Biodiversity of pyrenomycetes in the Great Smoky Mountains National Park (USA).

The Great Smoky Mountains National Park (GSMNP) is an International Biosphere Reserve that spans more than half a million acres (2200 km2) between the mountainous borders of eastern Tennessee and western North Carolina. It is the site of a current All Taxa Biodiversity Inventory. Until recently, few studies on ascomycetes have been conducted in the park. Pyrenomycetes were chosen for study since they represent one of the largest groups of fungi, but are also one of the most poorly known most likely due to their small size (usually <1mm diameter). As part of a NSF Biotic Surveys and Inventories grant, pyrenomycetes were collected from wood, soil, dung and herbaceous material throughout the park. A combination of traditional random sampling and structured plot sampling along 30m long transects was employed. Over 1800 collections were made during 76 collecting days representing 213 collecting events from 2004-2008. Of these, 1063 (59%) have been identified to species representing approximately 445 unique species, 325 (73%) new park records and at least twelve (3%) new species to science. Other products developed during this study such as databases, species accumulation curves, identification guides and interactive keys will be discussed.
