Description

An orange milkcap under spruce with orange latex that later darkens wine-red.

Identification features

Damaged areas often turn strongly green and the cap is zoned. The host tree also helps distinguish it from other orange milkcaps.

Identification checklist

The cap is orange and zoned, often showing green patches even when young. Crowded orange gills release orange latex that turns wine-red within about half an hour and later dark green. The smooth stem lacks orange pits, and the species is almost always associated with spruce.

Detailed features

Cap
5–10 cm, orange to carrot-orange, often zoned; distinctly greening with age and bruising.
Hymenophore
Gills are orange, crowded, somewhat decurrent and turn green when bruised.
Stem
5–8 × 1–1.5 cm, orange, becoming hollow; usually without conspicuous pits, sometimes with reddish marks.
Flesh
Pale orange; damaged tissue exudes orange latex that later turns wine-red, and bruised areas may green.
Smell
Mild to fruity-mushroom-like.
Spore print
Pale ochre.

Size

Cap diameter
5–10 cm
Stem height
5–8 cm
Stem diameter
1–1,5 cm

Habitat

Almost exclusively with spruce, in spruce and mixed woodland.

Fruiting period

July, August, September, October, November

Ecology

Trophic mode
Mycorrhizal
Host trees
Spruce (Picea)
Substrate
Forest soil
Notes
Mycorrhizal almost exclusively with spruce, in spruce and mixed woodland and along their edges.

Distribution

Notes
In Europe it broadly follows the distribution of spruce and can be locally common in spruce stands.

How to separate similar species

Saffron milkcap grows mainly with pine, has shallow orange pits on the stem, and usually shows fewer green patches when young. Woolly milkcap has a pink cap with a woolly margin, white latex, and grows with birch.

Similar species

  • Saffron milk cap (Lactarius deliciosus)

    Saffron milkcap is more strongly associated with pine and often has conspicuous stem pits; false saffron milkcap is spruce-associated and greens more strongly.

Interesting facts

Did you know? The strong greening after damage results from chemical changes in pigments in the latex and tissues.
