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.
Black mold is a fungus that releases toxic spoors into the air that can cause respiratory illness and irritation. The responsibility for a mold-free environment in a rental unit ultimately falls onto the landlord. Between letting tenants know about past mold history and ensuring that conditions are inhospitable for mold to grow, landlords must stay in communication with tenants about black mold protections.
