During the trip in Ramot Menashe forests and I encountered countless mushrooms of this kind as if they had decided to take over all the fallen branches and stumps in the forest.
You can find an elaboration about this particular type of tree fungus here
I do feel obligated to remind you that this type of mushroom is NOT edible.
Enjoy!
