Contribution to the Knowledge of Mycobiota of the Wielkopolski National Park (W Poland)

The Wielkopolski National Park is located in western Poland, near Poznań City. Its unique postglacial landforms are covered with various (semi)natural and anthropogenic ecosystems. The mycobiota of this Park has been studied for 90 years; however, current state knowledge is still insufficient. In 2018, a few-year- long project on the chorology, richness, and diversity of fungal biota of this area was started. In the first year, 312 taxa of macromycetes were found. Among them, 140 taxa were new for the biota of the Wielkopolski National Park. Five species (Botryobasidium robustius, Hebeloma subtortum, Leccinum brunneogriseolum, Pachyella violaceonigra, and Sistotrema athelioides) were new for Poland, and 26 taxa were new for the Wielkopolska region

Leucocoprinus lilacinogranulosus (Henn.) Locq. in Poland

The paper presents the first finding of Leucocoprinus lilacinogranulosus in Poland, the rare, exotic fungus, sporadically found in Europe. The species was found indoors, on soil in terrarium. A description based on the specimens from Poland as well as photographs and microcharacter drawings are presented

New localities of Sarcodontia crocea (Polyporales, Basidiomycota) in Poland

Sarcodontia crocea is a fungus relatively rarely recorded in Central and Northern Europe, where as a parasite it grows mainly on old apple trees. The most recent data on the occurrence of this fungus in Poland are presented in this study. Seven new localities of S. crocea are reported, found in the regions of Mazowsze, Podkarpacie, Ziemia Łódzka, and Żuławy Wiślane in the years 2013–2016. The S. crocea basidiomes were recorded on 12 apple trees. The fungus occurrence on Malus pumila ‘Niedzwetzkyana’ was documented for the first time. Four beetle species representing four families were found in the studied S. crocea basidiomes. Their feeding on S. crocea has not been mentioned in the literature so far

Macrofungal diversity of greenhouses at the Warsaw University Botanic Garden

In 2019–2020 (for 13 months), 21 macrofungi species, both native (14) and inadvertently introduced from warmer regions (7), were found in greenhouses at the Warsaw University Botanic Garden. These included 13 species recorded for the first time in Polish greenhouses. Descriptions and photographs are given for 5 species identified, which are new to Poland (Gymnopus luxurians, Hemimycena ignobilis, Leucoagaricus meleagris, L. rubrotinctus, and Xylaria arbuscula s.l.). The highest variety of species was found in the greenhouses with the collection of tropical and succulents and cacti, with 11 and 8 species, respectively. The number of species ranged from five to four in other greenhouses. The current results increase the number of species reported from greenhouses in Poland to approximately 50. None of the identified species has a negative impact on the growth and health of plants in the greenhouses at the Warsaw University Botanic Garden and at present none of them are indicated as potentially invasive

Macromycetes of the Palace Park in Poznań-Radojewo (Wielkopolska Region, Poland)

This work aimed to present the diversity of fungal species in the Poznań- Radojewo park. It was characterized based on literature data, unpublished master’s theses, the authors’ data, as well as data collected during two mycological trips organized by the Mycological Section of the Polish Botanical Society. Between 1980 and 2017, as many as 333 species of macromycetes have been found within the park in Poznań-Radojewo (among them 19% are rare and endangered), including eight protected species (Mitrophora semilibera, Morchella esculenta  (var. esculenta and var. umbrina), Geastrum corollinum, G. fornicatum, Hericium coralloides, and Myriostoma coliforme), as well as two species new to the Polish mycobiota: Psathyrella bipellis and P. larga. The park in Poznań-Radojewo is very important for maintaining a high species diversity of fungi within the city of Poznań. During revitalization works, it is of paramount importance to take the needs of rare, threatened, and protected species under consideration and to preserve the natural character of plant communities. It is also vital to ensure the presence of coarse woody debris at different decomposition phases, which serves as an important substratum type for rare fungi

Contribution to the knowledge of mycobiota of the Western Sudety Mountains and Western Sudety Foothills (SW Poland). Part 1

The paper presents the results of several years of mycological studies carried out in Poland, in the Western Sudety Mountains (the Karkonosze, Kaczawskie, Izera, and Rudawy Janowickie mountains), Western Sudety Foothills (the Izerskie and Kaczawskie Foothills), and adjacent regions, such as the Jelenia Góra Valley, Lubawska Gate, and Sudety Foreland (the Niemczańsko-Strzelińskie Hills). During the study, the presence of 985 fungal taxa (species, varieties, and forms) was recorded; of these, 66 had hitherto not been observed in Poland

Contribution to knowledge of the mycobiota of Kampinos National Park (Poland): part 2

Continuation of the mycological study of the fire-damaged pine forest in Kampinos National Park in central Poland in 2017 produced interesting new findings. Among the taxa collected, 36 were new to the park, six had not been hitherto reported from Poland (Calycellina araneocincta, Ciliolarina aff. laetifica, Clitocybe metachroides, Galerina cerina f. longicystis, Parasola cuniculorum, Pleonectria pinicola), and the previous status of one taxon (Pleonectria cucurbitula) had been uncertain. Short descriptions based on collected specimens have been prepared for all taxa new to Poland. The current number of taxa of macromycetes identified in Kampinos National Park has reached 1,604

New localities of Sarcodontia crocea (Polyporales, Basidiomycota) in Poland

Sarcodontia crocea is a fungus relatively rarely recorded in Central and Northern Europe, where as a parasite it grows mainly on old apple trees. The most recent data on the occurrence of this fungus in Poland are presented in this study. Seven new localities of S. crocea are reported, found in the regions of Mazowsze, Podkarpacie, Ziemia Łódzka, and Żuławy Wiślane in the years 2013–2016. The S. crocea basidiomes were recorded on 12 apple trees. The fungus occurrence on Malus pumila ‘Niedzwetzkyana’ was documented for the first time. Four beetle species representing four families were found in the studied S. crocea basidiomes. Their feeding on S. crocea has not been mentioned in the literature so far
