The spiked fungus type is called a hydnum. I’ve just searched for ‘Jelly Hydnum’ and it brought up Pseudohydnum Gelatinosum (toothed jelly fungus, or false hedgehog fungus) which, if it was fully transparent, might have similarities but, it occurs on well-rotted coniferous wood – which I can find nowhere in my body!
Though these spiked gel tops that come off my skin are really tough, nothing at all like a mushroom, more like tough plastic.
I’ve found my letter from the Dermatologist which, when talking about the biopsies says, no findings of pathological organisms . . . some changes supporting spongiotic change, consistent with eczema.
