Opis:
This review is based on our observations and detailed studies conducted in more than 100 bare−root forest nurseries in Poland. We concentrated on recent work on ectomycorrhizal community structure of most common forest trees (pine, spruce, larch, oaks, beech and birch). The following issues are addressed: fungal diversity, host specificity and age, ascomycetes or basidiomycetes predominance, and exploration types of mycorrhizae as well as edaphic factors.

Opis:
The effects of tree genotype on below−ground ectomycorrhizal fungal communities of 40 years old European larch from Kowary, Bliżyn, Świętokrzyski National Park and Szczytna Śląska origins was investigated. The research was carried out in the provenance trial in the Experimental Forestry Unit in Krynica Zdrój (Beskid Sądecki Mountains, S Poland). Ectomycorrhizal fungal communities were assessed by a combination of morphological and molecular techniques. In total 22 fungal taxa has been distinguished (from 17 to 20, depending on larch provenance). Thirteen ectomycorrhizal fungal taxa were common to all analysed origins. The mean taxa richness, Shannon diversity and Simpson dominance coefficient did not differ significantly between provenances. Based on fungal taxa composition (Jaccard coefficient) tested larch origins were characterized by a high level of similarity of ectomycorrhizal fungal communities. Six detected fungal taxa have not been previously reported as symbiotic partners of European larch.

Opis:
Indigenous mycorrhizal colonisation of one (1/0) and two (2/0) year old Scots pine (Pinus sylvestris L.) seedlings from forest nurseries situated in the north-west part of Poland was investigated. Seedlings were fertilized after a schedule designed to satisfy their requirements which resulted from soil analysis of each nursery. In autumn needle nitrogen concentration and mycorrhizal status were estimated. As a rule seedlings 1/0 obtained high doses of fertilizers, and their needle nitrogen concentration highly exceeded the recommended optimal level above which mycorrhiza formation is greatly restricted. Highly negative correlation was found between the nitrogen status of foliage and mycorrhizal quantitative and qualitative colonisation estimated in the abundance class of 0-5. When internal nitrogen level was low, several ectomycorrhizal morphotypes were found on roots of tested plants. Excessive nitrogen fertilization decreased root ramification pattern and along with increased pH promoted ectendomycorrhizal symbiosis. Two-year-old seedlings (2/0) were characterised by significantly lower nitrogen concentration in the needles which resulted in much higher ectomycorrhizal colonisation. Ectendomycorrhizal symbiosis in the case of 2/0 seedlings was scarce. The results indicate that natural colonisation in nurseries is dependent on the soil management practices, especially nitrogen fertilization. Optimalization of nitrogen fertilization may intensify ectomycorrhizal colonisation of the nursery stock from indigenous fungal species and improve the growth of Scots pine seedlings in bare-root nurseries and plantations.

Opis:
Pedunculate oak (Quercus robur L.) is among the major managed tree species in Europe. In Poland, oak woodlands cover 6.9% of forest area. Furthermore, the significance of native oaks for Polish forestry is rising because the Polish National Forest Strategy predicts a growth of forest cover from 28.5% to 33% by year 2050 with the primary focus on the increase in contribution of deciduous tree species (from 22% to 33%). Therefore, for establishment of new stands, oak seedlings are grown for 2−3 years in forest nurseries. For optimal growth and development all European oak species are critically dependent on ectomycorrhizal fungi. The objective of this study was to describe the temporal dynamics of ectomycorrhizal community of pedunculate oak seedlings during the first year of growth in bare−root forest nursery. Experiment was conducted in forest nursery Miranowo (western Poland). The species structure of an ectomycorrhizal community was assessed every 10 or 15 days from May till October. Mycorrhizal colonization of tested seedlings changed from 0 to 85% depending of the time of sampling. Based on combination of morphological and molecular techniques, nine ectomycorrhizal fungal taxa were distinguished. The first ectomycorrhizas formed by Scleroderma verrucosum were detected 50 days after acorns sowing. In the next sampling days ectomycorrhizal community was dominated consecutively by Inocybe curvipes and Hebeloma sacchariolens (with maximum of abundance 60.98 and 75.55%, respectively). The obtained results were strongly influenced by the infection with the fungal biotroph Erysiphe alphitoides and resulted in a dramatic reduction in the abundance of living ectomycorrhizas down to 7.5%. Our investigation revealed that ectomycorrhizal fungal community of pedunculate oak seedlings during the first year of growth in bare−root forest nursery is rich in terms of number of species and a temporal changes are very dynamic. Thus we suggest, that in case of pedunculate oak artificial inoculation in general is not necessary for oaks seedlings in nursery practice.

