Mold colonies from a persimmon

A partially-eaten persimmon was safely allocated with the goal of letting it ripen further until it developed enough mold to collect for observation, which was approximately four nights total. Mold was collected from three areas of the persimmon with different mold-concentrations: an area completely covered with mold, an area with a medium concentration of mold, and an area with very little mold that appeared to have just formed. I believe that the mold did not grow uniformly as the area with the highest concentration of mold was the area that was exposed to my saliva, while the other areas were only exposed to the air when I cut the piece that I wanted as my sample. The multitude of branches are what I believe to be the mycelium of the mold. The mold did appear slightly more green than the mold in the image. The very dark areas of the mold on the image appeared to be very dark green through the Foldscope, and the lighter branches were a lighter green.

Image 1: Mold collected from the area of the persimmon with the most visible mold. The mold appeared to be dry white fuzz with green, powder-like mold on the fuzz – which is very commonly seen on moldy fruits and citruses.

Image 2: Mold harvested from an area on the persimmon with a medium amount of mold concentration. The mold was not as densely packed as the mold from Image 1. This mold colony appeared to be more black in color and was wet, which could signify that the colony was not fully developed. More research is required to make that statement a concrete conclusion.

Image 3: Mold harvested from an area of the persimmon with minimal amount of mold. This mold colony appeared to be very recently formed and very new, hence why the mold appears to be much lighter.
