Abstract
During investigations into fungal diversity in the Tibetan Plateau, two Helvella collections were made. Morphological characteristics and phylogenetic analyses of combined ITS and LSU sequence data revealed one collection represents a distinct new species that is introduced as Helvella cystidiata. Helvella cystidiata is characterized by having loosely saddle-shaped pileus, greyish to grey brown hymenium, lacunose stipe and inflated ectal excipulum cells. Furthermore, a known species Helvella lacunosa is reported in Tibetan Plateau. Detailed descriptions, illustrations and a phylogenetic tree to show the placement of two taxa are provided.
