    In the last decade, in addition to the study of the nutritional composition of mushrooms, the study of biologically active compounds occupies an important place. However, there is a need to find new and lesser known mushrooms species that have biological activity and potential for application in industrial conditions. The aim of this research is to determine the biological activity of aqueous and ethanolic extracts of Suillus granulatus wild mushroom through the determination of the content of total carbohydrates, total, α and β-glucans, as bioactive compounds, as well as determination of cytotoxic activity. Total carbohydrate content was determined using spectroscopic method, total, α and β-glucans were analysed using specific kits, and MTT test (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) was used for cytotoxic activity. IR-ATR (infrared spectroscopy - attenuated total refection) spectra of mushroom extracts were performed, too. Aqueous extracts had a higher content of total carbohydrates as well as glucan and had better cytotoxic activity against HeLa cells, while ethanolic extract of Suillus granulatus was characterized with better cytotoxic activity against HepG2 cells. Based on IR-ATR, the presence of different types of carbohydrates, glucans, proteins, phenols and flavonoids can be observed in aqueous and ethanolic, which is one of the reasons for the differences in their anticancer activity. The analysed extracts are an excellent basis for their further application in various products in order to obtain functional food with enriched biological value. Thus, using natural dietary supplements can significantly affect the positive changes in the health of consumers.

    This study presents the first report of three Hericium species in Kosovo: Hericiumn cirrhatum (Pers.) Nikol., H. coralloides (Scop.) Pers. and H. erinaceus (Bull.) Pers. These species were found in mixed deciduous and oak forests in the central-eastern part of the country.

    The mycobiota of Kosovo, especially fungi of the phylum Ascomycota, remains under-explored despite its ecological and biological importance. This study aims to assess the diversity and distribution of macrofungal species of the phylum Ascomycota in different ecosystems in Kosovo. Field work combined with laboratory analysis was conducted from 2017 to 2022, using standard mycological techniques for species identification. A total of 82 species have now been documented in Kosovo. Of these, 39 species have been previously reported in the scientific literature, and 43 species are new records, significantly enriching the knowledge of the diversity of fungi in Kosovo. Taxonomic analysis showed that these species belong to 56 genera, distributed in 34 families, 10 orders, six subclasses, five classes and one subphylum. The Helotiales and Pezizales orders had the highest diversity, with 12 and nine families, respectively. In contrast, the orders such as Xylariales and Hypocreales showed remarkable variation, while several other orders were represented by a single family. These results highlight the rich but under-explored diversity of Ascomycota in Kosovo and emphasise the importance of further research to support biodiversity conservation.

    CENANGIUM OLYMPIUM, COMB. NOV.

    New records of the cup-fungus Zeus olympius Minter & Diam. (Rhytismataceae, Ascomycota) are reported from the territory of Kosovo, and a new taxonomic combination for the species is proposed. Phylogenetic analyses were conducted using nrITS (Nuclear ribosomal internal transcribed spacer) sequences from dry material collected in Kosovo and Greece. Based on the new phylogenetic placement, where species morphologically identified as Zeus olympius are placed within a clade of the genus Cenangium, Cenangium olympium (Minter & Diam.) M. Karadelev, K. Rusevska, G. Wu & Zhu L. Yang is introduced as a comb. nov. for Zeus olympius.
