Two new species of Inocybe (Inocybaceae: Agaricomycetes) from Türkiye based on morphological characteristics and phylogenetic evidence.

During a survey of agarics in the Mediterranean region of southwestern Türkiye, some noteworthy mushrooms were collected. Among the specimens, we discovered two new species of Inocybe, which are proposed and illustrated in this study as Inocybe pseudogeophylla and I. succinea. Molecular phylogenetic analyses based on a nuc rDNA ITS1-5.8S-ITS2 (ITS) and partial 28S rDNA (LSU) dataset reveal that these species belong to the Inocybe geophylla group. The sequences of the new species form two independent lineages and differ from the known species of Inocybe by a unique combination of morphological characteristics. Detailed macroand micromorphological features, colour photographs, habitat, and distribution data for the two novel species are provided, and their relationships with closely related species are discussed.
