Previously thought to exist in North America, that species has now been confirmed to be the rediscovered Suillus weaverae.

[6] It was given its current name by French naturalist Henri François Anne de Roussel when he transferred it to Suillus in 1796.

[10] The stem is pale yellow, of uniform thickness, with tiny brownish granules at the apex, and about 4–8 tall, 1–2 cm wide.

[11] Also similar is Suillus brevipes, which has a short stipe in relation to the cap, and which does not ooze droplets from the pore surface.

It has been found that Suillus granulatus can extract trace elements (titanium, calcium, potassium, magnesium and lead) from wood ash and apatite.

The fruit bodies—low in fat, high in fiber and carbohydrates, and a source of nutraceutical compounds—can be considered a functional food.
