The butyriboletus subappendiculatus ( butyriboletus subappendiculatus , Syn. : Boletus subappendiculatus ), also Wrong appendage Boletus called, is a rare species of fungus from the family of Dickröhrlingsverwandten (Boletaceae). The species is a doppelganger of the appendage boletus ( B. appendiculatus ), which occurs predominantly in deciduous forests.

Macroscopic features
The hat, up to 8 cm wide, is initially hemispherical, later convex to flat-convex. It is rarely flat or slightly flattened. The smooth, fibrous or finely cracked surface of the hat is dry. Only old fruit bodies are sometimes slightly greasy. As a rule, the hat skin protrudes at the edge. The color spectrum ranges from brownish-orange, sun-tanned skin-colored to cinnamon brown, light brown to yellow-brown or cheerful clay-colored. Pressure points on the surface do not discolour. The stem can grow up to 13 by 5.5 cm and sometimes has a rooted stem base. Initially spherical to egg-shaped, the stem finally takes on a club-like or occasionally cylindrical shape, typical for thick tubers. Usually it is yellowish-white, pale yellow or pastel-yellow in color. The colors are seldom washed out partially or completely whitish or brownish. Sometimes the stem shows a reddish-white, pale yellow or brownish-orange zone in the middle or in the upper third. The entire surface or at least the upper half is covered with a fine-meshed, white or yellowish net of the same color. The color can even be rust-orange, orange or orange-red. As with the hat, the stem surface does not show any color change when pressed. The lemon-yellow, straw-colored or whitish flesh is sulfur-yellow, lemon-yellow or lemon-chrome-yellow under the cap skin, above the tubes and below the stem surface. At the base of the stem it is often dirty, salmon-colored to pale pink, wine-reddish or joyously clay-colored. In the cut it shows no blue on contact with air. The tubes on the underside of the hat are initially lemon yellow, then yellow with olive tones and do not change color when printed. The mouths of the tubes are first lemon yellow, then they show a yellow color with olive tones. Older fruit bodies sometimes have rust-stained pores, darken on pressure, but not blue. Both the smell and the taste are unspecific.
Microscopic features
The spores are 9.5–15 µm long and 3–4.5 µm wide. The ratio of length to width is between 2.4 and 4.3; the volume is 50 to 149 μm³. 4 spores mature on each of the clubbed, 30–39.5 × 7–10 μm large basidia . The top layer of the hat is a trichoderm composed of intertwined, septate and sometimes branched hyphae . The fungal threads are yellowish in color and finely encrusted on the outside. The mostly cylindrical end cells have rounded tips.
Species delimitation
The “real” tubular boletus ( B. appendiculatus ) can look very similar . The heat-loving fungus is, however, in deciduous forests home with beech, oak and hornbeam on limestone soil. The coniferous forest appendage tubule can be demarcated microscopically by the longer and narrower spores.
ecology
The coniferous forest appendage tubule is a type of higher-lying coniferous forest with spruce, pine and larch on acidic soil over primary rock (e.g. gneiss, granite) or at least superficially acidified soil. The fungus prefers heat-favored locations, such as those found in open high forests and along roadsides, and rises to an altitude of 1,700 m above sea level. NN on. It is a mycorrhizal partner of the spruce and grows from early July to mid-September.
distribution
The finds from Germany are concentrated in the south of Baden-Württemberg and Bavaria: the Black Forest, the Alps and the Bavarian Forest. Apart from evidence in Hesse, the species is missing in the rest of the republic. In Europe, the coniferous appendage tubule occurs in France, Italy, Norway, Austria, Poland, Slovakia, Slovenia, Switzerland, Spain, the Czech Republic and the United Kingdom. Finds from Bulgaria, Greece, Montenegro and Serbia are known on the Balkan Peninsula. The only evidence in Asia comes from Anatolia in Turkey. The Dickröhrling has not yet been found in the European successor states of the Soviet Union, but is probably to be expected there.
meaning
Like its close relative, the coniferous forest appendage tubule is considered edible, but it is also protected in Germany under the Federal Species Protection Ordinance and may not be collected.
