The mold on this CMA plate is from a swab of my window sill. It is a translucent, thin and white mycelia with black dots in it. It appeared quite early on but has not changed in size in a while. I believe it is Sclerotium cepivorum and the tiny dots are the sclerotia. Interestingly, this is a plant pathogen and the side of the window sill where this swab was taken from is beside the shelf I keep all my plants on.
