The gray mountain milkling ( Lactarius lepidotus ) is a type of mushroom from the family of the deaf relatives . It is a small milkling with a gray, velvety to finely scaly hat that grows in alpine green alder thickets. The white, unchanging milk tastes hot.

Macroscopic features
The 1–3.2 cm wide hat is flat arched when young and later flattened to deepened in a funnel shape. The hat usually has a small hump in the middle. The surface is fine and velvety when young, matt and later increasingly flaky when pressed down. The hat is grayish brown when young and lighter gray to cream-beige with age and has small, concentrically arranged, brown scales. The edge is smooth and inflected when young and somewhat grooved to weakly torn with age.
The young whitish, later cream-colored lamellae are broad and run down a little on the stem. Some of the lamellas can be forked, the edges are smooth.
The 1.2–3 cm long and 0.3–0.5 cm wide, cylindrical stem is full, the surface is smooth and light reddish-ocher. At the base, the stalk is cream-colored to whitish and when it is young it is faintly whitish frosted over its entire length.
The whitish flesh smells faintly and tastes just as pungent as the white, unchangeable milk.
Microscopic features
The rounded to elliptical spores are 6.7–9.1 µm long and 5.6–7.4 µm wide. The Q value (quotient of spore length and width) is 1.1–1.3. The spore ornament is up to 0.8 µm high and consists of individual warts and ribs that are almost completely connected like a network.
The club-shaped to bulbous, mostly four-pored basidia are 36–45 µm long and 9–11 µm wide. The numerous cheilomacrocystids are spindle-shaped to awl-shaped and measure 35–55 × 4–7 µm. The 40–95 µm long and 7–9 µm wide pleuromacrocystids are similar, but less numerous.
The hat skin ( Pileipellis ) consists of irregularly intertwined, 6–17 µm wide hyphae and individual, protruding hyphae tufts. Individual lactifera are found between the hyphae .
Species delimitation
The Milchling can usually be easily recognized. The gray-brown, finely-scaled hat and the occurrence of green alder are two characteristic features. A confusion would only be possible with the brown green alder milkling ( Lactarius brunneohepaticus ), which, as the name suggests, also grows in green alder. But this one has a brown, darker hat and is not scaly. In addition, its milk is mild and turns yellow when exposed to air.
Distribution and ecology
The Milchling was found in North America and Europe. The montane to alpine species usually grow socially in stocks of green alder, especially on soils that are rich in bases. The Milchling is very rare in Germany, common in Switzerland, but not common.
Systematics
The Milchling was first described by Hesler and AHSmith in 1979. As taxonomic synonyms apply Lactarius griseus within the meaning of Kuhner (1928) and many other authors and Lactarius pusillus within the meaning of Neuhoff (1956). The species is not synonymous with L. griseus in the Peck sense . The type attribute ( epithet ) derived from the Greek (lepidotós ) lepidotus means scaly.
Inquiry systematics
Basso places the Milchling in the Colorati section, which is itself within the Russularia subgenus . The representatives of the subsection have dry, more or less flaky to felty hats. The milk is white or watery and invariable in the air. The spores are more or less ornamented.
meaning
The gray mountain milkling is not an edible mushroom.
