Hi all. I found a strange growth on a mushroom here in the Southeast United States. Google lens is confused and ultimately useless for identifying what this is. Has anyone we use seen something like this growing on a mushroom? Any idea what it is?

One thought would be a genetic abnormality, but it might also be some kind of parasitic mold or fungus. I'm just a hobbyist so I'd appreciate any expertise that could lead to an ID.
