The cap is chestnut to dark reddish-brown, convex then expanded, sometimes depressed; its margin is smooth, inrolled for a long time. The cap surface is smooth, rather viscid, especially in damp weather, shiny when dry.

The stem is full, cylindrical, two-coloured: white at the apex, reddish brown below, with a circle, often viscid, acting as a membranous ring (in the youth) or ring zone, clearly marking the separation between the two colours of the stem.

The flesh is white, sometimes a bit reddish, unchanging; its taste is bitter; the odour is mealy in fresh specimens, or of watermelon; its texture is fibrous.

The gills are white then dotted with rusty-brown with age, emarginate, crowded . The spore print is white. This species is mycorrhizal. It grows on the ground, in coniferous woods, on a rather calcareous soil, mostly with scots pines.

The fruiting period takes place from September to November.
Dimensions: width of cap approximately 11 cm (between 5 and 15 cm)
  height of stem approximately 8 cm (between 3 and 10 cm)
  thickness of stem (at largest section) approximately 20 mm (between 10 and 30 mm)

Distinctive features : reddish-brown cap, slightly viscid to shiny; stem with ring zone clearly separating the white top of the stem from the reddish-brown part below; flesh with bitter taste; mealy odour when fresh; white gills, later spotted with reddish-brown dots; with Scots pines on calcareous soil
