The long-term storage of chips in the form of piles visibly decreases the quality of this material. The aim of the research was to identify the colonization by fungi of forest chips intended for energy purposes and the growth of fungi, as well as the changes they can cause in wood during the storage of chips. The first sample for biological tests was taken when a test pile was being raised on the premises of a power plant (the initial state) and successive samples were taken from the inside of the pile after 30, 60 and 120 days of storage. The surfaces of the samples were observed using a stereoscopic microscope. Wood inocula, taken from the inside of the samples, were placed on a sterile culture medium, incubated for 10 days, and then observed under a microscope. Numerous filamentous fungi, responsible for the soft rot of wood, were isolated from the samples taken when the pile was raised and after 30 and 60 days of storage; however, no traces of decay in these chips were observed under the microscope. For the first time, fungi belonging to the Basidiomycetes class were observed on chips taken from the pile after 120 days. Hence, it is only after 120 days that some of the changes in chip quality, signalised by a decrease in mass, may be connected with the growth of Basidiomycetes.
