System
In Central Europe, there is a second type, Daldinia vernicosa. This has gelatinized trama, slightly smaller spores and stalked fruiting bodies. Otherwise, the coal - ball fungus is well characterized by its zoning. There are more recently efforts to split the carbon - ball fungus in several ways.
