Whilst at Holme Dunes in Norfolk at the weekend one unidentified fungus in particular has proved to be tricky to even get to genus, despite going through a number of different fungus books. It looked and had the consistency of a jelly fungus, but had gills/gill-like folds. It was growing on a pine stump, which seems to rule out quite a few species. There were three, but they weren't overlapping. The overall habitat was the edge of some pines in a mature dune system.
