Description

A distinctive species, when fresh covered in a thick mucus like substance, this can quickly disappear if dry, leaving a shiny brown-purple cap. Large thick ring with dots just above the stem and growing with Pine (Pinus) should make this species relatively straight forward to identify. 

Smell

Not distinctive.

Season

Autumn.

Habitat & Distribution

With Pine (Pinus) where it can be common where these trees occur. 

Edibility

Edible, we do not like any of the Suillus family, there are far better species to target, but they are often eaten in Eastern Europe, where the slimy layer and top part of the cap are peeled off, the tubes removed and just the flesh of the cap which is very well cooked is used.

Confusion Species

Spores 

7-10 x 2.5-3.5 μm. Subfusiform to elongate elliptical.

Spore Print Colour

Ochre.

Suillus collinatus which lacks the ring on the stem and the stipe base and mycellial strands are pinkish. 


The red-brown capped form of the Larch Bolete (Suillus grevillei var. badius) does not have small dots above the ring on the stem and grows with Larch (Larix) not Pine (Pinus).
