A tower of fungi

I spotted this mass of fungi sprouting out from a tree trunk in the garden this morning. I suspect that it is one species of honey fungus which is endemic on the island and over the past few years I have seen it growing from the roots and trunks of a number of birch trees in and around the garden. I’m hoping that it doesn’t spread to the more “manicured” areas of the garden as it could create havoc.
