Aim of the study: The purpose of this study was to determine the macrofungal diversity of Yuvacık Basin (Kocaeli) and its close environs.
Study area: The study area is situated in the east part of Marmara region within the boundaries of Kocaeli and Sakarya provinces of Turkey and it covers 25.759 hectares. The altitude range of region is 150-1610 meters. In addition, the region is in the transition zones of the three different phytogeographic regions containing the Euro-Siberian, the Mediterranean and Irano-Turanian
Material and Method: The fungal samples were collected from different localities of Yuvacık Basin and its close environs between 2015 and 2017. During field studies, macroscopic and ecological features of the samples were recorded and they were photographed in their natural habitats and then brought to the labratory. In the labaratory, macroscopic and microscopic characteristics of the samples were examined. After obtaining relevant macroscopic and microscopic data, fungal samples were identified. The identified samples were kept at the herbarium of Ankara University (ANK).
Main Results: As a result of field and laboratory studies, a total of 140 species belonging to 44 family and 14 order within the 2 divisions were listed. Among them, 13 species belonged to Ascomycota, 127 to Basidiomycota.
Research highlights: In this study, macrofungal diversity of Yuvacık Basin and its close environs were determined. One hundred and thirty-nine species were new for the region. Moreover, edible and poisonous macrofungi species were emphasized.
