This mold is probably from the compost bin that I took a sample of, but it has taken over the entire plate. The mycelia is white, with tiny black dots, and the black dots are quite elevated from the plate. I did not take a picture of the bottom because there are other molds growing over most of the bottom, so it’s easier to ID from just the top. This mold also grew incredibly fast, it took less than a week to take over the plate and the area above it. This looks exactly like Rhizopus stolonifer to me.
