Found within a puff ball mushroom. (Lycoperdon) I noticed tiny holes and to my surprise this little (about 1cm) critter was inside. A few of the other puffballs also had holes, which I assume may have had more beetles.
I don’t know how to identify beetles and used the AI to get to genus. Any help great appreciated!
Growing on dead log (unsure of tree species, oak?) also colonized by turkey tail, purple toothed poly pore, and several other fungi
