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.

We identified 17 species of fungi that are new to Kampinos National Park. Sixteen were found during surveys of areas damaged by a strong wind in 2017. The remaining species was found outside the windthrow area. Descriptions of four species new to Poland ( Cortinarius subcompar , Hyaloscypha quercicola , Hypocrea tremelloides , and Trechispora aff. invisitata ) are also provided. The current number of macromycetes taxa identified in Kampinos National Park is 1,654.

The paper presents eleven species of fungi new to the Kampinos National Park. They were found during the studies on wind-damaged areas after the forest was damaged in 2017. Two species new to Poland were described and illustrated ( Nectria nigrescens and Strossmayeria basitricha ). The current number of macromycetes taxa known from the Kampinos National Park has reached 1,637.

This paper presents 18 species of fungi that are new to the Kampinos National Park and their buffer zone. Seventeen of these species were found during studies on wind-damaged areas after the forest was damaged in 2017. One species new to Poland has been described and illustrated (Odonticium septocystidiatum). A few of the species recorded (Ciliolarinacfr.laricina,Daldinia petriniae,Pseudovalsa umbonata,Spongipellis litschaueri) are very rare in Poland and hitherto mentioned from single localities in the country. Two species from the Polish red list of macrofungi were recorded in the Kampinos National Park for the first time – namely,Punctularia strigosozonata(E) andTrichaptum biforme(R). The current number of macromycete taxa known from Kampinos National Park has reached a total of 1,630.

Wielkopolski National Park is a protected area located in central Wielkopolska, near Poznań City, and is an important refuge to numerous valuable species of plants, fungi, and animals. Through 2019, the project to recognize and catalog the macromycetes of this Park was continued. The current paper presents the results of these studies in the form of an annotated list of the recorded species. One hundred and eighty-nine taxa new for Wielkopolski National Park have been identified. Among these, nine are new to Poland (Acanthophysellum lividocoeruleum, Agaricus moellerianus, Callistosporium luteo-olivaceum, Entoloma terreum, Flammulina populicola, Leucoagaricus sublittoralis, Marasmius anomalus var. microsporus, Phaeohelotium rufescens, and Tulasnella danica). The current number of fungal taxa found in this park is 1,122.

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.

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.

The Bieszczady Mts, a mountain range in SE Poland, is a hot spot of fungal richness and diversity in Poland. This paper summarizes 5 years of studies in the Bieszczady Mts, as well as previously published research. A total of 1,377 macromycetes taxa were found, including many (464) which were protected, red-listed, or very rare in Poland. Thirty-eight taxa (nine Ascomycota and 29 Basidiomycota) have been reported in Poland for the first time: Agrocybe gibberosa, Auriporia aurulenta, Bolbitius variicolor, Bulgariella pulla, Chaetosphaerella phaeostroma, Clitocybe subspadicea, Clitopilus passeckerianus, Cortinarius anomalus var. subcaligatus, C. fervidus, C. flexipes var. inolens, C. sylvae-norvegicae, Cudoniella tenuispora, Entoloma bisporigerum, E. olorinum, E. poliopus var. parvisporigerum, E. sericeoides, Galerina caulocystidiata, Gymnopilus josserandii, Hymenoscyphus subferrugineus, Hypholoma olivaceotinctum, Inocybe queletii, Laccaria altaica, Lactarius romagnesii, L. rostratus, Mycena epipterygia var. atroviscosa, M. epipterygia var. candida, M. polygramma f. candida, Octavianina lutea, O. mutabilis, Pachyella violaceonigra, Panaeolus papilionaceus var. capitatocystis, Phaeocollybia jennyae, Psathyrella almerensis, Pyrenopeziza inornata, Scutellinia torrentis, Tricholoma basirubens, Tricholomopsis flammula, and Vibrissea decolorans. For all new taxa, short descriptions based on the collected material have been provided.

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.

Microstoma protracta (Fr.) Kanouse is a strictly protected species in Poland, which is also present on the red list with the category R (rare). In Poland, there are five known localities for the species, including four historical sites discovered at the beginning of the twentieth century and one contemporary site discovered at the end of the twentieth century. In this paper, we present two new localities for M. protracta, discovered in April 2006 in Czeszewo (Wielkopolska Lowland, Jarocin Forest District) and in April 2017 in Krakow-Tyniec (Krakow-Częstochowa Upland, Myślenice Forest District). Sequences of the nuclear ribosomal DNA internal transcribed spacer regions of sporocarps from contemporary localities have been deposited in the GenBank database. This is the first record of the DNA barcode for this species. According to Criterion D of the IUCN recommendations, it has been suggested that M. protracta should be considered as a critically endangered species (CR: D) in Poland.

The paper presents 32 species of macrofungi new to the Kampinos National Park, found during the studies on fire-damaged areas after the forest fires in 2015. Three species new to Poland were described and illustrated (Calycellina leucella, Exobasidium juelianum, and Gymnopilus decipiens). Four species from Polish red list of macrofungi have been recorded in the Kampinos National Park for the first time: Botryobasidium vagum (R), Geastrum coronatum (V), Helicogloea farinacea (E), Inonotus cuticularis (R). During the current studies 17 pyrophilous species new to the Kampinos National Park were found.

