This fungi is from a sample of tree bark that I took from two different trees in my backyard. As one can probably tell, it has grown a bit out of control as there is white mycelia all throughout the petri dish, going to all corners and touching the top. Additionally, we see these dark brownish/black spots forming on top of these mycelium strains. I believe that this is most likely Rhizopus Stolonifer based on the macro morphology observed
