Small beams of beech wood were subjected to decay by wood roting fungi for two, four, six, eight, ten and twelve weeks. Seven different wood roting fungi were used, isolated from a beech forest of the mountain Ossa. Physical properties of the decayed wood, including wet volume, moisture content, percent weight-loss, hardness and specific gravity were studied during the above mentioned periods of time. Of the seven fungi used, Fomes fomentarius and Coriolus hitsutus had the biggest effect on percent weight-loss, followed by C. versicolor and Lenzites betulina. The fungus Stereum hirsutum had even less effect on the percent weight-loss, while the effect of Schizophyllum commune and Hypoxylon fragiforme was insignificant. Proportionally similar with the percent weight-loss was the effect on the hardness reduction of the above fungi during the decay periods, but hardness was a more sensitive measure of early decay than percent weight-loss. The moisture content was affected by decay. In general, the moisture content increase with advancing decay for all the fungi except H. fragiforme but the rate at which it increased was different for every fungus. The wet volume of the tested beams was not changed during the decay periods of all the fungi. Finally, the reduction of the specific gravity followed a similar way with the percent weight-loss.
