L Paajanen, H Viitanen
A summary of the causes and sources of fungal damages was made on the basis of decay samples and sample information sent to the Forest Products Laboratory of the Technical Research Centre of Finland (VTT) between 1978 and 1988. About 50-130 decay cases in wood structures were studied annually. In almost 50% of all fungusdamage cases the cause was Serpula lacrymans. The proportion of Coniophora puteana is also high and the occurrence of Antrodia and Poria species is general. The most generally damaged structures were floors. According to sample information water pipe leakages often caused the damage.
