Opis:
Mycological data published in the years 2012−2017 in six papers on the exhibitions of fungi of the Białowieża Forest (NE Poland) was analysed to demonstrate that incidental, few days long field studies in that region may provide interesting and valuable data on fungal diversity and richness. The discussed papers, in addition to the lists of species presented, include information on some interesting taxa collected during the preparation of the exhibitions. This data complements the knowledge on the fungal biota of the Białowieża Forest and is documented by the herbarium specimens. There are 865 macrofungal taxa (72 of Ascomycota and 793 of Basidiomycota) mentioned in these papers. Almost half of them (421 taxa) were particularly valuable fungi, with 239 being new for the Białowieża Forest, i.e. they had not been reported from this area earlier. 75 taxa found during the field work preceding the exhibitions had not been found in Poland previously (e.g. Chromosera cyanophylla, Clitocybe collina, Cortinarius talimultiformis, Cystoderma subvinaceum). Moreover, 67 taxa have not been so far reported from other localities in Poland (e.g. Amylocystis lapponica, Pycnoporellus alboluteus and Steccherinum tenuispinum). 15 fungal species collected before the exhibitions are protected in Poland, 6 of them are strictly protected. 185 red−listed fungi were also found, among them 1 species with Ex (extinct) category (Scytinostroma galactinum) and 61 with E (endangered) category (e.g. Pholiota squarrosoides, Punctularia strigosozonata, Rigidoporus crocatus). An analysis of the published data indicates that even short−term, incidental studies may provide important and valuable data on the fungi of the Białowieża Forest and that the potential richness of its mycobiota is much higher than previously recognised and estimated. Presented results confirm the need for further basic research on the biodiversity of macrofungal biota of the Białowieża Forest. It should involve application of new research methods, participation of taxonomists specializing in specific fungal groups, identification of threats and establishing of a conservation program and population monitoring of the most valuable species in this area.

Opis:
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.

Opis:
A variety of cultivated mushrooms in Northeast India are well known for their taste, nutritional and medicinal benefits. Many wild-growing mushrooms are also consumed due to their exotic flavours and tastes; however, the scientific exploration of their nutritional and bioactive properties is still negligible. In the present study, the 32 wild edible mushroom samples of 11 species collected from different parts of Northeast India were evaluated for their proximate composition, mineral and vitamin (ascorbic acid and riboflavin) contents, antioxidant and antihaemolytic activity, and profiles of organic and phenolic acids. Lentinus sajor-caju and Lentinus squarrosulus had the highest carbohydrate content (49.80 g/100 g dry weight (d.w.) and 46.36 g/100 g d.w., respectively), crude protein content (20.72 g/100 g d.w. and 20.54 g/100 g d.w., respectively) and a considerable content of minerals. The highest fat content was determined in Lentinus velutinus (7.17 g/100 g d.w.). Among the minerals, potassium was found as the most abundant in all the samples. The extracts of L. sajor-caju, L. squarrosulus, and Pleurotus pulmonarius were characterized by the highest antioxidant activity, while these of L. sajor-caju, Pleurotus ostreatus, P. pulmonarius and Agaricus bisporus showed the highest antihaemolytic potential. The HPLC analysis allowed determining the high contents of ascorbic acid and a few organic and phenolic acids such as lactic acid, gallic acid, 3,4-dihydroxybenzoic acid and trans-cinnamic acid in the tested mushrooms. Other compounds viz. citric acid, caffeic acid, riboflavin, vanillic acid, pyruvic acid, and p-coumaric acid were detected with variations. This study established the nutritional and health-promoting benefits of wild edible mushrooms of Northeast India region for consumption as functional foods in human diet.

