SUMMARY

Almost 1000 wood blocks, 8 cm3, of beech (Fagus sylvatica L.), colonized by the mycelial cord-forming basidiomycetes Hypholoma fasciculare (Huds. ex Fr.) Kummer., Phallus impudius (L.) Pers., Phanerochaete (Ph.) laevis (Fr.) Erikss & Ryv., Ph. Velutina (DC ex Pers.) Parmasto, Steccherimum fimbriatum (Pers. ex Fr.) Erikss. and Tricholomopsis platyphylla (Pers. ex Fr.) Sing, were placed at the soil-litter interface in five different woodland sites. All species except T. platyphylla grew out radially from the blocks to form a network of mycelial cords ramifying amongst the litter and upper soil horizons. Initial outgrowth was more strongly related to microclimatic factors than to availability of nutrient resources, and after 3 months significantly greater (P<S 0.05) mean radial extension had occurred from blocks implanted during spring than from those implanted in winter or mid-autumn, Systems of H. fasciculare and Ph. Velutina were always of significantly greater (P<0.05) radius than those of the ther species after 3 and 6 months.
