Ellyllon

The ellyllon (singular: ellyll) are one of the five varieties of tylwyth teg, or Welsh fairies. The ellyllon variety are the Welsh version of elves, and are also known simply as "Welsh elves" or "Welsh pygmies" due to their small stature.

Description
The ellyllon are small elves that are considered to be smaller in size than the typical tylwyth teg. They reside in hidden groves and valleys. They are known for wearing gloves made from the bells of the foxglove flower, whose leaves are known in traditional medicine as a potent sedative.

According to folklore, the ellyllon are known for eating certain kinds of fungi. They have been attested to eating poisonous mushrooms and toadstools, along with a strange fungus known as "fairy butter," which is found in limestone crevices and on the roots of rotted trees.

Ellyllon are known for possessing magical abilities, which can be used to either help or harm humans depending on the temperament of the individual ellyll. They are generally considered to be solitary elves, but are ruled by a queen named Queen Mab.
