Buchwaldoboletus lignicola: The Ultimate Mushroom Guide
About The Buchwaldoboletus lignicola Mushroom
Buchwaldoboletus lignicola is a species of bolete fungus in the family Boletaceae native to Europe and North America. Found on wood, it is parasitic on the fungus Phaeolus schweinitzii. It has a convex yellow- to the rusty brown cap, yellow to yellow-brown pores and stipe, and a brown spore print. Its edibility is unknown.
DNA testing moved this mushroom from Boletus to a newly erected genus called “Buchwaldoboletus”.
Edibility is unknown. Do not put it on your pot.
Other names: Wood Bolete, Houtboleet (Netherlands), Žltavec Drevový (Slovakia), Hřib Dřevožijný (Czech Republic), Brauner Nadelholzröhrling (Austria), Бухвальдоболет Древесинный (Russian)
Buchwaldoboletus lignicola Identification
Ranging from 5 to 11cm in diameter when fully expanded, the cap of Buchwaldoboletus lignicola is beige or light brown or slightly reddish-brown, and the surface is dry and velvety. Young fruitbodies have inrolled margins and rounded and domed caps, but with age, they become broadly convex and often develop irregularly scalloped and wavy margins.
Tubes and Pores
The tubes, which are decurrent to the stem, are 3 - 12 mm long; they terminate in elongated-rounded pores that are lemon yellow to bright sulfur yellow, not changing color when cut or bruised.
Ranging from 3 to 8cm tall and 0.6 to 2.5cm in diameter, the cylindrical or slightly spindle-shaped stipe of the Wood Bolete is usually yellowish near the apex and slightly darker towards the base.
When cut, the flesh may blue slightly or it may not change color significantly.
Subfusiform, 6.5-9 x 3-3.5µm.
Odor and Taste
A faint odor of oranges; taste not distinctive.
Habitat & Ecological Role
Buchwaldoboletus lignicola has been recorded across Europe from the far northern subarctic regions south to Switzerland, and North America from Ontario and Quebec south to Pennsylvania. It is considered endangered in the Czech Republic.
It is only found where the fungus Phaeolus schweinitzii grows, and microscopic tests have revealed it is parasitic on that species. The two are found with coniferous trees such as Scots pine (Pinus sylvestris), eastern white pine (P. strobus) and European larch (Larix decidua), and less commonly deciduous trees such as wild cherry (Prunus avium).
Buchwaldoboletus lignicola Taxonomy & Etymology
Buchwaldoboletus lignicola was described in scientific literature by the German mycologist Franz Joseph Kallenbach (1893 - 1944) in 1928, at which time it was given the binomial scientific name Boletus lignicola. The currently-accepted scientific name Buchwaldoboletus lignicola dates from a 1969 publication by Czech mycologist Albert Pilát (1903 - 1974).
Synonyms of Buchwaldoboletus lignicola include Boletus lignicola Kallenb., Phlebopus lignicola (Kallenb.) J.W. Groves, and Pulveroboletus lignicola (Kallenb.) E.A. Dick & Snell.
The prefix Buchwaldo- literally means 'beech wood'; however, as this species feeds on dead conifer timber it seems hardly appropriate. The name is actually in honor of the Danish mycologist Niels Fabritius Buchwald (1898 - 1986), the extension -boletus coming from the Greek bolos, meaning 'lump of clay'. The specific epithet lignicolus means living on wood.
