Andrew M. Minnis Daniel L. Lindner David S. Blehert Michelle L. Verant 2017 <p><i>Geomyces</i> and <i>Pseudogymnoascus</i> (<i>Fungi</i>, <i>Ascomycota</i>, <i>Leotiomycetes</i>, aff. <i>Thelebolales</i>) are closely related groups of globally occurring soil-associated fungi. Recently, these genera of fungi have received attention because a newly identified species, <i>Pseudogymnoascus</i> (initially classified as <i>Geomyces</i>) <i>destructans</i>, was discovered in association with significant and unusual mortality of hibernating bats in North America (Blehert et al. 2009; Gargas et al. 2009; Minnis and Linder 2013). This emergent disease called bat white-nose syndrome (WNS), has since caused drastic declines in populations of hibernating bats in the United States and Canada (Turner, Reeder, and Coleman 2011; Thogmartin et al. 2012) and threatens some species with regional extinction (Frick et al. 2010; Langwig et al. 2012; Thogmartin et al. 2013). As primary predators of insects and keystone species for cave ecosystems, the loss of bats due to WNS has important economic and ecological implications.</p> application/pdf en CRC Press Geomyces and Pseudogymnoascus: Emergence of a primary pathogen, the causative agent of bat white-nose syndrome chapter
