What You Should Know
Suillus plorans is an edible species of mushroom in the genus Suillus. The species was originally named Boletus Plorans by Léon Louis Rolland before transferred to Suillus by Otto Kuntze in 1898. Although known as a predominantly European fungus, the species was recorded in Mexico in 1982.
This is a mutualistic ectomycorrhizal mushroom-forming fungus that exchanges soil mineral nutrients for photosynthates from its host. The species associates with five-needle pine (Subgenus Strobus) hosts.
Suillus plorans Mushroom Identification
Up to 10 cm, at first hemispherical, then expanding to convex, dark ochraceous to light or dark brown, dry or viscid.
Cylindrical or slightly swollen at the base, more or less concolorous with the cap, but mostly paler, covered throughout with brownish granuls.
Yellowish to yellow, unchanging when exposed to air. Tubes dirty mustard-colored to rusty.
Small, rounded, mustard-colored.
Odor and Taste
Smell not distinctive. Taste not distinctive.
Spores: 9–11.5 × 4–5 μm.
Alpine coniferous forests, but also underplanted trees in parks and gardens, mycorrhizal with five-needle pines (Pinus cembra, P. sibirica, P. wallichiana).
In Europe known mostly from the high mountains, where the mycorrhizal trees are present. Not yet seen in the Balkans, but it might be well present there under Macedonian pine (Pinus mugo).
Might be probably confused with Suillus variegatus which has paler cap, stem without granular dots, and flesh that blues in the cap. In addition, it grows under a wider range of pines.
