Earwig fungus

I saw what looked like a woolly caterpillar under a leaf of hogweed in Mice & Red today, but it turned out to be a dead earwig firmly stuck to the leaf blade by a fungus that had burst out of its body.

I have often seen fungus-infected hoverflies glued to grass blades, but this is the first time I have come across an earwig in this condition.

I have made some enquiries and hopefully will be able to identify it to species level in due course.
