Saffron milk caps

Saffron milk cap and bloody milk caps: recognising them by their orange or red milk, telling them from the woolly milk cap, their pine forests and their autumn season.

In brief

In Sporalo, the saffron milk caps season opens around 10 August, peak season runs from 15 October to 10 November and it ends around 11 December (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: Woolly milk cap (toxic). If in doubt, show your harvest to a pharmacist or a mycological society; if you have symptoms, call 15 or 112.

Recognising milk caps

Several coloured-milk milk caps, all edible, are picked under this name:

  • the saffron milk cap (Lactarius deliciosus), orange cap with concentric rings, carrot-orange milk, under pines;
  • the bloody milk cap (L. sanguifluus) and its relatives, with wine-red milk, under pines in the south;
  • the spruce milk cap (L. deterrimus) and the salmon milk cap (L. salmonicolor, under fir), less good to eat.

All turn green with age or when touched. The coloured milk, which beads at the break, is the deciding criterion.

Simple rule: break a gill. The milk must be orange or red, never white. A milk cap with white milk does not belong to this group. Also beware of the yellow-milk milk cap (L. chrysorrheus, under oaks), whose white milk turns yellow: it is toxic.

Habitat: where to look

The saffron milk cap is tied only to pines: no pines, no saffron milk caps.

Under which trees

  • Pines: Scots, black, maritime, Aleppo. Pine woods are the classic ground, young and mature alike.
  • The spruce milk cap and the salmon milk cap are tied to spruces and firs. Sporalo's map only takes pines into account.

Terrain and aspect

  • A mushroom of dry, warm woods: very common around the Mediterranean in autumn, rarer as you go up in latitude. No precise altitude is given by the sources consulted.
  • No aspect preference is established: above all look for the pine wood.

Soil

  • Rather indifferent to soil acidity and texture: it is found on acidic as well as calcareous soil. A form with reddening milk is reported on calcium-rich soils.
  • A well-drained soil, carpeted with needles and short grass, suits it well.

Microsites: where to look

  • In the grass and needles of young pine woods, on banks, edges and track verges.
  • Often in groups, sometimes in moss under pines.
  • Lift the needles: young ones hide underneath. Mature ones are often wormy: pick them young.

Season and triggers

In autumn, later on the Mediterranean coast. It generally comes up one to two weeks after good rain as long as nights stay mild. Specimens are often wormy: they are picked young.

Frequently asked questions

When do saffron milk caps grow in France?

In Sporalo, the saffron milk caps season opens around 10 August, peak season runs from 15 October to 10 November and it ends around 11 December (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 saffron milk caps be confused with?

Main look-alikes: Woolly milk cap (toxic). 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 saffron milk cap?

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.
