Cuphophyllus flavipes (Britzelm.) Bon - Yellow-foot Waxcap

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

Cuphophyllus flavipes

A fairly common but localised waxcap fungus, Cuphophyllus flavipes is recognisable by its arching gills and the yellow surface of its lower stem.


Cuphophyllus flavipes is a relatively common waxcap species in Britain, Ireland and most of northern Europe, with occasional records from as far south as northern Spain. The specimens illustrated on this page were found in a village churchyard in West Wales.

Taxonomic history

Cuphophyllus flavipes is a waxcap whose basionym dates from an 1891 publication by German mycologist Max Britzelmayr (1839 - 1909), who gave it the scientific name Hygrophorus flavipes. The currently-accepted scientic name Cuphophyllus flavipes dates from a 1985 publication by French mycologist Marcel Bon (1925 - 2014).

Synonyms of Cuphophyllus flavipes include Hygrophorus flavipes Britzelm., Hygrocybe flavipes (Britzelm.) Bon, and Camarophyllus flavipes (Britzelm.) Clémençon.


The genus Cuphophyllus was described in 1985 by French mycologist Marcel Bon. The prefix Cupho- means curved, while the suffix -phyllus refers to the leaves (gills) of mushrooms in this genus - so we arrive at 'with curved gills'. (Its former genus Hygrocybe is so named because fungi in this group are always very moist. Hygrocybe means 'watery head'.)

The specific epithet flavipes means 'with a yellow foot' - a reference to the colour of the lower part of the stem of this grassland mushroom.

Cap of Cuphophyllus flavipes


Convex when young, then flattening, often with a low broad umbo and sometimes slightly infundibuliform (shallowly funnelled) with upturned margins when mature, caps range from 1 to 4cm across; sticky and usually greasy or slightly slimy in wet weather; translucently striate over most of the cap; colour variable from greyish through violaceous grey-brown, darker towards the centre; hygrophanous, turning pale pinkish buff from the centre in dry weather.

Gills of Cuphophyllus flavipes


Arched, decurrent, interveined, the grey gills have paler margins and are widely spaced.

Basidia mostly four spored.

Stem of Cuphophyllus flavipes


White or very pale grey at the apex, becoming yellow towards the base; cylindrical but usually tapering at the base; longitudinally fibrillose; no stem ring.

Spores of Cuphophyllus flavipes


Subglobose to lacrimose (teardrop shaped) or broadly ellipsoidal, smooth; 5.5-7.5 x 5-6μm; hyaline; inamyloid.

Not distinctive.

Habitat & Ecological role

Mainly in unimproved grassland such as old lawns and churchyards.

Waxcaps have long been considered to be saprobic on the dead roots of grasses and other grassland plants, but it is now considered likely that there is some kind of mutual relationship between waxcaps and mosses.


August to November in Britain and Ireland.

Similar species

Gliophorus irrigatus is brownish but much more slimy.

Culinary Notes

Cuphophyllus flavipes is not generally considered to be a culinary collectible.
