- Identification and biosystematics of polyporoid wood decay fungi.
- Development of new identification techniques for detection of the pathogen Heterobasidion annosum.
- Development of techniques that induce the formation of spalted wood to add value to lesser used hardwood species.
- Investigating species boundaries and evolutionary relationships in the white rot genus Trametes.
- The effect of climate change on the distribution of white-rot and brown-rot fungi.
Why This Research is ImportantWood decay fungi are extremely important in the forest. Some, like Heterobasidion annosum, are serious pathogens that kill trees, while others are saprotrophic, breaking down woody debris and returning carbon and nutrients to the soil. The identification of decay fungi is often difficult, especially among the polypores, which frequently do not have distinctive microscopic characteristics. Developing better tools for fungal identification will allow us to identify potentially invasive nonnative pathogens and assess the health of disturbed and nondisturbed forests through their fungal communities. The scientific development of techniques for the use of white rot fungi in the production of highly valued spalted wood will provide a market for lower valued hardwood species.

National Research Highlights
DNA Tool Detects White-Nose Syndrome Fungus in Bat Caves (2010)
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.
Detection of Heterbasidion Root Disease Using Genetic Fingerprinting (2013)
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.
Managing Wood Decay in the Urban Forest (2014)
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.
Web-enabled Database for Center for Forest Mycology Research Expanded (2010)
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.
