Gyromitra antarctica Toxin Levels Across a Patagonian Elevation Gradient

82 fresh mushroom samples of Gyromitra antarctica were collected between 300 and 800 meters above sea level in Patagonia, with monomethylhydrazine content quantified for each. The dataset, authored by Romina B. Parada and last updated in April 2026, reveals a significant negative correlation between elevation and toxin concentration. It also includes results from two boiling treatments tested for toxin reduction.

Use Cases

• Modeling the relationship between elevation and toxin concentration based on the described negative correlation.
• Assessing the efficacy of culinary detoxification methods based on the boiling treatment results.
• Studying the phylogenetic identity of Southern Hemisphere Gyromitra species based on the molecular analysis data.

Strengths

• Includes 82 quantified samples, providing a basis for statistical analysis.
• Reports a strong, statistically significant correlation (ρ = -0.79, P < 0.001) between elevation and toxin level.
• Contains experimental results from two defined boiling treatments with precise toxin reduction percentages (97% and 94%).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The geographic scope is limited to a specific elevation gradient in Patagonia.
