Jovan StosicBoletus pinophilus, commonly known as the pine bolete or pinewood king bolete, is a basidiomycete fungus of the genus Boletus found throughout Europe. For many years, Boletus pinophilus was considered a subspecies or form of the porcini mushroom B. edulis. In 2008, B. pinophilus in western North America were reclassified as a new species, Boletus rex-veris. Boletus pinophilus is edible, and may be preserved and cooked.
The fungus grows predominantly in coniferous forests, forming symbiotic ectomycorrhizal associations with living trees by enveloping the tree’s underground roots with sheaths of fungal tissue. The fungus produces spore-bearing fruit bodies above ground in summer and autumn. The large, edible fruiting bodies known as mushrooms appear under pine trees, generally in summer and autumn. It has a matte brown to maroon-coloured cap and its stem is often large and swollen, and the overall colour may have an orange-red tinge. As with other boletes, the size of the fruiting body is variable.
