Wood decay fungi species and their damage types at log depots in Western Black Sea region

Wood-destroying mushrooms harm wooden parts technically and financially. For the purpose of avoiding such loss, it is necessary to fight wood-destroying mushrooms. For the fight to be effective, it is vital to identify the type of the mushroom and the harm that it gives, and to take measures appropriate for the type. Thus, it is possible to fight against the mushrooms harming wood to some or full extent. This study intends to identify the types of mushrooms harming wood in log warehouses located in the Western Black Sea region and to find out the damage that the harmful types cause to the wooden parts having industrial importance. The study was carried out in Bartın, Bolu, Düzce, Karabük, Kastamonu and Zonguldak, the provinces located in the Western Black Sea region. 16 log warehouses in the Western Black Sea region were chosen for the study. The selection of the log warehouses was made regarding the annual production capacity and the ones with the highest capacity were selected. The wooden parts chosen for the study were the woods in logs and the seized products. The harmful types of mushrooms were taken using microscopic and macroscopic metod and the type was identified through a special kind of method. The pictures of the types of mushrooms were taken while they were still on the materials and they were kept in special boxes avoiding any intermingling or deterioration. The identification and evaluation of the types of the mushrooms were made by Mushrooms Application and Research Directorate, Konya Selçuk University. The actions of picking and studying the types of the mushrooms taken were carried out between February and October in 2016, and 8 field trips were made. With the help of the studies, 20 different families were detected in log warehouses in the Western Black Sea region. 33 different kinds and totally 48 different types belonging to the families were identified. Different types of mushrooms detected were 34 in Düzce, 13 in Bolu, 6 in Zonguldak, 14 in Bartın, 6 in Karabük and 12 in Kastamonu. It was found out that there were different types of mushrooms in Düzce. The study revealed that 55 percent of the types of mushrooms in the region were the ones belonging to Polyoraceae family. Moreover, it was discovered that Cerioporus meridionalis, Trametes hirsuta, Trametes versicolor, Schizophyllum commune and Stereum hirsutum were available nearly in each province. Trametes hirsuta and Trametes versicolor types were found in all types of wood. It was also seen that the type of wood having the most type varieties was beech tree. Antrodia crassa andAmyloporia sinuosathey were discovered to be a new record for Turkey.As a result of the field studies and the natural durability tests performed in the laboratory, the greatest weight loss was observed in beech wood. Trametes versicolor was determined to be the fungus species causing the highest amount of weight loss. Statistically significant differences in weight loss were found between the 3-month and the 4-month fungal exposure periods. Keywords: Log storages, Western Black Sea region, Wood destrying fungi.
