I believe this is of the species commonly known as "Dog Vomit", Fuligo septica .
I got down on my hands and knees to take dozens of photos. With those as a source, I cobbled together a scene and drawing plan for this wonderful maze.
This maze took just under two months to draw. I used several variants of a spiral to draw the ends of the pendulous fruiting bodies. The zigzagging paths define the shape of the cones as well as the pulsing exploratory channels that the slime mold uses to explore its environment.
Interestingly, during the time that was drawing this, slime molds came into the news in Wired Magazine . It seems that slime molds' growth pattern makes it adept at solving mazes. Well, I've turned that on its non-existent head: sometimes the slime mold solves mazes, sometimes the slime mold is the maze.
