Large field-of-view XFM ion maps of ion distribution in undecayed wood blocks (a–f) and wood blocks exposed to the model brown rot fungus Serpula lacrymans for 14 days in a soil block test (g–l). Two blocks were imaged for each treatment. The longitudinal wood axis was oriented vertically and the bottoms of the exposed blocks were in contact with the feeder strip during the soil block test. For a given ion, the intensities were scaled the same between blocks. Between ions, intensities were scaled to optimize visualization of ion spatial distribution.
