I found some mushrooms in the forest and I'd like to know what kind it is, for being able to tell how to protect the trees from it.
growing location: central Europe, forest
host plant: beech tree, alive
season: late Summer (Sept. 15th 2020)
The area where the mushrooms were found is a typical beech forest with unusually low water levels, as the last few summers have been drier and warmer than usual. I presume the trees suffer more from these mushrooms because the trees are weakened due to the hot weather and little rain.
Some of the mushrooms dry out while on the host tree.
Picture Taking Conditions
The closeup pictures were taken at home. This was after transporting the mushrooms and storing them in the fridge for 2 days. They got a bit squeezed during this procedure.
