Charbonnier (Tricholoma portentosum): where and when it grows

The mushroom of the cold. When nothing is left in the pine wood, it keeps coming up.

Charbonniers on a frosty late-autumn morning: grey cap with dark fibres, whitish gills and a white stem with touches of lemon yellow.

The charbonnier (Tricholoma portentosum) comes out from October to January, at its best in November, in woods of Scots pine, maritime pine, Aleppo pine, black pine and mountain pine, from low ground up to the middle mountains. It is also known as sooty head.

See where it is ready this week

No area is ready for charbonniers this week: the forest is still asleep.

The charbonnier is the last good mushroom of the year in the pine woods: it comes up in November and December, with the first frosts, when saffron milk caps and porcini have already gone. Grey, slippery and sweet-fleshed, it is the reward for those who keep going out to the woods when others have stopped.

It wants damp, cold soil and withstands the frosts that kill the others. The map follows it in the pine-wood areas when the soil temperature drops below ten degrees.

What it needs to come out

First, a good rain, the kind that soaks the ground. Then patience: it usually appears after two or three weeks, as long as the soil holds on to that moisture and stays cold, without freezing. If a frost, too much water or a drying wind comes in between, the flush is aborted and never shows.

Where to look

It comes out in woods of Scots pine, maritime pine, Aleppo pine, black pine and mountain pine, from low ground up to the middle mountains, without being fussy about the soil.
