Slippery Jack - Suillus luteus
When wet the caps of this species are slimy; in hot sunny weather they dry to a smooth semi-matt finish. Cap usually a rich purple brown but becoming paler as it ages. The cap has lemon yellow pores, covered initially by a veil membrane which peels away to leave an irregular ring on the stem and occasionally with remnants around the cap margin. The veil is creamy-white when young but soon develops a deep lilac or violet colour.
Associates with Scots Pine and found in pine litter but also in grassland near pine trees.
August to November in Britain.
Widespread and fairly frequent in Britain.
Only recorded occasionally due to the specific habitat requirements.
