Buchwaldoboletus lignicola is a rare bolete with specific characters: growth on the wood of Pinaceae previously colonized by another rare fungus Phaeolus schweinitzii. It is associated with P. schweinitzii as a mycoparasite or a saprotroph at the same substrate. It’s is reported from in 16 countries of Europe, Russia, Turkey, China and eastern North America. In most countries it’s considered as a rare or very rare species, in 7 countries (Bulgaria, Denmark, Germany, Netherlands, Norway, Czech, Turkey it was estimated as a threatened species (Vu-En). Rather strict range of ecological requirements of this species makes it necessary to provide its special protection at the global level.

Buchwaldoboletus lignicola is a widespread species known in Eurasia and North America. At the moment it’s found in many countries, but almost overall it’s considered as a rare of very rare species.
In spite of wide distribution of this species in the world, it is considered as a rare or a very rare species in most countries. Usually single or a few findings per country are registered in their databases. General trends of existence are not entirely clear, however the specific requirements of this species to the hosts make it vulnerable to successful surviving.
Population Trend: Uncertain
This is xylotrophic fungus with a complicative life strategy. Usually it grows on the rotten wood of Pinacea trees (Pinus sylvestris, P. pinaster, P.strobus , P. nigra, Larix decidua, Pseduotsuga menziesii, Picea abies) previously colonized by another rare fungus, Phaeolus
schweinitzii (Fr.) Pat., a brown-rot fungus, which leads to the death of the host plant and then continuing to grow on the stump as saprotroph (Kuthan & Sedivy 1971). Sometimes it was also found just to be saprotrophic whithout any neghbourhood of other fungi. The species is known mostly from warm southern or temperate regions, but also a few records are from the northern regions with a mild oceanic climate (Funga Nordica, 2012).
The main threat is deforestation of coniferous forests including cleaning from the old stumps. Also grassroot fires can lead to destroying of habitat and destruction of hosts.
Since it’s globally widespread species and in some countries (i.e. USA) is not so rare, at the moment it doesn’t need special global protection. But in most European countries as well as in Russia it is a really rare species which existence is depending from the other rare fungus Phaeolus schweinitzii, therefore it can be assessed as threatened on the European or national levels.
Its edibility is unknown.
