A list of 79 species of macromycetes recorded in the Dendrological Park of the Warsaw Agricultural University in Warsaw between 1996 and 2005 is discussed in the paper

Suillus lakei (Murrill) A. H. Sm. & Thiers (Boletales, Basidiomycota) in Poland: new data

This study presents up-to-date data on the distribution of the Western Painted Suillus Suillus lakei in Poland. This alien species of fungus was first recorded in Poland in 2012, followed by a second recording in 2013. The third site, presented in this article, was discovered in 2016. A description of the newly discovered site and the basidiomata is given. All three sites of S. lakei are located on private properties overgrown with young Douglas fir. Two of the three recorded sites are located within the boundaries of the Wielkopolskie Province, and one in the Kujawsko-Pomorskie Province. Further expansion of this fungus in Poland is expected

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

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

Contribution to the knowledge of fungi of the Kampinos National Park (Poland) with particular emphasis on the species occurring in burnt places

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

Colorectal neuroendocrine neoplasms — management guidelines (recommended by the Polish Network of Neuroendocrine Tumours)

Nowotwory/guzy neuroendokrynne (NEN/NET) jelita grubego są rozpoznawane coraz częściej, szczególnie guzy odbytnicy. To zjawisko jest najprawdopodobniej związane z powszechnym wykonywaniem kolonoskopii przesiewowych. Coraz więcej przemawia za tym, że NEN odbytnicy i okrężnicy to dwie odrębne choroby. Nowotwory neuroendokrynne odbytnicy są najczęściej zmianami niewielkich roz­miarów, cechują się niskim lub umiarkowanym stopniem złośliwości histologicznej, dobrym rokowaniem i większość z nich kwalifikuje się do leczenia endoskopowego. Natomiast NEN okrężnicy to często nowotwory agresywne, niskozróżnicowane, o złej lub niepewnej prognozie, wymagające operacji. Zasady postępowania z tymi chorymi stale się zmieniają. Opierając się na najnowszym piśmiennictwie oraz ustaleniach wypracowanych na spotkaniu roboczym Polskiej Sieci Guzów Neuroendokrynnych (grudzień 2016 r.) w pracy uzupełniono i uaktualniono dane i wytyczne postępowania dotyczące NEN jelita grubego, opublikowane w Endokrynologii Polskiej 2013; 64: 494–504.Neuroendocrine neoplasms/tumours (NENs/NETs) of the large intestine are detected increasingly often, especially rectal tumours, which is probably associated with the widespread use of screening colonoscopy. There is a growing body of evidence supporting the thesis that the NENs of the rectum and the NENs of the colon are two different diseases. Rectal NENs are usually small lesions, of low to moderate histological malignancy, associated with good prognosis, and most may be treated endoscopically. NENs of the colon, however, are often aggressive, poorly differentiated, associated with a poor or uncer­tain prognosis, and require surgical treatment. The management guidelines regarding these groups of patients are constantly changing. On the basis of the recent literature data and conclusions reached by the working meeting of the Polish Network of Neuroendocrine Tumours (December 2016), this study completes and updates the data and management guidelines regarding colorectal NENs published in Endokrynologia Polska 2013; 64: 358–368.

Pancreatic neuroendocrine neoplasms — management guidelines (recommended by the Polish Network of Neuroendocrine Tumours)

W niniejszej publikacji przedstawiono zaktualizowane zalecenia dotyczące diagnostyczno-terapeutycznego postępowania w nowo­tworach neuroendokrynnych trzustki (PNEN) zaproponowane przez Polską Sieć Guzów Neuroendokrynnych. Zawierają one nowe dane uzyskane w latach 2013–2016, które albo potwierdziły wcześniejsze wytyczne, albo doprowadziły do zmian lub utworzenia dodatkowych zaleceń. W diagnostyce duże znaczenie mają badania biochemiczne, obrazowe (anatomiczne i czynnościowe), jak również rozpoznanie histopatologiczne, które determinuje postępowanie z chorymi na PNEN i musi być potwierdzone badaniem immunohistochemicznym. Terapia PNEN wymaga współpracy wielodyscyplinarnej grupy doświadczonych specjalistów zajmujących się nowotworami neuroendokrynnymi. Leczenie chirurgiczne jest podstawową metodą postępowania w wielu przypadkach. Dalsza terapia wymaga wielokierunkowego działania, dlatego omówiono zasady bioterapii, leczenia radioizotopowego, celowanego leczenia molekularnego oraz chemioterapii.This article presents updated diagnostic and therapeutic guidelines for the management of pancreatic neuroendocrine tumours (PNEN), proposed by the Polish Network of Neuroendocrine Tumours. The guidelines contain new data received in the years 2013–2016, which confirm previous recommendations, and have led to modification of previous guidelines or have resulted in the formulation of new guidelines. Biochemical and imaging (anatomical and functional) tests are of great importance in diagnostics, as well as histopathological diagnosis to determine the management of PNEN patients, but they must be confirmed by an immunohistochemical examination. PNEN therapy requires collaboration among the members a multidisciplinary team of specialists experienced in the management of these neoplasms. Surgery is the basic form of treatment in many cases. Further therapy requires a multidirectional procedure; therefore, the rules of biotherapy, peptide receptor radionuclide therapy, molecular targeted therapy, and chemotherapy are discussed
