One hundred and seventeen clades of euagarics.
This study provides a first broad systematic treatment of the euagarics as they have recently emerged in phylogenetic systematics and recognizes eight major groups of homobasidiomycetes that cut across traditional lines of classification, in agreement with other recent phylogenetic studies. Expand
Comparison of ectomycorrhizal-basidiomycete communities in red spruce versus northern hardwood forests of West Virginia
Fungal species composition, spatial frequency, and sporocarp density in the two forest types differed as would be expected in light of the symbiotic nature of the fungi and trees considered. Expand
Does Rhododendron maximum L. (Ericaceae) Reduce the Availability of Resources Above and Belowground for Canopy Tree Seedlings?
The data indicate that competition for resources both above- and belowground is an important mechanism for inhibition of canopy tree recruitment by R. maximum, and water availability and the ability to accumulate soil nutrients are equally or more important than light to survival of canopy Tree seedlings in the presence of a subcanopy thicket.

New species of Amanita from Western Australia
Eleven new species of Amanita, Amanitaceae, are described from the southern Eucalyptus-dominated forests of Western Australia. One distinctive species is referred to subgenus Amanita, sectionExpand
Randomly amplified polymorphic DNA markers are superior to somatic incompatibility tests for discriminating genotypes in natural populations of the ectomycorrhizal fungus Suillus granulatus.
RAPD marker analysis is more reliable and provides higher resolution of genotype distribution in natural populations than does somatic incompatibility testing, of particular importance in populations of organisms such as ectomycorrhizal fungi in which the mating systems are incompletely known.

Intersterility Groups in the Pleurotus Ostreatus Complex From the Continental United States and Adjacent Canada
Mating compatibility studies using strains from 170 North American collections in the Pleurotus ostreatus complex reveal three intersterile species of oyster mushrooms in the United States and Cana...
The authors' primary objective was to determine if the Downy (Dendrocopos pubescens), Hairy, and Pileated (Dryocopus pileatus) woodpeckers, and the Common Flicker of the oak-hickory forests of southwestern Virginia, preferred to nest in trees infected by heart rots or whether they excavated nest cavities in trees with firm, undecayed wood.

Inhibition of seedling survival under Rhododendron maximum (Ericaceae): could allelopathy be a cause?
Litter can have an allelopathy effect on seed germination and root elongation of bioassay species as well as some ectomycorrhizal species, however, this allelopathic affect is not manifest in field sites and is not likely to be an important cause for the inhibition of seedling survival within thickets of R.m. sites.
