“…Their presence 1 yr later can be explained by both the supply of assimilable substances derived from the activities of the decay fungi and enzyme activities (production of pectinase, cellulase, hemicellulase, xylanase, laccase) and the ecophysiological characteristics (tolerance to toxic compounds in the wood, production of toxic metabolites and mycoparasitism) that many of them display (Domsch et al 1980, Varese et al 1996. They inhabit the phylloplane, rhizosphere and soil, and belong to the nondecay fungi.…”
