Water Sprite. Water sprites are said to be able to breathe water or air, and in some cases, can fly. They are mostly harmless unless threatened. These creatures exist in mythology of various groups. Ancient Greeks knew water nymphs in several types such as naiads (or nyads), which guarded the fresh water bodies for the gods, while Slavic mythology knows them as vilas.
Yellow mold is a fungus that normally grows in dark and damp places. Several species of this mold exist, with some belonging in genera that are toxic or widely known to destroy wood. It is usually obvious when a building has a yellow mold infestation because the mold's color is often bright and difficult to miss.
Yellow mold on top of my mulch? I am a new homeowner and therefore new to gardening. This is my first spring in our house. We have mulch covering a number of flower bed on our backyard. One day, after a heavy rain, I noticed a moist yellow pile laying on top of some of the mulch. My first though was that some mammal (a racoon or skunk) had gotten sick adn thrown up. After a day the moist yellow curd became a slightly puff orange/peach colored mass, then became grey and wilted.
