Morpho-molecular characterization and epitypification of Annulatascus velatisporus

The holotype of Annulatascus velatisporus, the type species of the genus Annulatascus, which is the core species of Annulatascaceae (Annulatascales) is in poor condition as herbarium material has few ascomata and molecular data could not be generated. Therefore, an epitype is herein designated for the precise delineation of this taxon. A morphological description and DNA characterization are provided for the epitype, obtained from the holotype location. Therefore, this specimen merits use as an interpretive type (epitype) for the holotype of A. velatisporus collected from submerged wood in a river, at Milaa Milaa Falls, north Queensland.
