    Opis:
    The development of Fomitopsis officinalis mycelium depending on the composition and pH of the medium and incubation temperature was examined in the experiment. The potential of mycelium growth on wheat grain and larch sawdust, as well as the decay rate of larch sapwood and heartwood samples were also analysed.

    Opis:
    There are over 100 thousand old trees protected as nature monuments in Poland. Their health condition in many cases is not satisfying and the new methods of their conservancy against pathogenic, wood decaying fungi are necessary to be prepared. In this paper the evaluation of practical usability of some phenolic compounds naturally existing in wood is described. Natural chemical substances as eugenol, isoeugenol, resorcinol, pyrogallol and 2−furaldehyde (furanone) seem to be very useful in this matter. Artificially applied directly into the stem of living tree by hydrostatic injection, they are able to protect it from the inside as well as commonly used synthetic fungicides, being also less dangerous for the natural environment.

    Opis:
    Black cherry is an important invasive species in forest ecosystems in Poland. It developed mainly in Scots pine stands. The aim of the study was to identify microscopic fungi colonies inhabiting black cherry stumps. In the spring of 2017, wood samples were collected from stumps created after cutting in each subsequent month of 2016 in the Podanin Forest District (19°28'00'E, 52°04'00'N). Stumps up to 5 cm and more than 5 cm in diameter were selected for the study. In total, 72 discs from the first stage of the decomposition of wood were collected. The discs were drilled to obtain fine sawdust for further analysis. The trials were divided into four periods. DNA isolation was performed using the Plant Genomic DNA purification kit (ThermoScientific). The ITS1/2 rDNA region was used for species identification. The analysis was carried out using specific primers. The obtained product was purified and sequenced using the Illumina SBS technology. The resulting sequence was compared using the BLAST algorithm with reference sequences from the NCBI database. The communities of fungi inhabiting the black cherry stumps differed from each other. The highest number of taxa was identified in samples from stumps over 5 cm sheared in autumn and winter, while the lowest in stumps up to 5 cm sheared in spring and winter. Fungi belonging to the Ascomycota and Basidiomycota, Blastocladiomycota, Glomeromycota, Zygomycota and non−cultivable fungi and organisms belonging to other kingdoms were identified. Saprophytes from Menispora sp. dominated on the analysed stumps. The collection of fungi of larger stumps was more diverse and more numerous than on stumps with a smaller diameter. A greater diversity of taxa was distinguished by the stumps of tree fallen in the growing season. The majority of the analyzed samples were dominated by Ascomycota. Basidiomycota clusters dominated in the winter. The predominant share of saprotrophs shows the distribution of stumps. The most desirable effect of the research would be the indication of naturally occurring saprotroph, whose operation would reduce the black cherry’s yield strength. The applied method of sequencing based on the Illumina System was effective to determine the composition of the fungal population.

    Opis:
    The paper describes the results of investigation on the range of trophic abilities and preferences of fungi causing the wood decay of the brown rot pattern. Fomitopsis pinicola, Laetiporus sulphureus, Piptoporus betulinus and Serpula lacrymans fungi were tested. Wooden samples made from wood of 25 different, both European and exotic, tree species were used. They were put on mycelium of every tested fungus. After 30, 60 and 90 days of exposition samples were weighted and the loss of their mass was calculated to compare the differences of wood destroying abilities between examined tree species. The results indicated that the range of trophic abilities in ex situ conditions of tested fungi species was much wider than in nature. All examined fungi were able to decay the wood of more tree species and their trophic preferences occurred to be different as well.

    Opis:
    Paper presents results of laboratory experiments on the usability of selected phenolic compounds naturally existing in wood for artificial wood protection against wood decay caused by fungi. Some of these substances are believed to work as inhibitors of mycelium’s growths and prevent wood against biological destruction. Six different phenolic compounds were tested individually or mixed together. Lime wood samples were artificially saturated by their water solutions using vacuum methods. Then they were put on the mycelium of Laetiporus sulphureus and Trametes versicolor. The samples were taken out after 30, 60 and 90 days. The loss of their weight was compared with control samples saturated only by water. The differences between these results allowed to improve the potential ability of particular natural compounds for artificial wood protection against biological decay.
