History

In 1818 Elias Magnus Fries gave it the scientific name Agaricus cetratus. The currently-accepted scientific name Entoloma cetratum dates from a 1978 publication by Austrian mycologist Meinhard Michael Moser (1924 - 2002).

The generic name Entoloma comes from ancient Greek words entos, meaning inner, and lóma, meaning a fringe or a hem. It is a reference to the inrolled margins of many of the mushrooms in this genus.

The specific epithet cetratum comes from the Latin cetra or caetra, meaning a small liught shield.
