    Opis:
    Trametes gibbosa is a widespread polypore fungus occurring throughout Europe and Asia. It is considered a saprotroph occasionally exhibiting parasitic activity. The aims of the present experimental work were to: (1) determine the ability of T. gibbosa pure culture to decompose beech wood under laboratory conditions, (2) test the trophic abilities of T. gibbosa by comparative analysis of the development of its mycelium inoculated into the stems of living beech trees and into beech rollers (stem segments – dead substrate). The laboratory wood decay experiment revealed considerable weight loss of the beech wood samples exposed to T. gibbosa (32.7% after 120 days). Identification of the mycelium used for inoculation in natural forest conditions was done by morphological analysis of the cultures and molecular barcoding. Attempts to recover T. gibbosa mycelium were made after two and eight years for the living trees, and after two years for the rollers. While T. gibbosa could not be reisolated from the inoculated beech trees, basidiomata were observed on the beech rollers, and genetically verified T. gibbosa mycelium was extracted from them. We conclude that T. gibbosa exhibits strong saprotrophic inclinations.

    Opis:
    Globally, tree-holes are important ecological component of forest and woodlands. Numerous microorganisms rely on cavities, both natural and those excavated by primary cavity nesting birds, mainly by woodpeckers, for their survival and reproduction. However, the fungi occurring in cavities are not well characterized. Specifically, very little is known about the fungal communities inhabiting the woodpecker nest cavities. Therefore, in this study, we investigated the fungal diversity of cavities in southern Poland. The samples were collected from freshly excavated woodpecker nest cavities using a nondestructive method (ND). The spatial distribution of fungal communities within the cavities was evaluated by sampling different parts of a single cavity using a destructive method (D). We detected 598 fungal isolates that included 64 species in three phyla and 16 orders using the ND method. Most of the fungi isolated from the cavities represented the phylum Ascomycota (73.9% of the isolates) with 11 orders, and Microascales was the predominant order (30% of the isolates). The most common species detected was Petriella musispora, which was isolated from 65% of the cavities. A total of 150 isolates (25%) were members of Basidiomycota, with Hymenochaetales being the dominant order (16% of the isolates). The basidiomycetous fungi were isolated from 55% of the cavities. Several taxa closely related to the pathogenic fungi and associated with secondary animal infections were detected in the wood of cavities. We identified different fungal communities in the three cavity parts using the D method. The cavity entrance had more number of species than the middle and bottom parts. The results of this study advanced our current knowledge on the mycobiota in woodpecker nest cavities and provided preliminary evidence for tree cavities being the hotspot for fungal diversity.

    Opis:
    The experiment conducted in the Kampinos National Park since 2015 was aimed at assessing the sprouting ability of black cherry (Prunus serotina Ehrh.) in response to different measures of mechanical control and mycobiota colonizing the dying trees. Basal cut-stump, cutting at ca. 1 m above the ground and girdling were performed on 4 terms, two plots and applied to 25 trees, 600 trees in total. Sprouts were removed every 8 weeks since the initial treatment for 4 consecutive growing seasons, except winter-treated trees. At the end of the fourth season of control, 515 out of 600 trees were dead (86%): 81% on Lipków and 90% on Sieraków plot. Among 18 experiment variants with sprouts removal, 17 showed more than 80% of dead trees. The lowest, 76% share, concerned summer cut-stump at the base of the tree. For winter measures, the share of dead trees was lower in all cases and ranged from 28% to 64% proving that sprouts removal contributes to the drop of sprouting strength and quicker dying of the trees. Almost 80% of trees showed sporocarps that represented 51 taxa of macrofungi in total, including 6 Ascomycota and 45 Basidiomycota. The group of six most frequently encountered fungi includes: Hyphoderma setigerum, Bjerkandera adusta, Peniophora cinerea, Armillaria ostoyae, Nectria cinnabarina, Stereum hirsutum. Both plots had similar share of black cherry individuals with sporocarps of macrofungi, that is, 81% and 78% for Sieraków and Lipków respectively. The share of colonized trees and the number of reported macrofungal taxa increased significantly compared to the year following the treatment. In addition, the composition of macrofungi changed with the progressing dying of trees. These results broaden the knowledge about macroscopic fungi colonising and living on black cherry within its secondary range of distribution. Moreover, one macrofungus and two microfungi new for KNP are reported.

