AH. Open air mold test. can anyone identify? (pic) - Indoor Air Quality (I.A.Q.) and Mold Forum - The Inspector's Journal

I recently purchased an older building and decided to do an open air mold test. The petri dish showed up like this after incubating for 72 hours. I'm pretty concerned. Can anyone identify what's in the air based on the growth pic?