Opis:
The European spruce bark beetle (Ips typographus) outbreak observed in the ‘Puszcza Białowieska’ Promotional Forest Complex since 2012 resulted in a total volume of 1.4 million m3 of dead trees in multiple spruce stands. The study aimed to assess the species composition of fungi occurring in spruce trunks at early stages of European spruce bark beetle attack. All the samples used in laboratory analyses were collected in 2016 and 2017 in Białowieża, Browsk, and Hajnówka forest districts. A total of 60 dying spruces selected at random were sampled providing 120 samples. Surface−sterilised samples were used in fungal isolations using malt extract agar medium. The resulting colonies were identified morphologically, additional molecular identification was carried out for representatives of morphotypes using ITS rDNA fragment. In addition to these analyses, the frequently occurring basidiomycete fungi on recently died spruce trees were identified based on the morphology of fruiting bodies. One of the most common symptoms observed on trunks of spruces at the early stages of dieback was the occurrence of sapstains starting from bark beetle galleries. In some trunks the stained wood sections were separated by rusty−red stripes. A total of 51 fungal species including 40 ascomycetes and 11 basidiomycetes were isolated from dying spruce trunks. The number of ascomycete species included 16 ophiostomatoid fungi (members of Ophiostomatales and Microascales). The frequently occurring species in this group were: Endoconidiophora polonica (=Ceratocystis polonica) (17.5%), Grosmannia penicillata (20.8%), Ophiostoma brunneolum (9.2%), O. piceae (5.8%) and O. abieticola (4.2%). Among other ascomycetes only three species were frequently isolated: Neonectria fuckeliana (15.0%), Clonostachys rosea (13.3%) and Cosmospora viridescens (9.2%). The rusty−red coloured areas harboured primarily Amylostereum areolatum and Stereum sanguinolentum. The most frequently detected basidiomycete fungus on trunks at the initial stages of dieback was Cylindrobasidium sp. (=Gloeocystidium ipidophilum), whereas Fomitopsis pinicola was the most frequent species on spruce trunks dead for some years, either standing or wind−snapped. We emphasise the potential role of the detected fungi in forest ecosystems of the Białowieża Forest, both as potential tree pathogens and decomposers of spruce debris remaining in the stand.

Opis:
Barwniki syntetyczne, ze względu na toksyczność i słabą podatność na biodegradację, należą do zanieczyszczeń niebezpiecznych i trudno usuwalnych. Jeszcze większe problemy nastręczają ich mieszaniny. Celem badań było przeanalizowanie efektywności usuwania mieszanin barwników z różnych klas z wykorzystaniem wybranych szczepów grzybów podstawkowych. Testowano mieszaniny dwuskładnikowe (zakres ich stężeń to 0,01-0,15 g/dm3) składające się z: antrachinonowego brylantowego błękitu remazolowego R (RBBR), azowej czerwieni Kongo (CK) i trójfenylometanowej zieleń brylantowej (ZB). Badano szczepy z gatunku Pleurotus ostreatus (szczepy BWPH i K4) i Polyporus picipes (RWP17). Usunięcie barwników analizowano w oparciu o wyznaczone długości fal odpowiadające najwyższej absorbancji. Zaskakująco wraz ze wzrostem stężenia mieszaniny 1 (CK+RBBR) obserwowano zwiększone usunięcie barwy przez grzybnię szczepów BWPH i K4. Ta sama mieszanina była dobrze usuwana przez szczep RWP17, a efektywność dekoloryzacji malała ze wzrostem stężenia (95 % dla 0,01 g/dm3; 75 % dla 0,15 g/dm3 mieszaniny). Usunięcie mieszaniny 2 (CK + ZB) było bardzo wysokie dla szczepów BWPH i K4. Wzrost jej stężenia powodował spadek efektywności procesu (100 % dla 0,01 g/dm3; 0 % dla 0,15 g/dm3 mieszaniny). Szczep RWP17 usuwał M2 w różnym stopniu - przy różnych długościach fali uzyskiwano odmienne wyniki. Badania potwierdziły, że usuwanie mieszanin barwników stanowi duże wyzwanie, a efektywność dekoloryzacji uzależniona jest od składu, stężenia usuwanej mieszaniny oraz zastosowanego szczepu.
Synthetic dyes, due to their toxicity and low biodegradability, belong to hazardous and hardly removable contaminants. Even bigger problems are caused by their mixtures. The aim of the study was to analyze the effectiveness of removing of mixtures of dyes from various classes using selected strains of Basidiomycota (Pleurotus ostreatus - BWPH and K4, Polyporus picipes - RWP17). Two-component mixtures consisting of anthraquinone remazol brilliant blue R (RBBR), azo Congo red and triphenylmethane brilliant green (concentration range of mixtures 0.01-0.15 g/dm3) were tested. Removal of dyes was analyzed at the wavelengths corresponding to the highest absorbance. Surprisingly with increasing concentration of mixture 1 (CK+RBBR), increased removal of colour by BWPH and K4 strains was observed. This mixture was well removed by the RWP17 strain and decolourisation efficiency decreased with increasing concentration (from 95 to 75 %). Removal of mixture 2 (CK+ZB) was very high for Pleurotus strains - increase in the concentration caused a decrease in the efficiency of the process (from 100 to 0 %). The RWP17 strain removed this mixture with different degrees at different wavelengths. Studies have confirmed that the removal of dye mixtures is very chellenging, and the process efficiency depends on the mixture composition, concentration and the strain used.
