MACROMYCETES IDENTIFIED ON THE CONSTRUCTION WOOD OF HISTORICAL MONUMENTS FROM MOLDAVIA AND CAUSES OF THEIR DEVELOPMENT

This paper presents a series of observations made at the historical monuments in Moldavia region, where they could show some cases which causes the appearance of macromycetes on wood. We maintained as significant a number of 13 species of macromycetes which were reported with greater frequency on construction wood, but also were included and species which are considered important agents of deterioration for wood: Gloeophyllum sepiarium (Wulfen) P. Karst., Gloeophyllum abietinum (Bull.) P. Karst., Schizophyllum commune Fr., Trametes versicolor (L.) Lloyd, Coniophora puteana (Schumach.) P. Karst., Serpula lacrymans (Wulfen) J. Schr t. etc. In the presence of a source of infection, it was found in some cases favorable conditions to the development of the sporiferous bodies. The number of attacks of macromycetes on historical monuments in Moldavia and the rate of the degradations on wood depend on a number of factors which were presented according to their importance in the overall process of preserving the timber used in construction. There were identified areas where the resistance of wood has been changed due to the destructive action of physical factors (improper humidity, temperature etc.) and especially because of the installation on this type of organic material of a considerable number of bodies from the various groups.
