Gassy Webcap

The Gassy Webcap (Cortinarius traganus) is a distinctive and intriguing mushroom species belonging to the large and diverse family Cortinariaceae. Known for its striking appearance and highly unusual scent, this fungus is a key player in coniferous forest ecosystems across the Northern Hemisphere. It is easily recognized by its initial pale lilac to silvery-violet color, which beautifully carpets forest floors, though it quickly shifts to a dull yellowish-brown as it matures. What truly sets this species apart, however, is its notorious odor. The mushroom emits a powerful, unpleasant chemical aroma often described as resembling acetylene gas, goat sweat, or rotting pears. This pungent scent acts as a natural deterrent against many woodland herbivores. Beneath its lilac skin, the inner flesh of the Gassy Webcap is a surprising saffron-yellow or rusty-orange, creating a vivid contrast for foragers who cut it open. While visually captivating, this mushroom is inedible and mildly toxic, causing gastrointestinal distress if consumed. It forms vital ectomycorrhizal partnerships with evergreen trees, assisting them in nutrient absorption.

Hábitat: Found in coniferous and mixed forests, particularly under spruce and pine trees, on acidic soils.
