex environments to be diminished in particular, we expected plasmodia to take longer to reach the goal on the substrate of extracellular slime, and to spend longer within the bounds of the u-shaped trap, compared with plasmodia on blank agar.
