pellis

The term pellis refers to the cellular cortical layers of a mushroom. The term was introduced by Dutch mycologist Cornelis Bas in 1969, who distinguished different layers of the pellis as suprapellis, mediopellis and subpellis.{{cite journal |last=Bas C.|year=1969|title=Morphology and subdivision of Amanita and a monograph on its section Lepidella |journal=Persoonia|volume=5|pages=285–579}} He also distinguished various topographies of the pellis. For example, pileipellis refers to the cuticle of the mushroom pileus (or cap), while stipitipellis is the cuticle of the stipe (the stem).
