A 25-year analysis of Armillaria (honey mushroom) poisoning in Wisconsin

This study aimed to characterize the clinical presentation, management, and outcomes of suspected or confirmed Armillaria (honey mushroom) poisonings reported to the Wisconsin Poison Center over a 25-year period. The analysis identified 18 cases, predominantly affecting adults, with gastrointestinal symptoms being the most common outcome, and highlighted the challenges of misidentification with toxic mushroom species. The findings suggest that while Armillaria ingestion typically results in a self-limited gastrointestinal toxidrome, careful consideration of potential toxic look-alikes is essential for accurate diagnosis and management.
