Fuligo septica (L.) F.H.Wigg
Slime mold
This slime mold has some pretty unsavory names, like dog vomit, but it is commonplace in damp weather, on rotting leaves, wood and in bark mulch. It munches on fungal spores, bacteria, and other microbes. Slime mold is pretty amazing stuff. It is a “eukaryotic microbe”—a giant, single-celled organism, one of more than 30,000 species. Identification: The bright yellow, jellylike slime, which seems to appear out of nowhere after wet weather, is conspicuous and hard to confuse. Photo 22 shows it in a hard, crusty phase, with a white powdery top. In photo 11, it is in its dormant, dried out phase. This looks a bit like soil, but it is a fine powder which explodes like a smoke bomb if you step on it. Edibility: Just kidding. I took a time lapse movie of this slime mold, atop some decaying bark mulch. It appeared to be dormant for most of the several hours, but in this segment, covering about 15-20 minutes, it seems to come alive like a creature from the Twilight Zone:
