Guttation: During periods of rapid growth, metabolism speeds up. In those periods some mushrooms form visible drops on their surface. This is called guttation, a term used in botany to describe the process by which plants excrete excess water through drops from their leaves. For some mushrooms this is so common that it is a reliable identification feature, while for others it is virtually unknown.
Abortiporus biennis is known for its colored guttation droplets. These are usually colored red by terphenyl quinone dye (or a derivative), a pigment produced by this genus of mushrooms. Under favorable temperature and humidity, red droplets can also be seen in other members of the genus during active growth.
Guttation is not to be confused with dew, which condenses from the atmosphere onto the surface.
