Daedaleopsis confragosa

Rötender sheets tangled Ling ( Daedaleopsis confragosa )

Called The reddening leaves tangled Ling ( Daedaleopsis confragosa ), also reddening Tramete or Rough Tramete, a species of fungus in the family is Stielporlingsverwandten ( Polyporaceae ). It is widely distributed, often grows in riparian forests of different deciduous trees and produced in infested wood a white rot.

Features

Macroscopic characteristics

The fruiting bodies reach a width of between five and twelve centimeters and can four to eight inches protrude from the substrate. They are between one and three inches thick. The top is first tinted whitish gray, later it will turn wine - red to ocher and is easily zoned. The surface is slightly pitted or radialrunzelig, the growth layers are white.

The hymenophore on the bottom is grauweißlich colored to pale brownish wood. It may be per formed very differently after fruiting. The variation ranges from completely pored over porous labyrinthine to approximately lamellig ( var tricolor). However, the two extremes are less common than the typical heavily extended, labyrinthine expression. Under pressure it turns wine - reddish pink in fresh specimens. The openings in the fruit layer up to 15 millimeters deep. The flesh is pale brownish wood and has a corky - chewy consistency. The spore powder is white.

Microscopic characteristics

The spores measure 7-10 × 2-3 micrometers and are inamyloid. They are cylindrical in shape to allantoid ( slightly curved ).

Artabgrenzung

Characteristic of the reddening leaves tangled Ling is the reddening of the Hymenophors in pressure. The Buckeltramete ( Trametes gibbosa ) has a similarly shaped hymenophore. Their flesh is white, however, and not brownish. Similarity also has the oak random Ling ( Daedalea quercina ), which has a significantly coarser textured hymenophore and a stronger growth; besides, he is usually found on oaks.

Ecology

The reddening leaves tangled Ling preferably more or less nitrogenous silver willow and alder field elm riparian forests, where it grows mainly on willow and alder. But also in corresponding hardwood stands away from river courses, particularly shady places and pioneer crops with high humidity, the fungus is frequently encountered. There he settled with preference hazel. It also occurs along roadsides, where it mainly affects hornbeam, birch, and rowan.

The reddening leaves tangled Ling is a Saprobiont and settled standing and lying trunks and branches that are still on the tree or lying on the ground. These can be either just died or already rotten. Rarely is the fungus can also be found on stumps of various hardwoods. In infested substrate it produces a very intense white rot. In about half of all cases pastures are infested. In a large margin birch and alder follow.

The fruiting bodies are annual, but can be very long outlast the substrate and can therefore be found throughout the year. Spore formation begins in the fall, increases in winter and subsides in early summer. Only when daily average temperatures below minus three degrees Celsius with very low humidity of the process is briefly interrupted.

Dissemination

The reddening leaves tangled Ling is widely used in North America to Mexico, Europe and Asia, and in Australia and New Zealand. In the Holarctic he is submeridional found to temperat.

In Europe, the territory of Spain and Italy extends south to southern Fennoscandia and the Baltic states in the north. In southern Scandinavia it is rare. To the east, the spread to Belarus, Hungary and Ukraine ranges, isolated in the Caucasus and the Urals. Generally the type to have a center in subozeanischen area and lacking in strong oceanic regions such as Portugal and Ireland, and the Eastern Mediterranean in Greece and Albania, or is overlooked here.

In Germany, the fungus penetrates far into the valleys of the Alps. Significantly thinner the occurrence in continental regions and located in coniferous forest areas.

System

Often a variety tricolor is distinguished. This has a much stronger burgundy colored hat that is somewhat uniform tinted and average slightly smaller, and lamelliges, more silvery hymenophore. Another feature is the preference for warmer locations. So colonizes the tricolor var only substrates to the submontane level and there is already rare. However Krieglsteiner doubts the validity of this variety, since transitions of the form of the Hymenophors and the hat color can occur in all combinations even on the same substrate.
