| Popis: | Acid deposition contributes to forest health concerns at high elevation sites in Great Smoky Mountains National Park (GSMNP). Bark samples were taken from living trees at three study sites: Abies fraseri and Picea rubens from high elevation sites near the Clingman's Dome area of Tennessee; Juniperus virginiana and Quercus alba at low elevation sites at GSMNP in the Cades Cove area and also at Pertle Springs (PS), Missouri. All trees were climbed using the doubled rope climbing method and sampled for bark at approximately 3 m increments up to 12 m. A total of 162 laboratory moist chamber cultures were prepared in Petri dishes using bark samples representing all tree species, then measured for pH, and examined for myxomycete plasmodia and fruiting bodies. Thirty-four myxomycete species were observed and identified from cultures of tree bark from GSMNP that included two new records, Physarum auriscalpium and a possible new species of Trichia. Thirty species represent new records for the state of Mis... |
