Digdug, glad you found that mold. Get away from it as soon as you can. After the flood here. We had every color mold you could think off. We were told the black mold with the white coming off of it was the worse. Had to wear the painters masks to not breathe it in. Alot of people including me got sick from it all. We got this cough, they nicknamed the Katrina cough, and aching feelings in our joints. If you have that let your doc know. We were givien some kind of medicine to take for about a month. Alot of people still have the cough cause its still in the air down here. The thing is you cant smell it.

Good luck with the landlord. If i was you i'd demand my deposit and all past rental payments back. Plus a visit to the doc to make sure it hasnt gotten into your lungs.

Alot of cleanup to get rid of that. There gonna have to tear out a good portion of that wall if not the whole thing. That crap spreads like wildfire.

hugs
