The hare bolete ( Gyroporus castaneus ), also hare pale stem or cinnamon stem , is a very rare, edible species of mushroom from the family of pale sprouts relatives .
features
The thick-fleshed hat measures 3–10 cm in diameter and has a sharp edge. It is hemispherical in the young fruiting body and gradually flattens out with age. It is pale to rusty brown and darkens with age. The stalk is similar in color, possibly lighter towards the tip. It is largely cylindrical, often bulbous in shape at the base. In the young stage it is full, later it is chambered with vertically layered cavities of different sizes. Both the hat and the stem tend to break open during dry periods or in old age. The tube layer has not grown on the stem and darkens slightly on pressure. The pores or tube mouths are small and white and get dirtier with age. The tubes are also whitish and discolored by the pale to straw-yellow spore powder . The meat is firm, fragile and mild in smell and taste; Cut surfaces do not change their color in air.
Species delimitation
The closest related cornflower boletus is usually an intense cornflower blue, is whitish, straw yellow to ocher-brown in color and has a more chambered stem.
ecology
The rabbit boletus is a mycorrhizal fungus that forms a symbiosis with various deciduous trees, especially oak species in Central Europe . The species occurs in Central Europe mainly in oak-hornbeam forests and various types of beech forests, less often in spruce forests with interspersed deciduous trees. The boletus always prefers fresh, loamy to sandy, mostly acidic soils, but also occurs on neutral subsoil. The fruiting bodies appear in Central Europe between the last week of June and the first week of October.
distribution
The fungus is occasionally found in Europe with the exception of the extreme north, Australia, Asia and eastern North America, very rarely in western North America. In Germany, the rabbit bolete is evenly distributed, but very rare.
In some countries (Russian Federation, Norway, Montenegro) it is on the Red Lists of Endangered Species .
meaning
The rabbit bolet is edible and usually highly regarded. It should taste pleasantly nutty when young. Marcel Bon lists him in his 1987 book "The Mushrooms and Toadstools of Britain and North Western Europe" as suspicious. It can be incompatible with some people. There is also a report of a poisonous species found in coastal regions of Portugal, the False Rabbit Earling ( Gyroporus ammophilus ).
Taxonomy and Etymology
The species was first described by the French mycologist Jean Baptiste François Pierre Bulliard . Formerly considered a member of the Paxillaceae family, it is now classified as one of the pale spur relatives (Gyroporaceae).
"Gyroporus" means "round-pored", "castaneus" refers to the chestnut-like color.
