Ratstail

Ratstail is a term that can refer to several distinct things, primarily a type of fungus and a slang term for a particular hairstyle.

The fungus, *Mucor racemosus*, is a common mold found in soil and decaying organic matter. It is characterized by its rapid growth and fuzzy, white colonies. In some contexts, it can be a plant pathogen, causing rot in fruits and vegetables. It is also used in the production of certain cheeses and fermented foods, though it is not as widely used as some other mold species.

As a hairstyle, "rat's tail" typically describes a long, thin section of hair left at the nape of the neck, often shaved elsewhere. This style was popular in certain subcultures and fashion trends at various times. The appearance is meant to resemble the tail of a rat. The term is generally considered informal and can carry negative connotations depending on the social context.
