This sample is from the dust of my vacuum cleaner and the fungi I wanted to examine is the one in the red square. On the top side (right image) it appears to be a dark green in the center while black around the edges. Additionally it appears to have a rough/fuzzy texture (I would describe it similar to maybe asphalt). On the bottom side(left) the color is a deep brownish black. If I was to hazard I guess, I would say this could be Cladosporium Herbarum, as the coloration is quite similar, however, the growth pattern of Cladosporium (multiple colonies) is different from what we see here.