    Opis:
    Within the framework of Project no. POIG.01.03.01-30/074/08 “Ionic liquids in innovative technologies connected with processing of lignocellulosic raw materials” the Wood Based Panels and Glues Department of the Wood Technology Institute in Poznan carried out research aiming at application of ionic liquids in particleboard technology. The objective of the research was application of [DDA][NO3] and [BA][NO3] ionic liquids in preservation technology of panels resistant to biotic factors. The method for application of ionic liquids to particleboards, the type and amount of chosen ionic liquids, as well as their influence on standard parameters of the panels were investigated. In the tests the amine resin available on the domestic market and particles obtained from debarked Scots pine chips were used. The results of the research demonstrated that ionic liquids worsened parameters of the panels, but improved their resistance to decay fungi.

Celem badań jest wykorzystanie cieczy jonowych w technologiach zabezpieczania płyt na działanie czynników biotycznych. Dotychczasowe badania obejmowały opracowanie sposobu wprowadzania cieczy do wiórów przeznaczonych do wytwarzania płyt, poznanie wpływu rodzaju i ilości wybranych cieczy jonowych – [DDA]NO3], [BA][NO3] – na standardowe właściwości. Stosowano klejową żywicę aminową dostępną na rynku krajowym i wióry pozyskane z korowanych zrębków sosnowych. Badania wykazały, że zastosowane ciecze jonowe obniżają właściwości mechaniczne płyt, poprawiają natomiast ich odporność na grzyby rozkładu brunatnego.

    Opis:
    Hericium flagellum (Scop.) Pers. is considered a rare, wood-decaying fungus that occurs on coniferous trees, predominantly on silver fir (Abies alba). In this paper, a new locality of H. flagellum in Wielkopolska Voivodship is presented, along with the macro- and micromorphological features of the collected specimens. Basidiomata of H. flagellum were found in November 2016 and 2017 in the “Olbina” nature reserve (ATPOL Dc-97, Kalisz Forest District), located in a continental mixed coniferous forest close to the northern border of the natural range of silver fir. In 2016, H. flagellum was found growing in the hollow of an old stump of silver fir, and in the following year, this fungus was recorded on a fallen log of silver fir. The implications for conservation are briefly presented. Prospects of further development of the basidiomata of H. flagellum in the “Olbina” reserve are also discussed.

    Opis:
    Laricifomes officinalis is a wood-decay fungus that is closely associated with old individuals of Larix decidua. In the twentieth century, L. officinalis was over-harvested because of its medicinal properties; consequently, it has become very rare or almost extinct in the Alps. In this study, we investigated the population of L. officinalis in the Alpe Veglia–Alpe Devero Natural Park (Val d’Ossola, Italy) to assess a preliminary conservation strategy. Population consistency was estimated using field mapping, and spatial analysis was performed on host trees based on topographical and environmental variables. Mycelia were isolated from harvested basidiomata, and strain identity confirmed by molecular analysis of the ITS region. All isolated strains were tested for growth in Petri dishes containing different standard media to determine which strains had the highest growth rates; the fastest growing strains may be selected for future studies and applications. Compared to the control strains from Val Malenco and Parco Nazionale del Gran Paradiso, all strains from Alpe Veglia–Alpe Devero Natural Park had lower growth rates. There was no significant difference between the growth rates of strains from Alpe Veglia and those from Alpe Devero. The results suggest that the population consistency of L. officinalis in the Alpe Veglia–Alpe Devero Natural Park is related to two main factors: habitat preservation and harvesting prohibition. These results confirm the need to protect L. officinalis both inside and outside natural reserves, despite the apparent increase in local populations.