The paper presents a list of 19 coprinoid fungi, found in Poland, which have not been reported earlier from this area: Coprinellus bisporiger, C. dilectus, C. heterothrix, C. radicellus, Coprinopsis annulopora, C. bellulus, C. candidolanata, C. cinereofloccosa, C. coniophora, C. goudensis, C. idae, C. iocularis, C. krieglsteineri, C. pachyderma, C. phlyctidospora, C. rugosobispora, C. scobicola, C. spilospora, Coprinus palmeranus. Illustrations and short descriptions of the species, based on the specimens examined and literature data, are given.

The aim of this study was to describe the species composition of macrofungi in a manorial park in Turew and to evaluate thc importance of the park as a refuge habitat. The study carried out in 1997-1999 resulted in 177 taxa (Basidiomycetes - 84,7%, Ascomycetes - 15,3%). Among them 23 species were recognized to be protected or listed in the Polish Red List. It turned out that the manorial park in Turew is an important refuge area for many species of macrofungi occurring in agricultural landscape.

This study (conducted in western Poland) was aimed at recognizing the importance of straw heaps (SH) and manure heaps (MH) located in cultivated fields for fungal diversity in farmland. Fungi (24 species and 1 sterile form) were found in 19.1% of SH (N = 89) and 60.4% of MH (N = 169). The estimated species richness (Chao2) was 29.8 ± 12.7 and 18.1 ± 2.5 (SD), respectively. Species composition of fungal communities differed significantly between SH and MH. The studied ephemeral habitats contributed markedly to fungal diversity, both locally and on the national scale. The occurrence of fungi in SH was significantly positively related to heap size, while fungal species number in MH depended most strongly on the degree of shielding, linked with proximity of woods or shelterbelts. The results show that both the reduction of SH and MH numbers in farmlands (required by the Nitrates Directive) and landscape simplification are unfavorable for fungal diversity.

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 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.

The paper presents a list of fifty-five coprinoid fungi found in Poland, which have been not reported earlier from this area (28 species) or are known only from few localities. Four species new to Poland collected in Bieszczady Mts and mentioned, without descriptions, in earlier papers, were also included and described in this publication. For the species new to Poland, illustrations and short descriptions based on the specimens examined and literature data, are given.

The paper presents information about Xylaria oxyacanthae Tul. & C. Tul., a new species for Poland. The fungus was for the first time found in the mid-field shelterbelt near Turew village and in the city park in Kraków.

This article begins a four-part series, which presents the results of mycological research carried out in 2000-2007 in the agricultural landscape of the General Dezydery Chłapowski Landscape Park. This part includes description of the study area and field research methods, as well as a list and localities of 617 macrofungal taxa recorded in the Park. The next parts of this series will deal with: species that are rare, protected by law or recorded for the first time in Poland; the role of wooded patches for preservation of fungal diversity in the agricultural landscape; and changes in species diversity and structure of fungal communities in forest communities under strong human pressure.

The paper presents a list of flora taxa of the cultivated fields of General D. Chłapowski Landscape Park as well as their general characterisation. The segetal flora of the researched area consists of 215 species. 22 of them are on the list of threatened segetal plants.

The paper presents 47 fungi species belonging to the genera Cystolepiota, Echinoderma, Lepiota, Leucoagaricus, Leucocoprinus, Macrolepiota and Melanophyllum, found in Poland, which have been not reported earlier from this area (18 species: Cystolepiota fumosifolia, C. moelleri, C. petasiformis, Echinoderma carinii, E. pseudoasperula, Lepiota angustispora, L. apatelia, L. cingulum, L. cortinarius var. audreae, L. cristata var. felinoides, L. forquignonii, L. rubella, Leucoagaricus cinerascenss, L. ionidicolor, L. sericifer var. sericellatus, Macrolepiota heimii, M. rhodosperma var. rhodosperma, M. venenata) or have been known only from a few localities. For the species new to Poland short descriptions, based on the specimens examined and literature data, are given and their micromorphological characters are illustrated.

The paper presents the last part of the results of the short-term inventory of fungi species in the Biebrza National Park and synthesises all the data gathered during two surveys, including the information published by other authors. The main body of research is focused on a survey of macrofungi identified with morphology-based methods. In case of some specimens molecular technics have been applied. In total 346 macrofungal taxa (21 belonging to ascomycetes and 325 to basidiomycetes) were found during the survey, including 186 species unobserved during the previous inventory in 2012. As a result of previous and ongoing studies, the current number of macrofungi recorded from the Biebrza National Park reached 508 species. Among them eight taxa are newly reported for Poland (Conocybe velutipes var. nitrophila, Entoloma caeruleum, E. plebejoides, Inocybe rennyi, I. vulpinella, Pholiota pityrodes, Pholiotina utricystidiata, and Tomentella pilosa). The next seven species (Bovista paludosa, Fistulina hepatica, Ganoderma lucidum, Geastrum schmidelii, Inonotus obliquus, Tulostoma kotlabae, and Xerocomus parasiticus) are protected by law and 95 species belong to red-listed species. The results of two intensive, but relatively short-term survey clearly indicate the Biebrza National Park as a hot spot of macrofungi and suggest the need to undertake extended and regular inventories also in other Polish national parks.
