Accessory clouds
An accessory cloud is a cloud accompanying or adjacent cloud mass to another cloud, generally smaller than the latter, and separated from its principal part, usually a major cloud genus (or type) or sometimes partially merged with it.

arcus (arc) - arch, shelf, roll or
wall cloud
incus (inc) - anvil
mamma (mam) - pouches hanging from underneath main clouds
