Gyromitra antarctica in Argentine Patagonia: database on distribution, ecology, and toxicity

Abstract

This dataset comprises two complementary components designed to support the taxonomic identification and toxicological assessment of Gyromitra specimens from southern South America. The first component consists of a molecular reference dataset including nuclear internal transcribed spacer (ITS), large subunit (LSU), and elongation factor-1 alpha (EF-1α) sequences, generated to enable robust phylogenetic identification. All analyzed sequences correspond to Gyromitra antarctica- (Patagonia-Argentina). The second component includes a specimen-based dataset derived from 82 fresh collections obtained along a Patagonian elevation gradient (300–800 m a.s.l.). This dataset integrates collection metadata (e.g., elevation, locality) with quantitative measurements of hydrazine content. Together, these datasets provide an integrated resource linking molecular identification, ecological variables, and toxin quantification, enabling the analysis of elevation-dependent variation in hydrazine content and supporting risk assessment associated with the consumption of wild Gyromitra.
