Mark record


Trees in two-45-year old stands of aspen were sampled for microorganisms in discolored and decayed wood. The main genera of fungi imperfect isolated were Phialophora, Libertella and Ascocoryne. The commonest decay organism was Corticium polygonium followed in decreasing order of frequency by Fomes igniarius, Phlebia strigoso-zonata and Pleurotus ostreatus. Trichocladium canadense was usually found in the wood near the stump as was Armillaria mellea. Bacteria and yeasts were common, especially in colored wood. From the location of the main organisms recorded, a succession of organisms is apparent. The presence of F. igniarius apparently is influenced by aspen clonal characteristics
