Dog Vomit Slime Mold (Scrambled Egg Slime Mold)
Yellow, tan, or whitish fluffy or foamy-looking mass, becoming dried, crusty, and dark, eventually releasing many, many spores. Late spring through fall; common when it is hot and humid. Plasmodium (growth) stage a plate-sized, irregular mass that "creeps" gradually over wood mulch or other substrate; yellow, tan, or whitish; texture fluffy or foamy, slimy, soft, sometimes bleeding dark fluid. Sporangium (spore-producing) stage dries and hardens; becoming dark tan, brown, or black; eventually becoming a mass of dark, dusty spores. Spores pinkish-brown. Spores magnified are round, slightly spiny.
Lookalikes: There are many other species of slime molds, but this is one of the most common and noticed, as it looks amazingly like a foamy or spongy patch of dog vomit or scrambled eggs.
