Is it common for mushrooms to fluoresce?
Lots of them will have some minor fluorescence, but some exhibit in a much greater/uniform form:
I know a common one that carries this similar type of yellow/green fluorescence are sulphur tuft mushrooms, I believe it is to do with the toxic alkaloids which they contain (but I could be wrong)
