Lactarius deliciosus
Description
Lactarius deliciosus is an edible mushroom from the Russulaceae family. It can be identified by its vase-shaped body, orange and green cap with circles, and orange liquid called latex. It grows in pine forests and mixed forests all over Europe. However, recent studies show that the Lactarius deliciosus found in Europe is not the same as the ones found in North America. There are similar species in North America with the same appiriance, so more research is needed to tell them apart.
When Lactarius deliciosus is grown in a liquid culture, its mycelium produces a combination of fatty acids and different compounds like chroman-4-one, anofinic acid, 3-hydroxyacetylindole, ergosterol, and cyclic dipeptides.
Common names: Saffron Milkcap, Delicious Milkcap, Red Pine Mushroom, Netherlands (Smakelijke melkzwam).
Mushroom Identification
-
Cap
1.97 to 5.91 inches (5 to 15 cm) in diameter, convex at first, expanding and developing a central depression. It's pinkish orange with light circles around it, and when it's damaged it turns green. The surface is smooth, but it gets a little slimy when it's wet. When the mushroom is young, the flesh is firm and snaps easily. The flesh is white with some red-orange lines and specks towards the outside, where a liquid called latex comes out. The latex is orange-colored.
-
Gills
Crowded, attached or slightly decurrent, pinkish tan to orange, staining green, fragile.
-
Stem
1.18 to 1.57 inches (3 to 4 cm) long x 0.59 to 0.79 inches (1.5 to 2 cm) wide, straight and cylindrical or narrowing towards the base, hollow. The color is initially mottled white and light pinkish orange and it becomes darker orange with age. If bruised, it turns green.
-
Spores
8–11 x 7–9 µm, with net-like, interconnected ridges.
-
Spore Print
Pale yellow to buff.
-
Habitat
Lactarius deliciosus forms a special relationship with trees called mycorrhizae. It grows in acidic soil under conifer trees, such as Mediterranean pines, and can be found either solitary or scattered in groups. The mushroom fruits from late fall to mid-winter. It is a common mushroom in Europe, and many people there pick it to eat. The mushroom is different from populations found in North or Central America and has been introduced to Chile, Australia, and New Zealand, where it grows in pine tree plantations.
Look-Alikes
-
Has a smooth stem and its milk is a mild pinkish-orange color.
-
Can be recognized by its pink color, a cap margin that appears woolly, and its tendency to grow near birch trees.
Lactarius rubrilacteus
This mushroom stains blue, exudes red latex and is also edible.
Lactarius olympianus
Has white latex and tastes unpleasant.
Lactarius quieticolor
Also grows near pine. However, the cap is pale orange with a blue-green undertone and the orange spots on the stem are missing.

Cooking Notes
Before choosing any milk cap mushroom recipe, it is worth knowing that young, still tightly rolled mushrooms are especially suitable for cooking. They have very firm meat that retains its crispy consistency even with different cooking methods. Older specimens are often brittle and can be a little crumbly.
Here are some cooking notes for this mushroom:
-
Cleaning
Clean the mushrooms with a soft brush or cloth to remove any dirt or debris. Do not wash the mushrooms as they can absorb water and become soggy.
-
Cooking Methods
Saffron milk caps can be grilled, sautéed, roasted, or fried. They can also be added to soups, stews, and pasta dishes.
-
Preparing
Cut the mushroom caps into thin slices or leave them whole.
-
Flavor Pairings
Saffron milk caps pair well with garlic, onions, herbs like thyme and parsley, and acidic ingredients like lemon juice or vinegar.
-
Seasoning
Add salt and pepper to taste, but avoid adding too much salt as the mushrooms have a natural salty flavor.
-
Butter or Oil
Saffron milk caps can be cooked in butter or oil, but butter will enhance the nutty flavor of the mushroom.
-
Cooking Time
Cooking time will vary depending on the method used. Grilling or roasting will take longer than sautéing or frying.
-
Serving Suggestions
Saffron milk caps are often served as a side dish or used as a topping for pizzas or bruschetta. They can also be used in omelets or quiches.
Recipe: Catalan Saffron Milkcaps
Ingredients
-
8 oz fresh saffron milkcaps sliced if large, left whole if small
-
1/2 cup chopped peeled tomatoes
-
4 oz bulk chorizo sausage
-
2 tablespoons chopped flat leaf parsley
-
1 tsp chopped fresh garlic
-
Kosher salt and pepper to taste
-
2 tbsp extra virgin olive oil for garnishing preferably a peppery Spanish variety (optional)
-
High quality bread crust removed and toasted
Instructions
-
In a large saute pan, render the fat from the chorizo and brown it lightly. With a slotted spoon, remove the chorizo, leaving the fat in the pan.
