Xylaria rohrensis, a new species inhabiting nutshells of Juglans regia in Austria

AXylaria species growing on nutshells of Juglans regia is newly described as X. rohrensis. It belongs to the X. carpophila group for having cylindrical, mostly unbranched stromata with a sterile apex and inconspicuous perithecial mounds on the fertile part overlain with an outer layer split into stripes. Phylogenetic analyses based on alpha-ACT, RPB2, and beta-TUB placed X. rohrensis right next to X. reevesiae in a clade, to which X. oxyacanthae, X. palmicola, and X. putaminum also belonged.
