Some Edible Mushrooms of Kop Mountain (Erzurum-Bayburt) A R T I C L E I N F O A B S T R A C TThe present research was conducted on macrofungi collected from Kop Mountain (Erzurum-Bayburt) between the years of 2010 and 2011. The colorful photographs of macrofungi in the natural habitat were taken and their morphological and ecological features were determined and the information on macrofungi given by local people was recorded. According to the field and laboratory studies; 44 edible macrofungi taxa belonging to 14 families and 5 ordos located in Pezizomycetes and Agaricomycetes classes were identified.

Extract preparation: A fine dried mushroom powder (20 mesh) sample (5 g) was extracted with 80% of methanol (50 mL) for 24h at 4 0 C. The mixture was vortexed (Vortex, DAIHAN VM-10 Vortex, SK) for 5 min. Then, the extracts were filtered through Whatman No. 4 filter paper. MethodsDry matter: Dry matter content of dried mushroom was determined according to Association of Official Analytical Chemists methods [15]. The dry matter content was determined by drying in an oven at 105 °C for 24 h. Ferric antioxidant reducing power (FRAP):Methanolic extracts were mixed with 0.95 ml of ferric-TPTZ reagent (prepared by mixing 300 mM acetate buffer, p H 3.6, 10 mM TPTZ (2,4,6-tripyridyl-striazine, in 40 mM HCl and 20 mM FeCl 3 in the ratio 10:1:1), and absorbance was measured at 593 nm. FeSO 4 was used as a standard, and total antioxidant activity was expressed as μmol g AbstractThe methanolic extracts of dried wild edible mushroom were analyzed for antioxidant activity in different assays, namely, ferric antioxidant reducing power (FRAP), scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and total phenolic content. Among the twenty four mushroom extracts, the methanolic extracts from Leccinum scabrum showed the most potent radical scavenging activity showing 97.96%. The EC50 of Pleurotous dryinus and Lactarius piperatus methanolic extracts were 24.71 and 24.12 mg/ml, respectively. Total phenolics in the methanolic extracts were the highest in Boletus edulis. On the other hand, dry matter and ascorbic acid were determined in twenty four dried wild edible mushrooms. The amounts of ascorbic acid and total phenolic compounds found in the mushroom extracts were determined very low concentrations. Results from the PCA showed that principal components (PC) 1 and 2 described about 79.588 % of the total variation of sample. Therefore, edible mushrooms may have potential as natural antioxidants.

This study was carried out on wild edible macrofungi samples, collected within the boundaries of Gürpınar (Van) district between 2016 and 2017. As a result of necessary investigations related to macro and micromorphologies of the samples, 36 wild edible macrofungi species belonging to 11 families and 4 orders were determined. Eight of them belong to the phylum Ascomycota and 28 to Basidiomycota. Among the determined taxa Agaricus bisporus, A. campestris, A. urinascens, Pleurotus eryngii, P. ostreatus and P. populinus are collected and consumed by locals. Pleurotus eryngii is the only economically important macrofungi in the region.
