Hymenoscyphus conscriptus & H. fucatus, newly recorded from Turkey

Abstract

Hymenoscyphus conscriptus and Hymenoscyphus fucatus are described as new records from Turkey based on morphological characters and DNA sequence data. Phylogenetic analyses of internal transcribed spacer nuclear ribosomal DNA sequences (nrITS) show that H. conscriptus and H. fucatus form well-supported clades. Hymenoscyphus conscriptus and H. fucatus cluster as a highly supported group, closely related to H. yui and H. serotinus, but represent independent species in the phylogenetic tree; the synonymy of H. conscriptus under H. calyculus is not supported phylogenetically. Detailed descriptions, illustrations, and discussions concerning morphologically similar and phylogenetically closely related species are provided for each species.
