Four alnicolous (Alnicola citrinella, A. suavis, Cortinarius alnetorum, and Gyrodon lividus), 2 cortinarioid (Cortinarius alnetorum and C. scutulatus), 3 entolomatoid (Entoloma conferendum, E. pallescens, and E. sordidulum), 1 hebelomatoid (Hebeloma aff. aestivale), and 2 clitocyboid (Clitocybe applanata and C. elegantula) fungi were collected, studied, illustrated, and first reported for the Turkish mycota from Trabzon. Cortinarius alnetorum was evaluated as both an alnicolous and cortinarioid species. Field trips were made in 2012 and 2013, and the microscopical studies were performed in January and February 2014. Identification of the collections was made according to morphological investigations and field characteristics.
