Lactarius deliciosus: The Ultimate Mushroom Guide

About The Lactarius deliciosus Mushroom

Lactarius deliciosus is an edible mushroom from the russulaceae family. It’s grows on pine groves and mixed forests. The mushroom emerges in autumn and it’s highly valued in cooking.

It belongs to the Lactars or milk-bearing group. As a group the milk-bearing mushrooms are generally viewed with suspicion, but the species deliciosus receives general commendation as an esculent. It is easily distinguished from any other of the group by the orange or red color of the milk which exudes from it when cut or broken.

The flesh changes on exposure to the atmosphere, as does the milk also, and becomes a dull green color.

The flavor of Lactarius deliciosus when cooked is said to resemble that of "kidney stew".

The Saffron milkcap is pretty much the national mushroom of Spain, where it’s known as the “rovellon”, or in other regions as the “niscalo”.

Common Names: Saffron milkcap, Delicious milkcap, Red Pine mushroom.

Lactarius deliciosus Identification

1. Taste

   Slightly acrid. (Briefly taste a pea-sized piece then spit it out.)

2. Cap

   5–15 cm in diameter, convex at first, expanding and developing a central depression. The color is pinkish orange with concentric rings of lighter fibrils. Where bruised, the cap turns green.

   The surface is smooth, fibrillose when dry, slightly viscid when wet. Flesh of cap and stem are crisp when young and the mushroom breaks with a snap.

   The flesh is whitish with reddish-orange lines and flecks toward the outside where latex is being produced.

3. Gills

   Crowded, attached or slightly decurrent, pinkish tan to orange, staining green, fragile.

4. Latex

   Orange then staining green.

5. Stem

   3–4 cm long x 1.5–2 cm wide, straight and cylindrical or narrowing towards the base, hollow. The colour is initially mottled white and light pinkish orange and it becomes darker orange with age. If bruised, it turns green.

6. Spores

   8–11 x 7–9 µm, with net-like, interconnected ridges.

7. Habitat

   Solitary, scattered to gregarious under pines; fruiting from late fall to mid-winter. This mushroom is common in Europe and many people there pick them to eat.

Lactarius deliciosus Look-Alikes

There are no lookalikes to Lactarius deliciosus mushroom with all the characteristics mentioned above.

However, there are many orange mushrooms that may at first confuse a novice eager to find.

Please use this reference as a tool for identification only and never eat any mushroom unless you do your research and you are 100% sure. Remember if in doubt leave it out!

Lactarius deliciosus Cultivation

First of all, you need to buy or get from the mushroom spore print. Also, you can buy ready for injection mycelium and follow the next steps:

1. Draw a line on the ground around the chosen tree, that follows the margin of its canopy.

2. For young pine (4-6 years), make a furrow(10-15 cms depth) following the line and fold back the earth. In older pines you have to make 8-12 holes along this line. Where there is grass, this can be removed before seeding and left back again after seeding.

3. Dissolve the content of the bag in one litre of water, shake it & allow to rest for 10 minutes. Distribute the resulting gel in the furrow or in the holes.& cover with earth.

4. Water the first day but do not flood; thereafter keep moist.

Maintenance and gathering:

Water in dry periods during the summer Do not work the soil thereafter and avoid walking over the area. Do not fertilize.

Production, about 800g each season, should begin in about 2 years after seeding.

Repeat the sowing every two years to maintain production.

Lactarius deliciosus Taxonomy & Etymology

This mushroom was described in 1753 by Carl Linnaeus, who gave it the binomial scientific name Agaricus deliciosus. (In the early days of fungal taxonomy most gilled fungi were initially placed in a giant Agaricus genus, now largely redistributed across many other genera.) The currently-accepted scientific name Lactarius deliciosus dates from an 1821 publication by British mycologist Samuel Frederick Gray (1766-1828).

Synonyms of Lactarius deliciosus include Agaricus deliciosus L., and Agaricus lactifluus var. deliciosus (L.) Pers.

The generic name Lactarius means producing milk (lactating) - a reference to the milky latex that is exuded from the gills of milkcap fungi when they are cut or torn - although some species provide a lot more milk than others do, and the Saffron Milkcap Lactarius deliciosus is very variable in this respect.

The specific epithet deliciosus is clear evidence that Carl Linnaeus had more than a scientific interest in fungi and that he considered the Saffron Milkcap to be delicious to eat.

Recipe: Catalan Saffron Milkcaps

Ingredients

1. 8 oz fresh saffron milkcaps sliced if large, left whole if small

2. 1/2 cup chopped peeled tomatoes

3. 4 oz bulk chorizo sausage

4. 2 tablespoons chopped flat leaf parsley

5. 1 tsp chopped fresh garlic

6. Kosher salt and pepper to taste

7. 2 tbsp extra virgin olive oil for garnishing preferably a peppery Spanish variety (optional)

8. High quality bread crust removed and toasted

Instructions

1. 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.

2. Reserve the chorizo until needed.

3. 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.

4. 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

1. 3 to 4 pounds fresh mushrooms, cleaned and stems removed

2. Kosher or pickling salt

3. 6 to 10 juniper berries, crushed (optional)

4. 1 teaspoon dried dill, or 2 tablespoons fresh

5. 1 teaspoon caraway seed

6. 2 teaspoons cracked black pepper

7. 2 garlic cloves smashed

Instructions

1. Boil the mushrooms in salted water for 5 minutes. Drain and let them cool in one layer on a paper towel or tea towel.

2. 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.

3. 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.

4. 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

1. 2 cups plain all purpose flour

2. 150g/5ozs. butter, cubed and cold

3. 1 cup finely grated parmesan cheese

4. 1/2 teaspoon fine salt

5. 1 egg

6. 1/2-2/3 cup ice water

For filling

1. 5 saffron milk cap mushrooms in various sizes

2. 4 cloves garlic, peeled and sliced

3. Extra virgin olive oil for frying

4. 150g/5ozs. ash brie, sliced (I used one with ash in the centre)

5. 3 eggs

6. 1 cup cream

7. 1 cup parmesan cheese

8. 2 sprigs thyme

Instructions

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.
