The spread of bat white-nose syndrome and the fungus (Geomyces destructans) that causes the disease. Since the winter of 2006-2007 (red), the disease (solid colors) as determined by histopathology analysis, and DNA of the fungal pathogen (striped colors) as identified by PCR analysis, have been detected across large expanses of eastern North America. Mass mortality has not yet been observed in the westernmost outlying area where presence of fungal DNA on a hibernating bat was first indicated by PCR during the winter of 2009-2010 (green striped area to far left).
