The chestnut stem porling or chestnut brown porling for short ( Picipes badius , syn. Polyporus badius , Royoporus badius ) is a type of mushroom from the family of stem porling relatives . The name refers to the color of the hat (lat. Badius = chestnut brown). Other names are black-red and sweet-smelling Stielporling . The fruiting bodies can be more than 20 cm wide. The whitish underside with the pores , which contrasts with the upper side, and the blackish stem base are also striking .

features

Spores of the chestnut stem porlet under the light microscope

The chestnut brown Porling forms individually to socially standing fruiting bodies with a hat and stem that are divided into hats and stems, with a 2–25 cm wide hat, which can sometimes be grown together in several. The hat is round (circular to kidney-shaped), chestnut brown in color (often a little lighter towards the edge), smooth, bald and shiny. The edge of the hat is wavy to fluttered, sharp and thin. The white underside is covered with very fine (5–8 m per mm) round to angular pores that run down the stem. The tube layer is 0.5–2 mm thick. The stem sits centrally to laterally, 1–5 cm long and 0.5–2 cm thick, velvety hairy and brown-black in color, the color of the stem is well demarcated from the white pores. The meat is tough and thin. The mushroom smells pleasantly sweet.

Species delimitation

The Löwengelbe Stielporling is lighter yellow-brown in color and has no shiny, greasy surface. The black-footed stem porling can look very similar, but differs through a felty, matt, often lighter hat, a longer, central stem with curvatures or appendages and a growth closer to the ground. Similar is the rare Picipes tubaeformis with a strongly funnel-shaped, light gray-brown hat when young and slightly wider pores that run down. The chestnut stem porling differs from all three species microscopically by its buckle-free hyphae .

Ecology and phenology

The chestnut-brown stem porling predominantly colonizes thicker branches and trunks lying on the ground.

The chestnut stem porling is a wood-dwelling, white rot- causing saprobiont that can colonize a wide range of hardwoods (in Central Europe red beech , willow , poplar , ash , alder ). The species prefers humid beech, beech-fir or hornbeam-oak forests, riparian forests, poplar plantations and willow bushes. The fruiting bodies appear on dead trunks, trunks or branches, sometimes very high, mostly at a considerable distance from the ground.

The fruiting bodies appear from spring to autumn, according to Krieglsteiner in two batches (late May / early June and late August to early October).

distribution

The chestnut stem porling was found in Asia (Caucasus, Central Asia, Iran, North India, east to Korea and Japan), North America (to Alaska and South Greenland) and Europe. In Europe, the species occurs from northern Spain, northern Italy and Croatia to the Hebrides, Denmark, Estonia and southern Sweden.

meaning

Edible when young and quite spicy, but quickly becomes tough. Economically insignificant.
