Boletus pinophilus
species of fungus
Boletus pinophilus, commonly known as the pine bolete or pinewood king bolete, is a basidiomycete fungus of the genus Boletus. Described by Italian naturalist Carlo Vittadini in 1835, B. pinophilus was for many years considered a subspecies or form of the porcini mushroom B. edulis before genetic studies confirmed its distinct status. In 2008, B. pinophilus in western North America were reclassified as a new species, B. rex-veris.
The fungus produces spore-bearing fruit bodies (i.e. mushrooms) above ground under pine trees in summer and autumn. It has a red-brown to maroon-coloured cap and a large and bulbous stipe, covered with coarse orange-red reticulation. As with other boletes, the size of the fruiting body is variable.
The fungus is found throughout Europe and western Asia. It grows predominantly in coniferous forests on sandy soil, forming ectomycorrhizal associations in symbiosis with living trees by enveloping the tree's underground roots with sheaths of fungal tissue. Host trees include various species of pine, the European silver fir and European spruce, as well as deciduous trees such as chestnut trees, oak and beech.
The public source identifies “Boletus pinophilus” as species of fungus. This brief keeps that definition visible, then builds a research path around Boletus, pinophilus and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Boletus pinophilus”, the useful work is to connect “species of fungus” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 16, 2026. The linked authority identifier is Q1415435. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1835 and 2008.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
