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:
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:
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.

Evaluation of the fungicidal properties of essential oils from Leptospermum scoparium and Azadirachta indica in relation to selected fungi causing wood decay. The publication presents the results of evaluation of the fungicidal effect of two essential oils from Leptospermum scoparium (manuka) and Azadirachta indica (neem) on fungi that cause the decomposition of Trametes versicolor and Coniophora puteana wood. Research results indicate that the growth of the tested fungi is clearly inhibited with the participation of the highest concentrations of essential oils used. At the same time, it was found that the action of neem oil was stronger compared to the Traetes versicolor fungus. In contrast, manuka essential oil has a stronger inhibitory effect on the growth of Coniophora puteana.
Ocena właściwosci grzybobójczych olejków z Leptospermum scoparium i Azadirachta indica w stosounku do wybranych grzybów powodujacych rozkład drewna. W publikacji przedstawiono wyniki oceny działania fungicydowego dwóch olejków eterycznych z L. scoparium (manuka) i A. indica (neem) na grzyby powodujące rozkład drewna Trametes versicolor i Coniophora puteana. Rezultaty badań wskazują, że wzrost testowanych grzybów jest wyraźnie hamowany przy udziale największych z zastosowanych stężeń badanych substancji chemicznych. Jednocześnie stwierdzono, że działanie olejku neem było mocniejsze w stosounku do grzyba T. versicolor. Z kolei olejek manuka działał silniej inhibujaco na wzrost grzyba C. puteana.

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:
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:
The paper reports the laboratory research on the natural wood resistance against white pattern fungal wood decomposition. Wood samples of 25, both European and exotic, tree species were collected and used (tab. 1). All samples were dried and weighted, then put on the mycelium of four different white rot causing fungi species: Fomes fomentarius ((L.: Fr.) Kickx), Schizophyllum commune (Fr.: Fr.), Stereum hirsutum ((Willd.: Fr.) Gray) and Trametes versicolor ((L.: Fr.) Pilát). After 30, 60 and 90 days of exposition the samples were put out, cleaned, dried and weighted again. The weight loss indicated the range of wood decomposition and allowed to estimate its natural resistance against fungal wood decay. The results showed that in laboratory conditions the range of all fungi species trophic abilities were much wider than the one observed in nature. Examined fungi were able to destroy wood from trees they never occur on. The reasons of this could be both mechanical (the absence of bark – natural barrier for fungi) and chemical (the less of chemical substances occurring in wood of living trees that could be responsible for its natural resistance against fungi).

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 aim of the study was to characterize the state and dynamics of dead wood resources in the stands of the Świnia Góra strict forest reserve, which was excluded from use for a longer period of time (from 1938/1953), and to compare the results with the state and dynamics of living trees resources. The reserve covers 51 hectares of an upland forest in the Świętokrzyska Forest (central Poland). Data was collected in 2000, 2007 and 2014 on 95 systematically distributed 500 m2 sample plots. The location and dimensions of living trees, standing dead trees (snags, including stumps) and downed trees (logs) on each sample plot were determined and measured. The decay stages of dead wood were estimated using a four−point scale classification. The average volume of dead wood was 198 ±32 m3/ha (43 ±8% of living trees) in 2000 and 138 ±17 m3/ha (24 ±3%) in 2014 (fig. 1). The ratio of the volume of snags to logs decreased from 30 ±5% in 2000 to 24 ±6% in 2014. Silver fir was the dominant species among both living and dead trees (fig. 2). The share of dead wood volume in decay stages 1 and 2 was the highest among snags, while in stages 2 and 3 – among logs. The number of highly decomposed wood increased in the period 2000−2014 (fig. 3). The decay rate of wood calculated over a 7−year period was more rapid for logs (fig. 4). In the period of 14 years, 119 ±23 m3/ha of dead wood underwent a complete decomposition. Volume of trees that died within that period was 59 ±10 m3/ha (fig. 5). The complete decomposition of snags amounted to 64 ±10% and logs to 58 ±5% of the initial dead wood volume. The dead wood resources in the investigated period were not balanced: the amount of decayed wood was larger than the amount of wood replenishing the resources. The lack of this balance was due to the lack of the balance of living trees – dead wood resources were insufficiently replenished by trees that had died during analysed 14 years. The dead wood resources at a level of approximately 200−230 m3/ha might be balanced via their continuous replenishment by newly died trees in the amount close to the current volume increment.

Opis:
Black alder is an important forest−forming species in Poland. Its wood is decomposed by many species of fungi. Ganoderma lucidum (Curtis) P. Karst. is a species of Basidiomycetes which belongs to family Ganodermataceae, order Polyporales. This fungus causes white rot decay of wood in dead and sometimes living alder trees. G. lucidum has been under partial protection in Poland since 2014. It is also red−listed as a rare species (category R – taxa with small populations) on the ‘Red list of the macrofungi in Poland’. The fungus was cut out with a sizeable fragment of wood from the alder stump in Łuków Forest District (eastern Poland) and transported to the laboratory of the Department of Mycology and Forest Phytopathology, Warsaw University of Life Sciences−SGGW. Pure culture of G. lucidum mycelium was obtained from a fragment of fruitbody. The aim of this study was to investigate, through laboratory decay tests, the ability of G. lucidum to degrade alder wood. Sterilization of wood samples (30×20×20 mm) consisted of placing the material in an accelerator and irradiating it with high−energy electrons at a dose of 30 kGy at the Institute of Nuclear Chemistry and Technology in Warsaw. On the next day, wood samples were put into 200 ml flasks with mycelium of G. lucidum on agar−wort medium (2 samples per flask). The flasks were placed in a Heraeus BK 600 incubator for 180 days, with a constant temperature of 22°C and humidity of 80 ±5%. Every 30 days 10 flasks were randomly selected, i.e. 20 samples of alder wood from this experiment. After each incubation period the samples were removed from the flasks, cleaned to remove mycelia and dried at a temperature of 105°C until they reached constant weight. By comparing mass of the samples at the start and the end of experiment in an absolutely dry state, the relative wood mass loss was calculated. After exposure times 180 days, the relative weight loss of alder wood as a result of decay by G. lucidum mycelium was on average 10.88%. The rate of the decay was almost constant during the study period. On some alder wood samples structures resembling fruitbodies of G. lucidum were noticed.

Opis:
Species of the genus Ganoderma are an example of some of the most thoroughly studied representatives of Basidiomycota both in terms of chemical composition and biological activity. Among the compounds found in this kind, the therapeutic effect is primarily associated with the polysaccharides that are heteroglycans or β-D-glucans and terpenoids represented mainly by triterpenes. Triterpene compounds have a structure composed of 30 carbon atoms, usually forming a system of five six-membered rings. Characteristic of these structures are functional groups (hydroxyl, carboxyl or ketone) and double bonds. Mycochemical studies have led to the isolation of numerous triterpenes of the lanostane type (ganoderic acids, aldehydes, alcohols, esters), lucidenic acids and others from various species of the Ganoderma genus. The broad spectrum of biological activity determined by triterpene compounds includes anti- tumor, anti-inflammatory, antioxidant, hepatoprotective, antidiabetic, and antiviral effects. This work describes biologically active triterpenes in selected species of the genus Ganoderma: Ganoderma lucidum, Ganoderma applanatum, Ganoderma adspersum, Ganoderma pfeifferi, Ganoderma colossum and others. These species are sources of natural compounds valued for thousands of years in the traditional medicine of the Far East, while ongoing research has confirmed their medicinal properties nowadays.

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.
