There are two slime moulds that are named for their resemblance to dogs’ vomit. One is called Dog sick (Mucilago crustacea), which starts off yellow but fades to white, then eventually looks much darker due to its mass of black spores. The key thing with this slime mould is that it grows on grass or other vegetation.

The other is Fuligo septica, commonly known as the Dog vomit or Scrambled egg slime (though, obviously, it’s not something anyone would ever want to eat, regardless of how much its yellow lumpy appearance resembles scrambled egg). Although it can look very similar to Mucilago crustacea, it grows on wood, on dead trees and branches in woodland areas but also on wood chip and bark mulches, according to the Naturespot website.

The Dog sick shown here was found in a cemetery last week; the Dog vomit image is from my photo library. (I hope you weren’t having your breakfast when you read this!)
