The Common vuilleminia ( Vuilleminia come dens ) is a very common fungus from the family of the splendor beef mushroom relatives (Corticiaceae).
features
Macroscopically
The fruiting bodies grow resupinate on the colonized substrate. The fungus can cover it up to over a meter and become up to a few millimeters thick. It has a yellow-brown to purple-flesh-colored tone. The surface is smooth and waxy. In damp weather, the fungus swells and takes on a gelatinous consistency.
Microscopic
The spores are allantoid (sausage-shaped), smooth, and measure 17-22 (25) × (4.5) 5.5-7 micrometers, mean 20-22 × 6-6.5 micrometers. They are granulated inside and weakly amyloid . The basidia are very long with up to 100 micrometers and have buckles. Cystidia are absent.
Species delimitation
The common bark sprinkler is also difficult to differentiate microscopically from other species of the bark sprinkler genus . A determination based only on the substrate is fraught with uncertainties in the genus. Most similar to the common bark sprinkler is the alder bark sprinkler ( Vuilleminia alni ). It differs through somewhat narrower and more curved spores, which are on average smaller (18–19 × 5–5.5 µm). In addition, the fruit bodies are more brick-red when fresh and the species predominantly populates alder and elm . The common bark sprinkler differs from other species in that it lacks cystids and allantoid spores.
ecology
The common bark sprinkler grows between the bark and the wood of the affected branches and twigs of deciduous trees. In the course of time, it loosens the bark. The colonized substrates come primarily from oak and red beech . The mushroom can be found all year round.
distribution
The common bark sprinkler and related species are common in North America, Europe, North Africa, Asia ( Asia Minor , Japan) and New Zealand. In Europe, the area extends from Great Britain, the Netherlands and France in the west to Poland and Hungary in the east and south to Spain and Italy and north to the Hebrides and Fennoscandinavia.
