Tak tahle podivnost je taky houba. Jak jsem zjistil je to dost agresivní "dřevomorný" druh který ničí řadu listnatých stromů a dokonce se v Kanadě prodává k nakažení a likvidaci "nežádoucích" stromů v lese. To by mě tedy nenapadlo, ale evidentně to funguje aniž by to zničilo celý les.
So this weirdness is a fungus. As I found out, it is a fairly aggressive "woody" species that destroys many broad-leaved trees and is even sold in Canada to infect and destroy "unwanted" trees in the forest. So I wouldn't have thought of that, but obviously it works without destroying the whole forest.
