Slimy-capped bolete with a spongy pore surface. Multiple species in Colorado. Edible but the slimy cap skin should be peeled before cooking. Common and abundant — a good beginner mushroom.
Habitat
Pine and spruce forests. Strongly mycorrhizal — different Suillus species associate with specific tree species. Very common after summer rains.
