That agar looks severely contaminated. Definitely not a mold but the colonies looks similar to yeast plaques. It reminds me of Candida spp grown on agar, but since colony appearance and expansion can change dramatically in different agar formulations, it could be something else, maybe even Saccharomyces spp.? How does that smell? Smell can be useful indicator if you are trying to find out what that is.

One thing is for sure - since the colonies all look the same, your contamination issue is likely caused by a single microorganism.
