I Dunno If My Hardwood Floor Is Rotting?…what Do I Do About These Pinhead-sized Black Spot/clusters On Floor?
It looks like they’re surrounded by areas that have become discolored, almost like they’re perpetually wet, like the light wood floor is now a shade of damp brown color. This is kinda around the edges of the wood where they’re adjacent to the other hardwood plank.
I live in an apartment. Is this serious enough of an issue to call the manager/facilities staff to replace the hardwood floor, or at least take a look at it?
I hope it’s not fungal spores, and that I could become sick from it. It’s right near my dining room table.
Oh, and these black spotty spore-things appeared on the stalks of my potted bamboo plant a few months ago. So I threw it out. It was gross. I didn’t know what it was, but they had appeared.

Water can seep in from just about anywhere, especially when you are in an apartment.
It definitely sounds like you have a mold issue and the landlord is required by law to fix it.
Mold can be a serious health problem so don’t delay. Call the landlord ASAP. If they can’t get this repaired pretty quick, ask to be moved to a different apartment in the same complex. This is actually your best option since apartment complexes rarely do a great job cleaning this up.
The local health dept can come check the air quality both before and after the cleaning is done to help make sure they got everything. If you end up staying there, ask for a follow up air quality check in about 30 to 90 days just to make sure. By the time you see the mold, you have already been breathing it for quite some time.
