Saffron milk caps: where they grow now and when

The king of the pine woods. Orange, stubborn and generous when its moment comes.

Saffron milk caps in a pine wood: orange cap with darker rings and the odd green stain, orange gills, a hollow stem and carrot-coloured milk.

The saffron milk cap (Lactarius deliciosus / Lactarius sanguifluus) comes out from September to January, at its best in October, 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 red pine mushroom.

Right now, the best day forecast for saffron milk caps is 15 September.

The saffron milk cap is the family mushroom: the one people look for in groups, the one you recognise without fear and the one that fills the basket when autumn does its job. It lives under pines, from the coast to the mountains, and that is why its season is long: in the ranges it starts with the first September rains and on the coast it stretches into January.

It needs three things: a rain that soaks in, soil that holds it for a couple of weeks and ground that has cooled down without freezing. When they come together, it comes up in droves. When one is missing, it does not, however much it rains. Every day the map shows in which areas they are coming together.

What it needs to come out

First, a good rain, the kind that soaks the ground. Then patience: it usually appears after three or four weeks, as long as the soil holds on to that moisture and stays mild. 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.
