The Montane Blue Stalk Zärtling ( Entoloma sodale , Syn. : Leptonia brunnea, Leptonia lampropus ss Bresadola. Leptonia sodalis and Rhodophyllus sodalis ) is a European fungus art from the family of Rötlingsverwandten . The fungus belongs to the species-rich subgenus Leptonia and grows mainly in meadows and pastures with calcareous soils. The Rötling is on the Red List of Threatened Species in Germany and is considered "endangered" (Category 3).

Macroscopic features

The 0.5–3.5 cm wide hat is convex and more or less maintains this shape over time. He has a slightly depressed, bifurcated middle of the hat. In the center the surface is finely to coarsely structured, outwardly towards the edge of the hat with stringy fibers. The hat shows no or only weakly translucent grooves, but the lamellae can also be seen through the hat skin from the edge to the center of the hat. The color palette rich in young fruit bodies from umber to medium to gray-brown, often almost black in the center. With age, the colors fade and can also turn out much lighter: more yellow or ocher brown to pale brown. The hat does not change its colors when it dries, but it does get a silky sheen. The lamellae, which have grown to a rounded shape and are slightly distant, are initially creamy-whitish, then pale gray-pink and finally old-pink. The cutting edges are the same color as the lamellar surfaces. The 1–6 cm long and 10–45 mm thick stalk sometimes has a central furrow and becomes hollow with age. The stem surface is matt and, in young specimens, is very finely spun in stripes. Initially, the stems have a blue-gray color with a purple bezel or are pale bluish in color. In old age, gray colors predominate, with a more or less pronounced blue-green shade. The colors fade towards the base of the hat. Like many species of the subgenus Leptonia , the fruiting bodies have a white felted stem base. The trama shows a gray-white to bluish color. The meat smells either inconspicuous or slightly floury. The taste is also inconspicuous or very weakly fishy and tranquil.

Microscopic features

4 spores mature on each of the basidia . The spores have 5–7 (–8), rarely 9, distinct corners and measure 8.5–11.5 (–13) × 6.5–8 micrometers. The length to width ratio is 1.45. The lamellar edges are either sterile or heterogeneous. The often very broad cheilo cystidia are very variable in shape: club-shaped to almost round-jointed, sometimes also thick-necked, bottle-shaped and extended with 1 to 2 heads at the tip. The top layer of the hat is a cutis made of lying hyphae that merges into a trichoderm in the middle of the hat. The cylindrical end cells are barely clubbed and have a diameter of 7.5-20 (-25) micrometers. The pigment is intracellular. There are no buckles on the hyphae .

Species delimitation

There are a number of Rötlingen from the subgenus Leptonia that produce fruiting bodies with blue stem and brown hat colors. Certainly they can only be distinguished on the basis of their microscopic features.

Polished-handled affectionate

For example, the Polish-stemmed tenderloin ( Entoloma poliopus ) can look confusingly similar to the Montan bluestalk tenderloin. However, this has a more matt stem surface and slimmer, sometimes brown colored cheilocystids.

Ecology and phenology

The Montane Bluestalk Zärtling grows on mossy meadows, natural pastures and is also found on heaths and dunes. The species prefers calcareous soils and colonizes both dry and wet locations. The fungus is distributed vertically from montane to subalpine.

The fungus fructifies from August to October and appears as early as June in rainy periods.

distribution

The Montane Bluestalk Zärtling is widespread in Europe and extends to northern Italy in the south and France, the Netherlands and Scotland in the west. In Central Europe there is evidence from Germany, Poland, Austria, Switzerland, the Czech Republic and Hungary. In the north of the continent, the species occurs in Fennoscandinavia . In Germany, the species is known from the federal states of Bavaria, Baden-Württemberg, Rhineland-Palatinate, Saarland, Saxony and Mecklenburg-Western Pomerania.