    Opis:
    Wood degrading capacity of lignicolous fungi was studied by decay test. In which two methods were followed, i) wood chips method ii) wood block method. Eight timbers infected by six fungi were selected for studying percentage of decay and biochemical test was done to know delignification. After 12 months, 90 % of wood block of T. arjuna was decayed by L. stereoides. In teak wood 16.82 % of decay was due to H. apiaria in 3 months. As the percentage of moisture was less, percentage of weight loss was also less; this indicated that decay capacity of fungi will depends on % moisture content in wood. The percentage loss in hot water soluble substrates was more in case of T. crenulata due to L. stereoides for 5 months, whereas lowest in case of teak wood decayed by H. apiaria for 5 months. The percentage loss in ethanol benzene soluble substrate was more in case of Adina wood decayed by C. versicolor for 5 months, whereas lowest in case of teak wood infected with L. stereoides for 3 months. As the incubation period increases, percentage loss in acid soluble lignin was more in case of infected woods. L. stereoides, C. versicolor, and H. apiaria showed selective delignification in all infected woods, whereas T. pini showed simultaneous degradation of lignin in all woods tested. The valuable timber like teak wood was not resistant to wood decay because they loss 50% of lignin. The in vitro wood decay test can‟t be taken as absolute evidence for wood decay behavior of lignin-degrading fungi, so we should conform decay of wood by consider biochemical test. For rapid evaluation of wood decay the wood chip method was best suitable. For the first time the wood decay and biochemical test of 8 wood samples infected by white rot fungi like S. commune, L. stereoides, H. apiaria, C. versicolor, T. pini and soft rot fungi like T. viride was studied.

The initial of decaying symptoms were firstly noticed in 2010 which progressed with destructive tissue death of tree trunk. A spongy, sessile, bracket-fungus was found associated with the decay. Morphological and microscopic examination of the collected specimens confirmed the fungus as Phellinus gilvus (Schw.) Pat. Since, P. gilvus is a saprobic fungus having a wide host range worldwide and M. indica is one of the most attacked hosts in India. Therefore, the present report is an important addition to the existing knowledge which will be helpful in understanding the pathogen diversity and interaction with host.

    Opis:
    Changes of physical and chemical properties, mass loss and susceptibility of oak wood to decay caused by Basidiomycetes fungi were assessed after wood samples had been taken out of the sea within the framework of MACHU project. Test samples of oak wood of the dimensions of 250 × 10 × 10 mm were placed in coastal waters of the Baltic Sea at the area of medieval seaport in Puck and in waters of the Gdansk Bay at the same longitude as Orłowo (near the wreck of Swedish warship Solen). The samples taken out of the sea were examined visually and described. Changes in mass of the samples, their bending strength and modulus of elasticity, compression strength along the grain, ability to decay caused by Trametes versicolor fungus, content of mineral substances and substances soluble in water, ethanol-benzene mixture and in 1-percent aqueous solution of NaOH, content of cellulose, lignin and pentosanes as well as pH of the wood were investigated. The properties of samples taken out of the sea after 6 months of immersion were compared with the properties of control twin samples of oak wood which had not been immersed. The results obtained so far indicate that noticeable, measurable changes in oak wood immersed in sea occur already in half a year since immersion, so observation of them may be useful for protection and monitoring of underwater archaeological objects.

    Lignicolous fungi include many wood decay fungi. Studies on molds and decay fungi are necessary to enable us to control their growth on wood and wood products. A survey was undertaken during 2012-2013 to detect the various ligniclous fungi in Andhra Loyola College, Vijayawada and Krishna District, Andhra Pradesh. In a recent study, lignicolous fungi were collected from living trees and fallen branches from Andhra Loyola College, Vijayawada, India. On the basis of occurrence Coriolopsis aspera (Junghuhn) Teng. Fulvifomes nilgheriensis (Montagne) Bondartseva & S. Herrera, Ganoderma australe (Fr.) Pat., G. lucidum (Curtis) P. Karsten, Hexagonia apiaria (Pers.) Fr. Phellinus linteus (Berk. & Curt.) Teng. Trametes cingulata Berk. Hook., T. cotonea (Pat. & Har.) Ryv. T. gibbosa (Pers.) Fr. Schizophyllum commune Fr. were reported from Krishna district for the first time. F. nilgheriensis (Montagne) Bondartseva & S. Herrera is recorded for the first time from India. Even though being preliminary, our results point to the necessity of conservation and protection of recent fungal diversity but, in our opinion, not by making so-called “Red list of endangered species", which, due to the lack of information and very poor evidence on this group of organisms in the region under the consideration, are extremely unreliable and therefore disputable, but rather through the very short list of few not endangered species, conditionally called “White list of not endangered fungal species", if such species recently exist at all.

