After consuming a meal composed of equal parts of Suillus piperatus and Armillariella mellea, two middle-aged men experienced symptoms resembling an allergic reaction, with itching being the main complaint. The report suggests that although Armillariella mellea is generally considered edible when properly prepared, Suillus piperatus is not, and may have caused the reaction. The case adds to the understanding of pseudoallergic syndromes caused by mushrooms, especially involving species with disputed edibility.
