Old fire places, burnt forests, offer a special habitat, surprisingly favorable to many fungi. L’Omphale des Charbonnières, Myxomphalia maura, finds its place. This Basidiomycète from family Mycenaceae will meet from spring to autumn.

Description of Omphale des charbonnières

L’Omphale des charbonnières has a hat heavily hollowed out in the center, the size of which varies between 1 and 5 cm in diameter. Its surface tends towards rather dark brownish or grayish tints but hygrophane it evolves towards pale gray in dry weather. The gelatinous and elastic cuticle is easily removable. The margin is coiled and slightly ridged in young subjects. Whitish to pale gray, the blades are not very decurrent, broad and fairly tight.

Although it is sometimes paler, especially at the apex, the foot is brownish to greyish, concolore in the hat. Measuring between 2 cm and 6 cm in height, it is initially finely pruinose and quickly becomes smooth and shiny. The whitish to greyish-creamy flesh is tough but often thin in the cap. Its flavor and smell are sweet but with a slight floury tendency.

Determination of Myxomphalia maura

The characteristic living environment of Myxomphalia maura, on the old fire places, limits the risk of confusion. However this species shares its habitat with other fungi, more or less close. Such as False chanterelle, Faerberia carbonaria, which is uncommon and has less tight blades, very decurrent on the foot and forked, resembling the folds of Chanterelles.

Another confusion is possible with a rare species, Lyophyllum ambustum which looks a lot like him but whose blades are darker and thinner. In addition, its cuticle is not gelatinous and its hat is sometimes less hollowed out. However, in order to differentiate them with certainty, a study of the spores under a microscope is essential.

Living environment

This uncommon species appreciates the old places of fire, it thus develops on the coal mines, in particular on the burnt wood of conifer. It grows most often in the company of other individuals but can also be seen alone. Its growth period extends mainly from May to October.

Toxicity or culinary interest of the omphale

Inedible. Its flavor without much culinary interest and its specific distribution within the fire places does not favor its consumption.

Species and varieties of Myxomphalia

Many Omphales grow among mosses:

  • Arrhenia gerardiana : brown-gray hat, in peat bog mosses
  • Arrhenia rickenii : Ricken’s Omphale, greyish to brownish cap, in moss of lawns and stones
  • Arrhenia velutipes : Omphale with velvety foot, blackish-brown hat then gray-brown, in mosses or on fire places
  • Omphalina rivulicola : Omphale of streams, reddish-brown, in mountain mosses
  • Rickenella fibula : Omphale in needle, yellow-orange hat, in mosses of meadows and forests
  • Rickenella swartzii : Swartz’s Omphale, blackish-brown hat, in mosses of meadows and forests
