Wood blewits

Wood blewit (Lepista nuda): recognising it by its lilac colour and fruity smell, avoiding violet webcaps and fibrecaps, its broadleaf litter and its late season.

In brief

In Sporalo, the wood blewits season opens around 15 September, peak season runs from 15 October to 15 December and it ends around 15 January (lowlands, central France). Dates move earlier or later depending on altitude, latitude and above all the weather: growth follows rain and mild weather.

Main look-alikes: Lilac bonnet (toxic), Lilac fibrecap (toxic) and Gassy webcap (inedible). If in doubt, show your harvest to a pharmacist or a mycological society; if you have symptoms, call 15 or 112.

Recognising the wood blewit

The wood blewit (Lepista nuda) is one of the last mushrooms of the year:

  • lilac to violet-brown cap, smooth, fleshy;
  • violet gills, crowded, which separate easily from the flesh;
  • violet, fibrous stem, with no ring or veil;
  • pleasant fruity smell, pale pink spore print (not rust-coloured).

Look-alikes

Petites mycènes roses à lilas au pied fin
Toxic Lilac bonnet Mycena pura

Smaller and fragile, brittle hollow stem, smell of radish. Contains muscarine.

Petits inocybes lilas au chapeau conique
Toxic Lilac fibrecap Inocybe geophylla var. lilacina

Small conical, silky lilac cap, brownish gills, spermatic smell. Muscarine.

Inedible Gassy webcap Cortinarius traganus

Also violet, but with a cobweb-like veil, rust-coloured gills and a strong smell of acetylene. Violet webcaps are to be excluded.

Simple rule: never a cobweb-like veil under the cap, never rust-coloured gills, fruity smell. Small violet or lilac mushrooms with a thin stem are not wood blewits. Always have it checked if in doubt.

Habitat: where to look

The wood blewit has no host tree: it decomposes dead plant matter (leaves, twigs, needles). So it is found where litter builds up.

Which habitat

  • Broadleaf and conifer woods alike, edges, hedgerows, parks.
  • One variety grows rather outside woods, in meadows and pastures enriched by livestock.
  • Heaps of leaves or compost also suit it.
  • Ploughed land and built-up areas do not suit it.

Terrain and soil

  • No precise altitude, aspect or acidity is established by the sources consulted (Sporalo does not take pH into account for it). Above all look for a thick layer of fresh, decomposing litter.

Microsites: where to look

  • In the thickness of dead leaves, at the edge, at the foot of hedges, along tracks.
  • In often numerous troops, frequently in circles (“fairy rings”) or lines: if you find one, look around.
  • It comes up after the first cold weather, when many other mushrooms have finished.

Caution: other violet or lilac mushrooms, some of them toxic, can grow in the same kind of litter: the place alone is not enough to tell them apart, check every specimen (see “Look-alikes”).

Season and triggers

From autumn to early winter. It likes damp cold and tolerates the first frosts, unlike most species. It is always eaten well cooked.

Sources

The months and periods mentioned are rules of thumb for metropolitan France, not quantified results from a study: the site's calculation is based on the weather (see the method). No published study on the wood blewit was retained to support figures: this page therefore gives none. Habitat: Wikipédia (French), « Pied bleu » (secondary summary, consulted in November 2026), fr.wikipedia.org/wiki/Lepista_nuda: broadleaf and conifer woods, decomposing plant matter, meadow and pasture variety, compost, numerous troops, fairy rings, after the first cold weather.

Frequently asked questions

When do wood blewits grow in France?

In Sporalo, the wood blewits season opens around 15 September, peak season runs from 15 October to 15 December and it ends around 15 January (lowlands, central France). Dates move earlier or later depending on altitude, latitude and above all the weather: growth follows rain and mild weather.

What can wood blewits be confused with?

Main look-alikes: Lilac bonnet (toxic), Lilac fibrecap (toxic) and Gassy webcap (inedible). If in doubt, show your harvest to a pharmacist or a mycological society; if you have symptoms, call 15 or 112.

Can Sporalo identify a wood blewit?

No. Sporalo measures growing conditions (weather, forest, soil); it does not identify mushrooms. Never eat a mushroom without certain identification. If in doubt, show your harvest to a pharmacist or a mycological society; if you have symptoms, call 15 or 112.
