How to identify Beech Milkcap

To correctly identify Beech Milkcap (Lactarius blennius), check each of these features in order. Misidentification is the most common cause of mushroom poisoning, so cross-reference multiple sources.

Step-by-step identification

1. 1

   Cap

   Shape, color, surface texture, and diameter.

   The cap is convex to flattened, often with a slightly depressed center. The surface is smooth and slightly sticky when moist. The color ranges from pale ochre to tan, sometimes with faint concentric zones.

2. 2

   Gills

   Attachment to stem, color, and spacing.

   The gills are crowded and decurrent, meaning they run down the stem. They are typically pale cream to ochre in color.

3. 3

   Stem

   Length, shape, surface, and any ring.

   The stem is cylindrical, smooth, and typically the same color as the cap or slightly paler. It is usually 3 to 7 cm long and 1 to 2 cm thick.

4. 4

   Flesh

   Color, texture, and bruising reaction.

   The flesh is whitish and firm. When cut, it exudes a milky latex that is initially white but slowly turns yellow upon exposure to air.

5. 5

   Fruiting body

   Overall growth pattern.

   The fruiting body of Lactarius blennius is a mushroom with a cap and stem. The overall size is medium, with the cap typically ranging from 5 to 10 cm in diameter.

6. 6

   Habitat

   Where it grows and on what substrate.

   Lactarius blennius is found primarily in Europe, associated with beech trees. It typically grows in deciduous forests, often near or under beech trees.
