Description

Cap: 5-20 (30) cm in diameter; convex when young, then flattening, depressed, finally becoming funnel-shaped, its margin infolded for a long time; whitish, cream-colored, often pinkish spotted; surface slightly sticky when wet, often soil and leaf debris sticks to it, slightly powdery-felty towards the margin, sometimes weakly zoned.

Gills: Slightly decurrent, densely standing, thin; whitish, later flesh-pinkish.

Stem: 2-5 cm long, 1-4 cm thick; cylindrical, tapering downwards; white, often with pinkish spots.

Flesh: Hard, snapping brittle, thick; white, exudes white milky juice on injury; odorless, burning peppery taste.

Spore: Pale ivory, sometimes with a pale salmon-pink tinge; 6.5-8 x 5.5-6.5μm; elliptical, decorated with small tiny warts.

Occurrence: From July to October, under poplar trees, especially in sandy poplar groves, often growing in masses, common species.

Edibility: Not edible.

Confusion: Similar to the not edible fleecy milkcap, the conditionally edible peppery milkcap, and the edible milk white russula.

Note: The genus name Lactarius means - milk-producing (lactating), the prefix Lacto- is used in connection with milk. - It refers to the fact that the mushroom, or when its gills are injured, exudes a milky juice. pubescens is a Latin word meaning hairy, downy, referring to the fine velvety, downy surface of the cap.

Species description: In 1815, the Swedish mycologist Elias Magnus Fries described it and gave it the binomial scientific name Agaricus pubescens. Also Fries, in 1838, transferred it to the Lactaruis genus, its new name became Lactarius blennius, which is still the generally accepted scientific name.
