The honeycomb stem porling , honeycomb porling or honeycomb porling ( Neofavolus alveolaris , syn. Polyporus mori ) is a type of fungus from the family of stem porling relatives (Polyporaceae). The eponymous square and wide pores on the underside of the hat are typical. Above it is colored quite happily with orange-brownish tones. The non-agaric is an alluvial forest inhabitant and colonizes dead ash branches there. The fruiting bodies appear mainly in spring, with good weather also with a second focus in autumn.
features
The honeycomb-forming polyporus in hat and stem articulated fruiting bodies with a 2-8 cm wide hat. The hat is round to oval or kidney-shaped, with a slightly indented or pinned center. The top of the hat, which is covered with fine scales, is yellow to orange-reddish when young and fades with age, in shady locations the color can also be yellowish-white. The usually very short stem sits centrally to laterally and is whitish to cream colored. Typical of the species is the creamy white to yellowish underside with relatively large, honeycomb pores. The pores are elongated polygonally, about 1–5 mm long and 2–5 mm wide. The tubes measure up to 5 mm in length.
Species delimitation
The wide- hole stem porling differs from the honeycomb stem porling in that it has a slimmer habit with a long, thin stem and a gray-brown hat with a bristly edge.
The sclerotia stalk porling can look quite similar when young, but has significantly smaller pores.
Ecology and phenology
The honeycomb-polyporus is a saprobiontischer , white rot producing wood inhabitants. Its main substrate in Central Europe is Fraxinus (ash), alongside other hardwoods, Breitenbach and Kränzlin especially mention walnut . The species occurs mainly in ash-black alder forests, pedunculate oak-field elm floodplains, humid hornbeam-oak and ash-sycamore maple forests at lower altitudes. Overall, fresh to moist soils that are well supplied with nutrients are preferred. Outside of forests, the honeycomb stem porling grows in rows of trees along rivers and canals as well as in parks and gardens.
The fruiting bodies appear from the end of April to September, in warm locations even from March, whereby two fructification spurts (spring and August-September) are possible in warm, dry summers . In contrast to this information from Krieglsteiner, Breitenbach and Kränzlin point to the limited fructification period from April to May.
distribution
The species is common in temperate Asia, North America and Europe. In Europe, the heat-loving honeycomb stem porling is widespread in Mediterranean and southern temperate areas. The closed distribution area reaches its northern border in Baden-Württemberg and Bavaria, which continues via the Czech Republic, Slovakia and south from Poland to southern Russia. To the north of it, only individual finds are known in Germany. Krieglsteiner reports that the fungus has been becoming more common since the mid-1970s, which he attributes to increasing urbanization and the associated warming of the landscape.
meaning
The honeycomb stem porling is not an edible mushroom, as a wood destroyer it is not of forestry importance.