    Opis:
    Inonotus rickii (Pat.) Reid is a pathogenic wood-decaying fungus that causes severe decay in several ornamental urban trees in Europe. It has been known to occur on different hosts in Sicily (Italy) since 1985, and in Rome (Italy) since 2003. Some physical and mechanical wood features were studied according to the standards in order to propose an investigation methodology to set a deterioration ranking of urban trees. In this phase of the study, Celtis australis L., Acer negundo L., Acer campestre L., Robinia pseudoacacia L., Tilia × vulgaris Hayne, Ulmus minor Mill., Platanus × acerifolia (Aiton) Willd. and Quercus ilex L. were studied. The data were analyzed using ANOVA and M-ANOVA tests to check the differences among the specimens. A risk matrix was created in order to combine the features that showed statistical differences between the control specimens and the inoculated specimens, in order to establish, in vitro, a degradation ranking among the wood species. The wood species which showed no in vitro durability to I. rickii, were the same ones that displayed susceptibility in the living trees.

    This work deals with decay resistance and selected physical and mechanical properties of wooden composites (WCs) prepared from 3.6 mm thick three-layer beech plywood and 0.6 mm thick decorative surface veneers of selected exotic (aningr´e, bubinga, iroko, khaya, padouk, sapelli, weng´e) and domestic (beech, European oak, sweet chestnut, walnut) wood species. Joining of veneers in the plywood and then also in the WCs was carried out by pressing processes using the PF glue Fenokol 43. The aim of the experiment was to determine the influence of surface veneers of different natural durability on rotting of the WCs, and on resistance of the WCs to water and mechanical loadings, as well. Decay resistance of individual veneers and WCs was tested by modified EN 113 against the brown-rot fungi Serpula lacrymans or Coniophora puteana, and the white-rot fungi Phanerochaete chrysosporium or Trametes versicolor. Weight losses of individual types of veneers and WCs caused by wood-destroying fungi were compared with weight losses of beech-veneer and beech-WC, respectively. The lowest weight losses at rotting processes showed the padouk-WC, i.e. WC prepared from the beech plywood and two the most durable padouk surface veneers. Density, water soaking, water swelling, tensile strength perpendicularly to the plane (?), and bending characteristics (MOR, MOE) of all WCs were determined in accordance with European standards. These physical and mechanical properties of the WCs were only partly influenced by the type of surface veneers. Selected types of the WCs, e.g. padouk-WC, could also be convenient for exterior expositions out of ground contact.

    Opis:
    Timer decay is caused by primarily enzymatic activities of microorganisms. For the first time fungal diversity of timber degrading fungi was studied in Gujarat, India. Timber Degrading Fungi belonging to Aphyllophorales are economically important as many of these cause serious damage in sawmills of Gujarat. To find out the association of the timber degrading fungi and timber decay problems in sawmills a survey was conducted during 2007 to 2011 in different sawmills of 5 districts of Gujarat i.e. Vadodara, Ahmedabad, Bharuch, Rajkot and Jamnagar. In the present study teak wood present in sawmills was infected with 14 types of fungi in which Lenzites sterioides and Trametes versicolor damaged the wood severely was reported for the first time. In all 94 sawmills were surveyed, the 28 sawmills were from Vadodara, 29 from Ahmedabad, 12 from Bharuch, 21 from Rajkot and 4 from Jamnagar. Out of 94 sawmills survyed, 84 sawmills were having timber rotting fungi associated with wood. Maximum fifteen and thirteen fungal species were observed in saw mills of Chhani road, followed by 11 in Station road, 7 in Dhabhoi road and 6 in Harni, Vadodara. Fours woods uninfected are Beyo, Marinty, Ash, and Arjun. Fourteen different types of fungi were found associated with teak, followed by seven in pinus, madhuca, Acacia nilotica, six in babul, neem, four in tamarind, Pithacoelobium and three in mango, Eucalyptus, African Mahagoni, Kapoor, Peltophoram rouxburghii, Derris pinnata wood respectively. The commonly observed timber decaying fungi were Schizophyllum commune, Flavodon flavus and Ganoderma lucidum belonging to Basidiomycota. Ascomycota members included was Daldinia concentrica and Xylaria polymorpha.

