This was from an air sample on my kitchen window sill behind the sink, left open for an hour.
The fungi a bumpy center. It’s a dark green all the way to the edges and it showed up fast but took longer time to grow big, maybe a week and a bit. The bottom of the fungi is also a dark green almost black in center.
I think this fungi might be Cladosporium herbarum because there is no white ring around it on the edges, its all green from the top and bottom, and the bottom is much darker than the top which is seen in cladosporium.
