What are the yellow blobs growing on my Wine Cap bed?

Dog Vomit Slime Mold, or Fuligo septica, is a common slime mold that is found in the spring of the year. It can be a little alarming when it shows up on your wine cap bed or an older shiitake log but, despite it's appearance, it's quite harmless.

I prefer to call it scrambled egg mold or flowers of tan. I've seen this appear a few times on my mulch during the rainy season. I think it looks pretty. Slime molds are fascinating organisms because they exhibit rudimentary intelligence despite being protists with no neural cells. Look up some of the experiments done with slime molds, it's pretty neat.

These pop up in my woodchip mulch, during monsoon season.

good to know, just put my first Wine Cap bed in last week (from F&FP spawn) and it's rained every day since.

Very educational, good use of humor. Good job!
