<i>Nimisora</i> (<i>Lecanoraceae</i>, <i>Ascomycota</i>), a new genus for a common lecideoid epiphytic species from the central Iberian Peninsula

Abstract The new genus Nimisora Pérez-Ort., M. Svenss. &amp; J. C. Zamora is introduced to accommodate a puzzling lecideoid epiphyte common in the central Iberian Peninsula. characterized by following combination of characters: apothecia, excipulum composed sparingly branched radiating hyphae with narrow lumina, thick walls and swollen terminal cells, presence brown K+ olivaceous green pigment epihymenium, an ascus tip similar Bacidia -type, simple ellipsoid ascospores. Molecular analyses based on nrITS, nrLSU mtSSU sequences unequivocally place within Lecanoraceae ; however, its phylogenetic affinities other genera family remain largely unresolved. Comparisons morphologically closest are provided. single species genus, iberica Turégano, sp. nov., also described as science.
