The blue bark mushroom ( Terana caerulea , Syn . : Pulcherricium caeruleum ) is a fungus from the genus Terana . It is considered the only species of this genus in the world.

features

The blue bark fungus forms resupinate (adjacent to the substrate), membrane-like, waxy fruiting bodies of a striking, violet-blue to almost dark-blue color, which is caused by a terphenyl . The surface of the fruiting body is smooth to slightly warty, the hyphae structure is monomithic (consisting of only one type of hyphae). The spore powder is white. The fruit bodies, which grow together from several round spots to form coatings up to one meter long, are up to 5 mm thick and are usually found on the underside of the substrate.

ecology

The blue bark fungus is a saprobiont that occurs on rotting, dead standing or lying trunks, on hanging or lying branches, in piles of wood or on exposed roots in the early to late optimal phase. Preferred substrates are hardwoods such as ash , maple , hazelnut , willow , hornbeam and oak . The fruit bodies are perennial, young fruit bodies and growths occur in Central Europe mainly in March, less often in October. The species prefers warm, moist deciduous forests and rarely goes above 400 m in Germany.

distribution

The blue bark fungus is distributed almost worldwide in warmer regions, it was found in New Zealand, Asia, Africa, North America, the Canary Islands and Europe. The European distribution area includes southern Europe and the oceanic western Europe (Portugal, Spain, France, southwestern Great Britain). The Central European distribution area includes Switzerland, Austria and Luxembourg, the current eastern limit of distribution is on the Upper Rhine. An isolated occurrence exists in Norway. In the 19th century the species suffered a reduction in area and is now considered lost in Germany north of the 50th parallel, the Netherlands, Belgium and Scandinavia. In February 2019 there was a find in the Tierpark Arche Warder e. V. in Warder / Schleswig-Holstein.

meaning

The species is out of the question as an edible mushroom, it is insignificant in terms of forestry. The blue bark mushroom was chosen by the German Society for Mycology as the mushroom of the year 2009 and thus attracted increased attention for the species, as its spread is to be expected in the course of general warming.
