Larch Bolete - Suillus grevillei
Variously coloured pale yellow, daffodil yellow, bright chrome yellow or bright rusty yellow, the cap of the Larch Bolete is very viscid when wet and remain shiny even in dry weather. It is 4 to 12cm across at maturity, and expanding until almost flat (occasionally conical or with a marked raised central area, known as an umbo), the caps of large specimens of this conspicuous bolete are quite often somewhat wavy at the margin. A woolly white veil covers the pores of young specimens. At first lemon yellow, the angular pores take on a cinnamon tint as the fruiting body matures. When bruised, the pores turn rusty brown.
In grassland under Larch trees.
June to October in Britain.
Suillus grevillei is ectomycorrhizal with Larch.
Widespread and fairly frequent in Britain.
Status in Leicestershire and Rutland not known.