    Opis:
    The aims of the study were to identify the fungi associated with the decay of thin roots (1-5 mm) of 1, 3 and 15-year-old Fraxinus excelsior plants and to estimate the pathogenicity of certain fungi. In total, 400 fungal isolations were performed from which 334 cultures were obtained. Altogether, 26 species of fungi were identified. The following species were most frequently obtained, independently of plant age and origin: Alternaria alternata, Chaetomium globosum, Cryptosporiopsis sp., Fusarium oxysporum, F. solani and Cylindrocarpon destructans. The last three of these were then used in an inoculation test. F. oxysporum caused the death of over 80% of 2-month-old seedlings grown in boxes containing perlite and kept in a growth chamber.

    Opis:
    Rozkład drewna w przyrodzie wywołany jest głównie przez grzyby „białej zgnilizny” z klasy Basidiomycetes, do których należy Phanerochaete chrysosporium. Celem pracy było zbadanie produkcji enzymów ksylanolitycznych w hodowli P. chrysosporium w pożywce mineralnej Czapeka z dodatkiem słomy lub otrąb pszennych. Wyniki badań wykazały, że P. chrysosporium wytwarza enzymy ksylanolityczne (endo-1,4-β- ksylanazę i β-ksylozydazę) w pożywce hodowlanej z dodatkiem obu substratów. Aktywność endo-1,4-β-ksylanazy i β-ksylozydazy zależy od temperatury i jest najwyższa odpowiednio w 70 i 60oC. Maksymalną aktywność obu enzymów stwierdzono w odczynie kwaśnym, pH = 4,6.
    Degradation of wood in nature is caused mainly by white rot fungus representing Basidiomycetes, such as Phanerochaete chrysosporium. The aim of this studies was to investigate the production of xylanolytic enzymes (endo-1,4-β-xylanase and β-xylosydase) by Phanerochaete chrysosporium cultivated on Czapek mineral medium to which straw or wheat bran was added. The results showed that P. chrysosporium produced both enzymes endo-1,4-β-xylanase and β-xylosydase in culture medium with the two substrates added. The activity of endo-1,4-β-xylanase and β-xylosydase depends on temperature and it is highest at 70 and 60oC. The maximum activity of both enzymes was found for the acid reaction, pH = 4.6.

    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:
    Lupine diseases caused by pathogenic fungi constitute a serious problem in agriculture. They lead to partial yield loss and deterioration of crop quality through the changes in biochemical composition of seeds or their contamination with mycotoxins. Some of common lupine diseases are fusarioses caused by Fusarium oxyspomm f. sp. lupini. Morphometric and metabolic changes were investigated in yellow lupine seedlings infected with F. oxyspomm f. sp. lupini. It was found that infection caused temporary inhibition of seedling growth, overcome at later development, and activation of ß-glycosidase and peroxidases. The changes in enzymes activity indicate the induction of defense mechanism against F. oxyspomm f. sp. lupini and inhibition of pathogen spread.
    Choroby łubinu powodowane przez grzyby chorobotwórcze stanowią poważny problem w rolnictwie. Prowadzą do zniszczenia części plonu oraz pogorszenia jego jakości, poprzez zmiany w składzie biochemicznym nasion lub zakażenie ich mykotoksynami. Do powszechnie występujących chorób łubinu zaliczane są fuzariozy powodowane przez Fusarium oxysporum f. sp. lupini. Badano zmiany morfologiczne oraz metaboliczne w siewkach łubinu żółtego infekowanych F. oxysporum f. sp. lupini. Stwierdzono, że infekcja spowodowała okresowe zahamowanie wzrostu siewek, przełamane w dalszej fazie ich rozwoju oraz aktywację ß-glikozydazy oraz peroksydaz. Poinfekcyjne zmiany aktywności enzymów wskazują na uruchamianie mechanizmu obronnego względem F. oxysporum f. sp. lupini i zahamowanie rozprzestrzeniania się patogena.
