Discovering some of the "missing" fungal diversity (the difference between the approximately 300,000 species of fungi described to date and the 1,500,000 which have been speculated to exist)
Carolinian Agaricomycetes: compiling and confirming the records of mushroom fungi from the Carolinian Zone, and adding new records by traditional collecting of fruiting bodies and metagenomics of DNA extracted from soil
Determining the functional significance of fungal diversity in litter decay and the soil ecosystem, including agriculture
- Effects of different disturbance regimes, including different agronomic treatments such as till and no-tillpractices, on fungal diversity and the effects of these changes on ecosystem function
