Abstract The moist chamber culture technique was used to investigate the assemblages of myxomycetes (plasmodial slime moulds or myxogastrids) associated with the microhabitats represented by the bark surface of living black spruce (Picea mariana) trees and forest floor leaf litter in the Caribou–Poker Creek Research Watershed located approximately 50 km north of the city of Fairbanks. This study was carried out in the context of a larger project (Frostfire) that involved an experimental burn of a major portion of this watershed. Our study sites consisted of examples of the two major forest types (black spruce and birch–alder–quaking aspen) found within the watershed. Black spruce trees were sampled at three study sites (two burned sites and one control site), whereas samples of litter were obtained from four study sites (two control and two burned). The acidic bark of black spruce was found to
