Amanita vidua: A new record for Turkish Amanita Section Phalloideae based on morphological and molecular data

Abstract

In the present study, fungal specimens collected from Yeşildere village in Uşak province, Türkiye were evaluated. The specimens underwent detailed examination through both mor-phological and DNA (nrITS rDNA region and TEF1a gene) sequence-based phylogenetic analysis. Based on the evaluation of micro- and macromorphological characteristics, and phylogenetic analyses, the specimen was identified as A. vidua Gasch, G. Moreno & P.-A. Moreau. This identification marks A. vidua as a new record for the Turkish Amanita section Phalloideae. The study described this newly recorded species, including specific details such as its location, habitat observations, geographical coordinates, collection date, and pho-tographs showcasing its macro and micromorphological features. Additionally, it also in-cludes illustrations of some microscopic structures of the species. The study is further en-riched with SEM images, offering a detailed view of the species characteristics, and the findings are briefly discussed.
