Why ‘Dog Vomit Slime’ Is Spreading Across New York This Summer

A strange, bright yellow growth - commonly nicknamed “dog vomit slime” - has been appearing in yards and gardens throughout New York State this summer.

The substance is actually Fuligo septica, a type of slime mold that often forms as a yellow, gelatinous mass.

In some cases, it can take on orange or brown tones, or develop a crusty, powder-like texture once it dries out.

Experts attribute the surge in sightings this summer to the season’s weather pattern.

Hot and humid weather creates ideal conditions for the mold to grow.

This year’s persistent heat and moisture have made the environment especially favorable.

Typically found on mulch and grassy areas, the mold may look alarming but poses no risk. It doesn't hurt people, pets or plants and can actually turn organic matter into soil.

If it shows up in your yard, you have options.

You can leave it alone - it will vanish naturally - or remove it yourself.
