It is an edible pored mushroom found in European and North American coniferous forests, growing in association with several species of pine of the subgenus Strobus.

It is ivory white in colour and very slimy, growing to 10 cm in diameter.

The stem is slender, ringless and ivory white with grey granular dots or blotches near the top.

[1] Suillus placidus is found in Asia, Europe and North America occurring exclusively alongside species of five-needled pine of the subgenus Strobus.

[4][5] In north-eastern North America, its range coincides with that of the native eastern white pine (P. strobus).
