I bought a punnett of mushrooms from my local greet grocer today, usually very reliable, but today in my box I found this mushroom (photo attached). It has a blue-y purple hue, about five cm long. I can't find a match for it online, and I probably won't eat it but I was curious to know what it is. It may be coincidental, but my fingers feel a little tingly for having handled it. Any ideas?
