Ghost fungus

A couple of nights ago, whilst warding off cabin fever due to illness, DS1 and I went for a walk lateish at night to experience a night with no lights and we happened upon these. Not to be confused with ghoul fungus, THEY live off decomposing flesh or rather the ammonia. Omphalotus nidiformis are not edible and they glow in the dark. Never thought I would see such a thing, that's where the makers of Avatar must have got the idea from.
