Field blewit: when to pick and how to tell

The field blewit is hard to mistake for anything else: it has a pale cap and a bright lilac-violet stem, as if the mushroom had been dipped in paint. It is a tasty late-autumn mushroom, prized precisely when most others are already gone. Let's look at where and when to find it, how to recognize it and what makes it valuable.

What the field blewit looks like

The main features of the field blewit:

Stem thick, firm, bright lilac or lilac-violet — this is the key feature.
Cap fleshy, smooth, grayish-cream or pale ocher, up to 15 cm.
Gills crowded, cream or pale yellowish.
Smell pleasant, fresh, slightly fruity.

Where and when to pick the field blewit

The field blewit is a mushroom of late autumn: it appears in September and fruits abundantly in October–November, right up to the first frosts. It loves cool weather and isn't afraid of light frosts.

It grows on forest edges, in clearings, orchards, shelterbelts and pastures — often in rows or rings on grassy, fertile soils. Like other late mushrooms, it hangs on when the season is already fading — more on that in the article when the mushroom season ends.

How not to misidentify the field blewit

The lilac stem makes the field blewit fairly recognizable, but caution is always needed. You can mistake it for other violet knights and blewits or for webcaps — and some webcaps are poisonous. So go by all the features together: a pale cap, crowded cream gills, a pleasant smell, and a lilac stem only — not violet all over, cap and stem alike.

The general safety rule is the same: only take mushrooms you are sure about. How identification by all the features works is explained in the article myths about recognizing poisonous mushrooms.

What makes the field blewit worthwhile

People love the field blewit for its firm, meaty flesh and for rarely being wormy. It is conditionally edible: it must be boiled before frying or pickling. Like most mushrooms, the field blewit must not be eaten raw — more on that in the article which mushrooms you can eat raw.
