The coal ball mushroom ( Daldinia concentrica ) is a wood-dwelling fungus from the family of the wooden club relatives .
features
The fruiting bodies are spherical to bulbous and are 2 to 5 cm in size. At first they are gray-brown and superficially as if they are dusted by the conidiospores and then become red-brown and finally black. The surface is finely humped in this last stage, since the perithecia are located here. The interior of the stroma is woody-charcoal and zoned concentrically, which explains the name. The spore powder is black with elliptical to bean-shaped spores that have a fissure. They are smooth and 13–16 × 7–9 μm in size.
ecology
The coal ball mushroom is a saprobiontic inhabitant of dead, barked branches and trunks of hardwood such as B. beech , oak , alder and birch . It is found in the conidia form all year round, especially in riparian forests and alder swamps with suitable substrates, but it is quite rare. In autumn it is spore-ripe.
Food value
The coal ball mushroom is inedible.
Systematics
In Central Europe there is a second species, Daldinia vernicosa . This has gelatinized trama, slightly smaller spores and stalked fruiting bodies. Otherwise the coal ball mushroom is well characterized by its zoning. There have recently been efforts to split the coal ball mushroom into several types.
