What is this big bubble in my mushroom?

[ragnarokreviews]

Any theories on this? This fuzzy mushroom nem has been fine for like 2 years and then today it just randomly grew this bubble that looks like a Xenomorph, implanted itself inside. I have 5 of these and I’ve never seen this happen and it’s only happening to this one?

I moved it a few inches away from the sunset nem, my only guess is it got stung?

Bump.

I'd say your nem stung it
