mold on the pumpkin
Molds growing on the upside-down cap of my jack o'lantern. If I had to guess I'd say:
the stuff that's staining the flesh red-pink is a species of Fusarium, and so is the white mycelium in the foreground.
the grey fuzz right in the center is a Rhizopus.
the other dark grey-green patches are a Cladosporium
and there are a few patches of bluish Pencillium
I didn't look at these under my microscope, so I can't say more.