-
Reserve the chorizo until needed.
-
Heat the remaining fat and add the saffron milkcaps. Cook the saffron milkcaps on medium-high heat until lightly browned and caramelized, about 5 minutes. Season the mushrooms lightly with salt.
-
Add the garlic, stir and cook for 1 minute. Add the tomatoes, reserved chorizo and parsley and cook for 5 minutes more. Double check the seasoning for salt and pepper, then serve immediately on toast garnished with a drizzle of the olive oil.
Recipe: Polish Salted Mushrooms
Ingredients
-
3 to 4 pounds fresh mushrooms, cleaned and stems removed
-
Kosher or pickling salt
-
6 to 10 juniper berries, crushed (optional)
-
1 teaspoon dried dill, or 2 tablespoons fresh
-
1 teaspoon caraway seed
-
2 teaspoons cracked black pepper
-
2 garlic cloves smashed
Instructions
-
Boil the mushrooms in salted water for 5 minutes. Drain and let them cool in one layer on a paper towel or tea towel.
-
Mix all the herbs and spices in a small bowl. Lay down a thin layer of pickling or kosher salt at the bottom of a crock or other non-reactive container, then lay down a layer of mushrooms. Sprinkle with some of the herbs and spices. Add a bit more salt. Keep layering like this until you have all the mushrooms in the crock. Finish with another layer of salt.
-
Place a clean plate or other top on the mushrooms and weigh it down. I use a quart Mason jar filled with water. Let this sit in a cool, dark place (no need to refrigerate) for 4 days. After the first day, check to see that the mushrooms are submerged in their own brine. If not, boil 1 pint of water with 2 tablespoons kosher salt and let it cool. Pour over the mushrooms and continue fermenting.
-
After 4 days, move the mushrooms and brine and spices to clean Mason jars and refrigerate. They will keep for several months.
Recipe: Saffron Milk Cap Mushroom Tart
For pastry
-
2 cups plain all purpose flour
-
150g/5ozs. butter, cubed and cold
-
1 cup finely grated parmesan cheese
-
1/2 teaspoon fine salt
-
1 egg
-
1/2-2/3 cup ice water
For filling
-
5 saffron milk cap mushrooms in various sizes
-
4 cloves garlic, peeled and sliced
-
Extra virgin olive oil for frying
-
150g/5ozs. ash brie, sliced (I used one with ash in the centre)
-
3 eggs
-
1 cup cream
-
1 cup parmesan cheese
-
2 sprigs thyme
Instructions
-
First make the pastry as it needs to rest. Place the flour, butter, cheese and salt in a food processor and pulse to combine. Add the egg and 1/2 cup of water and process until it starts to come together. Knead it on a floured surface adding a bit more water if it needs it to become a cohesive dough. Cover with clingfilm and allow to rest at room temperature for 30 minutes.
-
Spray a 31x21cm tart tin with a loose bottom with oil spray. Flour a surface and rolling pin and roll out the dough so that it can fit your tart tin and trim off any overhang. Place in the fridge for 45 minutes or freezer for 15 minutes.
-
While it is resting, cook the mushrooms. Keep the smaller, more pristine looking ones whole and slice up the rest. Add the oil to a frypan on medium heat and cook the garlic and then the mushrooms. They should still retain a bright orange color. Season with salt and pepper and set aside to cool slightly.
-
When the pastry has rested, preheat oven to 200C/400F and spray a sheet of foil with oil and press it gently against the pastry. Fill with baking weights or dried beans or rice and bake for 20 minutes. Carefully remove the foil with beans and bake for another 10-15 minutes or until cooked.
-
Reduce oven heat to 150C/300F. Whisk the eggs and cream together with the parmesan cheese. Pour into the baked tart case and then top with the mushrooms and brie slices. Place the thyme on top and carefully move to the oven (try not to splash the cream mix onto the mushrooms). Bake for 30-35 minutes or until just set. Serve warm.

History
In 1753 Swedish scientist Carl Linnaeus described this mushroom and named it Agaricus deliciosus. At that time, many mushrooms were grouped together in a genus called Agaricus. Later, in 1821, a British scientist named Samuel Frederick Gray gave the mushroom a new name: Lactarius deliciosus.
The name "Lactarius" refers to the fact that these mushrooms produce a milky substance when they are cut or torn. The milky substance is called latex, and different types of milkcap mushrooms produce different amounts of it.
The name "deliciosus" tells us that Carl Linnaeus thought this mushroom was delicious to eat.
