Identification

Plasmodial slime molds are single-celled organisms, masses of protoplasm without cell walls (naked) and with thousands of nuclei. Like animals, they move and violently eject unwanted inorganic materials. Like amoeba, they feed by engulfing particles of food. Like fungi, they reproduce by producing fruit bodies containing spores that are distributed by wind. Formerly classified as fungi, plasmodial slime molds are now known to be unrelated.

Dog vomit slime mold is a plasmodial slime mold. It has a worldwide distribution, occurring on every continent except Greenland and Antarctica. It is often found in urban areas from May to October. It grows on the rotten wood of stumps, logs, and wood mulches; on garden soil enriched with manure; and also on living plants. It may migrate one meter or more to nearby food sources. It feeds on bacteria, spores of fungi and non-flowering plants, protozoa, and nonliving organic matter. Its common name accurately describes its appearance. It is not edible.

Dog vomit slime mold may appear as an irregular cushion-like mass, a slimy sheet, or a crust-like sheet. When it first appears it is a white to yellow slimy sheet 1 to 8 (2.5 to 20 cm) long. At this stage it cannot reliably be distinguished in the field from other similar-looking slime molds. At some point the protoplasm transforms into a large, cushion-like, fruiting body (aethalium). At this stage the slime mold is easily identified in the field. The aethalium is to 1¼ (1 to 3 cm) thick and may be white, yellowish, brownish-yellow, or reddish-brown. It is covered by a brittle crust. Breaking the crust away reveals a dull black spore mass.

Slime Mold, AKA Dog Vomit or Yellow Slime, can pop up in your mulch during the hot and humid months. This fungus is very common and very normal, as it grows in organic material and thrives in hot and moist environments. While unsightly, slime mold is not dangerous to humans or animals.

To learn more about slime mold, when and how to properly remove it, watch this video!

Dog vomit slime mold is an amoeba, a classification of protist (single-celled eukaryotic organism that is neither plant, animal, bacteria, nor fungus) that are amorphous in shape. They move via forming 'feet-like' pseudopodia, which are also used for feeding.

This video shows it's life cycle and common questions are answered along the way and at the end. Enjoy!
