Why This Research is ImportantCertain fungi are pathogenic to trees and forest wildlife, causing losses in forest ecosystems and forest productivity. Under ordinary conditions, forests are well suited to survive and thrive, even when exposed to organisms that cause disease or to episodes of environmental stress. The introduction of invasive pathogens, for which native organisms have no inherent genetic resistance, can result in massive loss of productivity and devastation to forest ecosystems. Invasive species are often introduced from other countries or from other ecosystems within the US. A thorough study of pathways associated with the introduction of potentially invasive insects and pathogens is needed to prevent tree death and decline.
Fungi are also the main decomposers of wood and leaf litter – these fungi are termed “saprotrophs.” Decayed wood and leaves contribute to soil organic matter, and hence directly to soil carbon sequestration. Decay products also indirectly contribute to carbon sequestration through positive effects on soil fertility and forest productivity. In most forests, the impact of forest management on the populations and functions of these pathogenic and nutrient-cycling fungi is unknown. Accurate identification of the fungal species involved, their relationships, and their biological activity are required to understand and assess the impacts of forest management practices, invasive species, and global climate change on forest health and productivity.The fungi associated with urban forests also need to be characterized.This knowledge is beneficial to arborists who must perform hazard tree assessments.
Pseudogymnoascus destructans, the causal agent of White Nose Syndrome, has killed over 6 million bats in eastern North America since the disease was first observed in 2006. Bats are a critical component of the ecosystem, primarily because of their impact on insect populations. One possible mode of pathogen transmission is human-mediated movement among hibernacula (caves and mines) – e.g., on the shoes, clothes and equipment of tourists and the caving community. Efficient and inexpensive protocols are necessary for cave visitors to clean their clothing and equipment to prevent transmission of this devastating pathogen.

National Research Highlights
Arborists need tools to help identify patterns of wood decay as part of tree risk analysis and decisions on the proper care of urban and community trees. Forest Service scientists prepared a series of articles to introduce arborists to frequently encountered decay fungi and patterns of decay in common oak and riparian tree species.
Heterobasidion root rot is a significant pathogen in the red pine plantations of the midwestern U.S. Little is known about its distribution. Forest Service scientists developed a DNA molecular test for field personnel to use in diagnosing the disease.
The culture collection and herbarium maintained by the Center of Forest Mycology Research (CFMR) in Madison, Wisconsin is one of the largest fungal 'libraries' in the world. The collection specializes in fungi associated with wood and contains both living fungi and dried reference specimens, which are used by researchers world-wide in studying forest pathology, disturbance biology, fungal genetics, distribution of invasive species, and impact of climate change on forest ecosystems. The CFMR's web-enabled database, accessible at http://www.fpl.fs.fed.us/research/centers/mycology/culture-collection.shtml, has recently been enlarged and updated.
NRS scientists Daniel Lindner and Jessie Glaeser are collaborating with the USGS Wildlife Health Laboratory in Madison, WI, to characterize the distribution of G. destructans in cave sediment samples from bat hibernation sites in the eastern United States.
