Entoloma papillatum (Bres.) Dennis - Papillate Pinkgill

Phylum: Basidiomycota - Class: Agaricomycetes - Order: Agaricales - Family: Entolomataceae

Entoloma papillatum - Papillate Pinkgill , France

Despite its scientific and common names, Entoloma papillatum is by no means the only 'papillate' (with a nipple-like raised projection in the centre of its cap) pinkgill. For this reason it is not a species that many people will ever be able to identify with confidence in the field.

The specimens shown in the shown on this page have been independently verified by microscopic examination of spores and of samples of gill and cap tissue.

Entoloma papillatum - Papillate Pinkgill , England


The Papillate Pinkgill is an uncommon to rare find in Britain and Ireland; it occurs throughout mainland Europe, where it is also quite rare.

Taxonomic history

This uncommon mushroom was described scientifically in 1887 by the Italian mycologist Giacopo Bresadola (1847 - 1929), who gave it the name Nolanea papillata.

It was the British mycologist Richard William George Dennis (1910 - 2003) who, in 1953, transferred this species to its current genus, at which point its binomial scientific name became Entoloma papillatum.

Synonyms of Entoloma papillatum include Nolonea papillata Bres., Nolanea mammosa ssp. papillata (Bres.) Konrad & Maubl., and Rhodophyllus papillatus (Bres.) J. E. Lange.


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 papillatum means papillate - having a small nipple-like projection. (In mammals, the nipples of the mammary glands are known as papillae.)

Culinary Notes

Entoloma papillatum is too rare to be collected for anything but essential research. (It is also thin-fleshed and insubstantial.)
