Strobilomyces strobilaceus
Common Strubbelkopfröhrling ( Strobilomyces strobilaceus )
The common Strubbelkopfröhrling ( Strobilomyces strobilaceus, syn. S. floccopus ) is a species of fungus in the family Dickröhrlingsverwandten. It is native to Europe and North America and in Europe the only representative of its genus.
Young fruit bodies are edible. Due to the often bitter taste, it is not recommended as edible mushroom.

Features
Macroscopic characteristics
The 4-10 cm broad hat has a hemispherical young and later a curved shape with a fringed, curled edge. Striking are the very soft, dark gray to black, pyramidal or erect, scale-like structures on the otherwise gray brown to almost white hat surface. The hexagonal pores or openings of the tubes on the Hutunterseite have a dirty white or gray in color and brown on pressure. The largely cylindrical, towards the tip slightly stronger stem is up to 14 cm long and 2 cm thick at the. He is colored like the hat and has a fuzzy surface. The inside is filled and fibrous structures. The meat ( Trama ) thick, spongy, chewy in the stem, initially white and turns on contact with atmospheric oxygen only ( brownish ) pink, slate gray and then black.
Microscopic characteristics
The elliptical, dark brown to black spores measure 9-15 × 8-12 microns and are covered with a net-like pattern.
Artabgrenzung
The hat surface of the hawk fungus ( Sarcodon imbricatus ) looks similar in damp weather. Strobilomyces confusus has a smaller hat with small and stiff scales. Its spores have irregular strips that resemble a partial network. The hat of Strobilomyces dryophilus is colored a dull gray - pink to light brown and rosalichem produces spores with a complete network as a surface pattern.
Ecology
The Strubbelkopfröhrling is a mycorrhizal fungus, which is rarely associated in Central Europe, especially with the common beech, spruce forest with pine, oak or white pine. The species occurs in various types of beech forests such as orchids beech forests, Hair barley or grove Sims beech forests. In addition, beech and fir forests, oak-hornbeam and spruce - fir forests can be colonized, pure spruce forests are avoided. The fruiting bodies appear in Central Europe from summer to late autumn.
Dissemination
The Strubbelkopfröhrling can be found in North America, Mexico, North Africa, China and Japan. In Europe it is absent in the far north, in Germany he is with the exception of the northern plains scattered everywhere to be found.
System
The congregation was first described Strubbelkopfröhrling by the Italian naturalist Giovanni Antonio Scopoli 1770.
Some authors see the Strubbelkopfröhrlinge in the independent family " Strobilomycetaceae " that are close to the Dickröhrlingsverwandten ( Boletaceae ) is related. Marcel Bon counts the genus contrast to the Dickröhrlingsverwandten and assigns them to the subfamily " Strobilomycetoidae ".
