The rust-red larch boletus ( Suillus tridentinus ) is a mushroom from the family of the smeared boletus relatives . It is mainly found on lime-rich soils and is strongly tied to larches , to which it owes its German name.
features
Macroscopic features
The hat of the rust-red larch tubule is about 5 to 15 centimeters wide and initially hemispherical, then later arched. The edge of the hat is rolled up on young mushrooms and later bent down; on young mushrooms it is also hung with remnants of the velum . The color of the hat ranges from cinnamon brown to orange-red. The hat skin is ingrown with fibers and is typically greasy in damp weather. The first yellowish, then orange-red tubes of the mushroom are elongated towards the stalk, grown and slightly sloping down, with a diameter of one millimeter. The pores are angular and orange to brown-orange (when the spores are ripe), they turn rusty red with age. The spore powder is from olive to cinnamon brown in color. The stem of the rust-red larch tubule is four to eleven centimeters long. It is cylindrical or bulbous in shape and not infrequently curved. The yellow or orange-red stem has a fine net markings on the tip. With young mushrooms there is often a white veil between the edge of the hat and the stem, which disappears over time. The rust-red larch bolet has a firm, lemon-yellow flesh that is brick-brown with age, especially in the stem area, which turns rust-brown on average after a few minutes. Both the smell and the taste are unobtrusive.
Microscopic features
The elliptical, smooth-walled, and yellow spores are 9 to 16 micrometers long and four to six micrometers wide.
Species delimitation
The rust-red larch tubule can be confused primarily with other edible smear tubers, but it does not resemble poisonous mushrooms. If you also pay attention to the typical location, there is no risk of confusion with other mushrooms.
ecology
The rust-red larch tubule forms a mycorrhiza only with larches . It also needs calcareous soils and is therefore often found in the limestone Alps , but rarely in the lowlands. The rust-red larch tubule can be found between July and October.
distribution
The distribution of the rust-red larch tubule covers all of Central Europe, preferably montane locations such as the Alps and their foothills. The distribution area extends from Norway and Scotland via Belgium , Germany and northwestern Italy to eastern Austria .
meaning
The rust-red larch tubule is edible, even if it has a poor taste.
pharmacology
An extract of the rust-red larch tube shows an inhibitory effect on thrombin in laboratory experiments .
