I found these Split gill fungi (Schizophyllum commune) last November but had so many other things to share at that point that these didn’t make the cut.

I’d found the same species on another tree in this Cardiff Park once before but this fallen Oak and the huge colony of Split gill fungi growing on it were more than I’d ever seen before. It’s a fungus that always intrigues me, with its bland furry upper side that gives no hint of the stunning sculptural structure beneath.
