Description

Quite a variable species with some specimens have a vivid orange cap and others with paler yellow caps, these colour changes from younger specimens to older ones and how dry the specimen is. The typical form is known as Suillus grevillei var grevillei and differs from var. badius by not having a chestnut or red cap. 

Smell

Not distinctive.

Season

Summer to late Autumn.

Habitat & Distribution

Exclusively with Larch (Larix), and common where these trees occur.

Edibility

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 

6-11 x 3-4 μm. Subfusiform to broadly elliptical.

Spore Print Colour

Ochre.

The red-brown form of the Larch Bolete (Suillus grevillei var. badius), is identical except for the much redder colour.


The Bovine Bolete (Suillus bovinus), is more of a washed out yellow/peach/orange colour and usually grows with pine.


The Weeping Bolete (Suillus granulatus), at the top of the stem is usually covered in cloudy droplets
