The photos below are from fungal growth in a walk in cooler. I wanted to determine if the
Foldscope could be used for field identification of a fungal organism. All photos except the picture in the cold room were taken with a Samsung Galaxy S-5 smart phone camera. Room florescent lights were used to back light the Foldscope image.

Conclusion: The $1 Foldscope microscope gives me enough information to field identify
Cladosporium spp. After the shot is taken with the camera it can be viewed and enlarged on the camera photo viewer. The image will not be as sharp as the Photoshop enhanced image or that produced by a Nikon microscope but it provides enough information to make the identification.
