Ectomycorrhizal associations in jack pine stands in northeastern Alberta

摘要: Ectomycorrhizae of jack pine occurring in mature stands, on bare roadsides, and a recently burned area were compared. Fifty-six fungus associates identified from sporocarp collections. Species Elaphomyces, Suillus, Cortinarius, Cantharellus, hydnums almost exclusively limited to stands. Laccaria proxima, Rhizopogon rubescens. Scleroderma macrorhizon, Astraeus hygrometricus typically found disturbed sites. Visual observations direct isolations ectomycorrhizae further indicated that the symbionts differed between burn site – lichen woodlands. A majority all sites nondescript could not be by culturing. Unlike vascular plants, ectomycorrhizal very numerous without any single species or small group dominating root systems. Pure culture syntheses confirmed Tricholoma flavovirens, T. pessundatum, zelleri, Suillus S. albidipes, Cenococc...