Opis:
Mycorrhizal syntheses of pine seedlings were conducted with Suillus luteus (L.) S.F. Gray, a strain No 14 characterised by high tolerance to Al3+ ions and a strain No 62, sensitive to aluminium. The experiment was performed as a semi-sterile culture in a peat-perlite medium with Al3+ ion concentration of 11 mM. Abundant coralloid and cluster mycorrhizas of S. luteus were formed on roots of the inoculated plants at the beginning of the experiment. Aluminium treatment limited mycorrhizal morphotypes to single and dichotomous and significantly reduced the total number of mycorrhizal tips but had no effect on extramatrical mycelium development in the potting substrate. Al treatment did not affect growth of the above-ground part of the tested plants but significantly reduced root growth of mycorrhizal seedlings. The effect of Al on the internal nutrient status was variable and not very much pronounced. A considerable amount of Al was absorbed by the roots and translocated to the shoots. Mycorrhiza formation with both strains of S. luteus did not prevent Al3+ translocation to the upper parts of the tested seedlings. The results suggest that low pH and high Al availability may harmfully influence mycorrhizal symbiosis of Scots pine (Pinus sylvestris L.) by anega tive effect on fine-root production and fewer short root tips available for colonisation rather than through a direct negative effect of Al3+ ion concentrations on extramatrical mycelium in the soil.
Syntezę mikoryzową siewek sosny (Pinus sylvestris) z odpornym naglin szczepem Suillus luteus nr 14 i wrażliwym na glin szczepem nr 62 przeprowadzono w warunkach półsterylnych w szklarni. Po nawiązaniu mikoryzy siewki przez 6 miesięcy traktowano roztworem glinu o stężeniu 11 mM przy pH = 3,8. W warunkach kontrolnych (bez glinu) oba szczepy S. luteus tworzyły obfite mikoryzy pojedyncze oraz dichotomicznie i koralowato rozgałęzione. Traktowanie glinem zredukowało morfotypy mikoryzowe do pojedynczych i dichotomicznych oraz znacząco zmniejszyło całkowitą liczbę wierzchołków mikoryzowych na korzeniach siewek, ale nie ograniczyło rozwoju grzybni ekstramatrykalnej. Wwarunkach kontrolnych (bez glinu) rozwój grzybni ekstramatrykalnej, mierzony zawartością ergosterolu w podłożu był podobny w przypadku obu testowanych szczepów. Traktowanie glinem spowodowało pewien wzrost rozwoju grzybni ekstramatrykalnej szczepu tolerancyjnego i nieznaczne zahamowanie wzrostu szczepu wrażliwego. Glin ograniczył znacząco wzrost korzeni, natomiast nie stwierdzono negatywnego wpływu glinu na wzrost części nadziemnych siewek. Siewki traktowane glinem absorbowały w korzeniach znaczne ilości tego metalu, który był także przemieszczany do pędów. Stwierdzono niewielki wpływ glinu na zawartość pierwiastków mineralnych w siewkach. Badania wykazały, że przy zastosowanym wysokim stężeniu glinu szczep Nr 14 wyselekcjonowany w warunkach in vitro jako odporny na glin, nie zahamował przemieszczania jonów Al3+ do części nadziemnych siewek sosny. Wyniki sugerują, że szkodliwe działanie jonów glinu na symbiozę mikoryzową w warunkach niskiego pH polegara czej naogra niczeniu liczby wierzchołków korzeni drobnych, które potencjalnie mogą tworzyć mikoryzy, niż nabezpośrednim wpływie na grzybnię mikoryzową.

Opis:
Hymenochaete cruenta is a saprotrophic fungus, grown mainly on the bark of dead branches and trunks of Abies trees and thus the distribution of this fungus in Poland and other European countries is closely connected with natural range of silver fir. Despite its wide range, H. cruenta is considered as rare in the whole area of its occurrence. In this paper, we present a new locality of H. cruenta, discovered in May and September 2016 in the Olbina nature reserve (southern Wielkopolska Lowland, Kalisz Forest District). Ecological notes and macro- and microscopic feature of basidiocarps of this fungus are presented. Additionally, the current distribution of H. cruenta in Poland comprising 78 localities is provided. The rank of H. cruenta among threatened species categories in different European countries is discussed. It seems that the species is rare and threatened in Poland, and it should be still classified as “vulnerable” on the red list of macrofungi. The significance of H. cruenta for diversity of mycobiota and the necessity of further research on the dynamic of occurrence of H. cruenta inside and outside of the natural range of A. alba is underlined.

