Suillus luteus can be found all over the northern hemisphere.

One study discovered the existence of Suillus luteus strains with varying tolerance of zinc.

Suillus luteus is an edible mushroom.

Suillus luteus is a basidiomycete fungus, and the type species of the genus Suillus.

Suillus luteus is often confused with Suillus granulatus, which is another common mushroom occurring in the same habitat.

Brownish specimens may be mistaken at a glance for Suillus luteus, but a quick look under the cap will see there are gills rather than pores.

During favorable seasons, one can find there edible mushrooms, like saffron milk cap (Lactarius deliciosus) and sticky bun (Suillus luteus).

These include such as Boletus scaber, now Leccinum scabrum, Tylopilus felleus, Chalciporus piperatus and Suillus luteus.

Other than that, Suillus luteus is unlikely to be confused with other mushrooms, especially if its preferred home under pine trees and the whitish partial veil are taken into consideration.

It is often found near Suillus luteus and Suillus brevipes, and is known to parasitize the mycelium of both those and the truffle-like Rhizopogon species.

The Suillus family, characterised by its slimy cap, is another prized mushroom, the Suillus luteus and Suillus granulatus being its most common varieties, and while abundant in some parts of Eurasia, is a rare occurrence in others.

Suillus luteus forms mycorrhizal associations with various species of pine, which include Pinus sylvestris, Pinus nigra, and Pinus peuce in Europe, and Pinus resinosa and Pinus strobus in North America.

In the division Basidiomycota, it occurs in several members of the fungal family Boletaceae, the edible mushrooms Cantharellus cibarius, Volvariella volvacea, Pleurotus sajor-caju, Laetiporus sulphureus, and Suillus luteus, in the milk mushroom Lactarius hatsudake, and the coral fungus Ramaria botrytis.
