We describe a method for the three-dimensional live imaging of filamentous fungi with light sheet-based fluorescence microscopy (LSFM). LSFM provides completely new opportunities to investigate the biology of fungal cells and other microorganisms with high spatial and temporal resolution. As an example, we study the established aging model Podospora anserina. The protocol explains the mounting of the live fungi for the light sheet imaging, the imaging procedure and illustrates basic image processing of data.
