Slime mold

The mission has ended, but you might find some helpful identifications by looking at the spottings under it: http://www.projectnoah.org/missions/8322190

There are many, many types of slime mold (as you no doubt found out by looking at the mission here). Often they cannot be completely identified without a microscope (true with many fungi). They are amazing creatures--love how they move!--but often hard to spot. Congrats on this spotting.

Could it be some type of slime mold?
