Dog Vomit Slime Mold

Slime mold guessers are right! This is a slime mold — aptly-named “Dog Vomit Slime Mold” (Fuligo septica). Slime molds are not plants, animals, fungi or bacteria. This stage of a slime mold’s life cycle is called a plasmodium, which is essentially one giant cell with millions of nuclei. The plasmodium moves by slowly flowing over the ground, gradually engulfing and consuming fungi and bacteria that are present on decaying plant matter. You often find it on mulch that is regularly watered. Dog Vomit Slime Mold is harmless to people, pets and plants. In fact, it is actually edible. In some parts of Mexico people scramble it like eggs (and call it “caca de luna”).

    Thank you! This did make a startling appearance on my “regularly watered mulch,” and no one I know had a clue what it might be.

    Hi Mary – Oh my! where is Linnaeus when we need him? Dog Vomit Slime Mold indeed – almost as expressive (and apt?) as Rock Snot. And scrambled???? Yeesh! I love these – lots of them get forwarded to my daughters. Best – and keep ’em coming, please. How’s Sophie? Cheers Cordie

    • Thanks, Cordie! I must say “caca de luna” did catch my eye, especially with the blue moon last night!

  5. Think about it: you’re in the mood for a nice breakfast burrito, and you walk in to that nice little Mexican place and your mouth is watering with anticipation, and you look at the menu and find ‘caca de luna’ on it. What would the folks at Zagat have to say?

    I like both names, English and Spanish. I did refer to it as “vomitty” slime mold. Maybe next summer I’ll get up the courage to scramble it, as I do like wild gathered food. I’ll have to think up yet another mame, or maybe just the scientific one, before serving it to my husband.
