Phylogenetic relationships in the genus Helvella were investigated using both LSU rDNA sequences and morphological features. The latter were coded and included in the analyses, resulting in better-supported clades. Helvella is monophyletic and Wynnella is its sister genus. Aporhynchous vs. pleurorhynchous asci are the synapomorphies for the 2 subgenera, Leucomelaenae and Helvella, which were confirmed as natural groups. Other recovered supported clades were section Leucomelaenae in the subgenus Leucomelaenae, and sections Elasticae, Helvella, and Lacunosae within the subgenus Helvella. Generic description, comments on taxonomically informative features, species complexes, and species that need typification are presented.
