Rimose

Rimose mushroom (Inosperma rimosum)

Rimose is an adjective used to describe a surface that is cracked or fissured.^[1]

The term is often used in describing crustose lichens.^[1] A rimose surface of a lichen is sometimes contrasted to the surface being areolate.^[1] Areolate is an extreme form of being rimose, where the cracks or fissures are so deep that they create island-like pieces called areoles, which look the "islands" of mud on the surface of a dry lake bed.^[1] Rimose and areolate are contrasted with being verrucose, or "warty".^[1] Verrucose surfaces have warty bumps which are distinct, but not separated by cracks.^[1]

In mycology the term describes mushrooms whose caps crack in a radial pattern, as commonly found in the genera Inocybe and Inosperma.^[2]
