I found some old bread in the pantry that had gotten moldy. Before I threw it out, I put the mold under my Foldscope!
I really like the way they do look like little paint brushes!
Also, if you want to see more about bread mold and the different structures you can identify with your Foldscope, please read the Foldscope Explores... Mold! blog.
