Eek! I just got home from a two week business trip and the parquet floor in my room had buckled and turned into my own personal hollow mountain. I quickly found out that underneath said mountain is a lake of some kind. As I was taking in my apartment’s new scenery, I noticed a black dot on my baseboard. When I got closer I realized that it wasn’t a black dot per se rather a thousand reddish-brown arms with black tips. I have no idea if this is dangerous but I am now positively terrified that this new ecosystem will have some serious adverse effects.
Can anyone help me identify this mold/fungus? Is it a pest or a predator?
