Lactarius obscuratus (Lasch) Fr. syn. L. obnubilus (Lasch) Fr. Kleiner Milchling, Alder Milkcap. Fruit body remarkably small and delicate for a Lactarius. Cap 6–16mm across, at first flat and slightly convex, later with a shallow depression, often with a small, somewhat pointed, umbo, dull cinnamon tinged, especially in the darker centre, with dull olivaceous tints or the centre hazel, later becoming somewhat brighter coloured and losing the olive tinge, very thin fleshed, transluid and striate at the margin due to the gills showing through, surface smooth or practically so. Stem 17–21 x 3–4mm, coloured like the cap margin, but a somewhat redder brown especially towards the base, cylindrical or slightly swollen at the base. Gills adnate to slightly decurrent, yellowish dull cream, slightly to somewhat closely spaced, thin, fairly broad. Milk white, unchanging; taste mild. Spore print whitish (A). Spores elliptic, warts joined by a well-developed network of ridges, 6–7.7 x 5–6.2µ. Superficial layer of cap cellular. Habitat in bogs under alder. Season early summer to late autumn. Occasional.
