yeah, colony on this plate is likely aspergillus spp.
Why would it be mold if the OP was culturing bakers yeast?
The culture was contaminated with fungal spores.
look at the 1:10 plate. there's colonies that isn't yeast there. luckily, it got diluted out, or, maybe that plating was a bit more careless than the others.
i didnt mean to imply that all of the colonies aren't yeast.
