Resumen

LANDEROS, Fidel et al. Advances in the phylogeny of Helvella (Fungi: Ascomycota), inferred from nuclear ribosomal LSU sequences and morphological data. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.4, pp.856-871. ISSN 2007-8706.  http://dx.doi.org/10.1016/j.rmb.2015.09.005.

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.
