Hedgehog mushroom

Found this little collection of funghi with a curious spikey underside. It turned out to be Hydnum repandum which is edible and meant to taste rather like Chanterelle. I guess looking at the bites out of some of them, there are some forest critters who already know this. However, I didn;t at the time, so I left them. But they are reputedly very good and hard to misidentify with their peculiar gills.
