A. You are describing a slime mold, possibly scrambled egg slime (Fuligo septica), though it could be any of several species common on wood litter in wet weather.

The first description of the species was provided by French botanist Jean Marchant in 1727, who referred to it as "flowers of tan"; Marchant classified it as a "sponge".