Opis:
Biomass of extramatrical mycorrhizal mycelium (EMM) was examined under canopies of mature Norway spruce trees grown in different forest stands in Poland. Two mountain forest sites (Brenna and Salmopol), one upland site (Zwierzyniec) and one lowland site (Mirachowo) have been investigated, using sand-filled mesh-bags method. The in-grow mesh-bags were buried in the soil for 12 months (since October up to the next October) or for 4 months (since June up to October) at four depths at each site: 5, 15, 30 and 45 cm (Brenna and Salmopol) or 60 cm (Zwierzyniec and Mirachowo). The mycelium biomass was estimated from the ergosterol content determined in the mesh-bags. The results indicated significant differences in EMM production and their vertical distribution between the mountain and the upland and lowland forest sites. The lowest EMM biomass was found at the experimental plot in the mountainious site Brenna. Considerable decrease of EMM biomass with the soil depth was recorded after 12 months of the mesh-bags incubation in soil in the upland and lowland sites, while in the mountain forests decrease of the EMM biomass in the lower soil depths diminished more gradually EMM biomass determined in the mesh-bags placed in soil at the upper 5 and 15 cm tended to be higher after 4 months than after 12 months of incubation period. Such results suggest that the time necessary for evaluation of EMM biomass in soil may be limited to the summer–autumn months, when the production of EMM is the highest. Variable stress factors can influence decreased ectomycorrhizal mycelium production and/or their destruction. Further research in different forest types and regions are needed for better understanding factors determining EMM biomass production and surviving in soil.

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 effects of pine and oak forest litter on mycorrhizal status of 2−year−old Pinus sylvestris L. seedlings grown in a bare−root nursery was investigated. The research was carried out in the nursery of Vilnius University Botanical Garden in Lithuania. Ectomycorrhizal communities were assessed by a combination of morphological and molecular techniques. Statistical analysis revealed significant effect of litter treatment on some growth parameters of seedlings: seedling height, needle dry weight and total seedling weight. The survival rate of seedlings was significantly highest for oak litter, intermediate for pine litter, and lowest for control soil. Pine seedlings were colonized by indigenous ecto− and ectendomycorrhizal symbionts. Seven mycorrhizal species (Suillus luteus, S. variegatus, Wilcoxina mikolae, Tuber sp., Tomentella sp., Cenococcum geophilum, Amphinema byssoides) were distinguished on the roots of pine seedlings as well as one ectomycorrhizal symbiont not identified to species level. In total, 6 mycorrhizal types were found in control soil, 5 in pine litter, and 8 in oak litter. Suilloid (S. luteus and S. variegatus) and Wilcoxina mycorrhizae were dominant on tested seedlings, irrespective of litter addition. Seedlings grown in untreated nursery soil were 34% colonized by W. mikolae, while suilloid mycorrhizae were dominant after litter treatment (81% in pine litter and 63% in oak litter). We may conclude that suilloid mycorrhizae are better adapted to the conditions related to litter addition than W. mikolae.

Opis:
This paper presents the second part of the results of the first short-term inventory of fungi species occurring in the Biebrza National Park and is focused on a survey of macrofungi. The total number of macrofungi found during the survey in late August 2012 was 289 taxa: 17 ascomycetes and 272 basidiomycetes, inhabiting diverse ecological niches. The identified fungi belonged to ectomycorrhizal symbionts and saprobionts decomposing wood, plant litter and animal remnants. The identity of 25 mycorrhizal fungi species has been confirmed using molecular techniques. Five species are newly reported for Poland (Amanita olivaceogrisea, Lepiota lepida, Stropharia alcis, Xerocomus fennicus, X. cisalpinus) and 225 taxa (79 %) were not known in the Biebrza National Park. Fifty nine species are endangered in Poland, of which nine species are protected by law. Data on species richness and the taxonomic diversity of the identified fungi are briefly commented in terms of their significance for nature conservation and future research.
Prezentowane dane są wynikiem badań prowadzonych w dniach od 28 sierpnia do 1 września 2012 w ramach sesji terenowej Polskiego Towarzystwa Mykologicznego. Celem była wstępna inwentaryzacja grzybów wielkoowocnikowych występujących na terenie Biebrzańskiego Parku Narodowego (BbPN), terenu niemal zupełnie nie poznanego pod względem mykobioty. W artykule zamieszczono wykaz zidentyfikowanych 289 taksonów (gatunków, odmian i form) grzybów workowych i podstawkowych. Wśród znalezionych gatunków są grzyby bardzo rzadkie, znane z zaledwie jednego lub kilku stanowisk w Polsce (16 gatunków), a także wykazane w literaturze z Polski po raz pierwszy (5) oraz zagrożone i objęte ochroną (59), w tym Phellodon confluens – uznawany za wymarły. Jak wskazano w części pierwszej artykułu (Ruszkiewicz-Michalska et al. 2012), badania przeprowadzone w BbPN są pierwszymi z planowanego przez Polskie Towarzystwo Mykologiczne cyklu inwentaryzacji w obiektach objętych różnymi formami ochrony. W wielu takich obiektach (parkach narodowych, rezerwatach, parkach krajobrazowych oraz obszarach Natura 2000) brak jest danych mykologicznych lub są fragmentaryczne albo wymagające aktualizacji. Podstawową przesłanką do prowadzenia badań inwentaryzacyjnych jest potrzeba uwzględniania grzybów w polityce ochrony przyrody, zarówno na obszarze parków narodowych, jak i w szerszej skali.
