is anyone able to identify what type of contamination on my agar plates

Hi all! I ran some tests on some leftover spores I was storing in the refrigerator. I tested them on malt extract agar. Clearly, some of these are contaminated. But I was just curious, is anyone able to identify what type of contamination? Not important, just my own curiosity. I’ll toss the contaminated spores. Thanks everyone! 😃
