This study was based on three macromycete samples collected during field studies carried out to determine the macrofungal biodiversity of Of and camburnu districts of Trabzon province (Turkey). As a result of necessary investigations, Pluteus variabilicolor Babos (Pluteaceae), Coprinopsis urticicola (Berk. & Broome) Redhead, Vilgalys & Moncalvo (Psathyrellaceae) and Chroogomphus confusus Y.C. Li & Zhu L. Yang (Gomphidiaceae) were recorded from Turkey for the first time. Brief descriptions and photographs related to macro- and micromorphologies of the species are provided together with their localities, geographical positions, collection date and Genbank number related to genetic sequences.
