The small bumps on enoki mushrooms are safe to eat if they are naturally occurring gill ridges or unopened mushroom buds. However, if the bumps are mold spots, slimy growths, or attached contaminants, they should not be consumed. Careful inspection is recommended before consumption to avoid ingesting harmful substances that may cause discomfort. If symptoms such as abdominal pain or diarrhea occur after eating, prompt medical attention is advised.

During growth, enoki mushrooms may develop dense small projections along the cap edges, or contain tender, unopened buds. These bumps are firm in texture, consistent in color with the mushroom body, and have no unusual odor. They represent a normal growth form, are rich in nutrients, and are safe for consumption.

If the bumps appear as white fuzzy patches, black spots, or are accompanied by a slippery texture and sour, rotten smell, this indicates the enoki mushrooms have spoiled and may harbor mold toxins. Consuming them can irritate the gastrointestinal tract and even damage liver function. Any enoki mushrooms with such abnormal growths should be discarded immediately.

When selecting enoki mushrooms, choose specimens with plump caps, free of abnormal bumps and odors. Rinse thoroughly under running water before eating to remove surface impurities and potential residues. For storage, seal and refrigerate promptly, and consume quickly to prevent spoilage and ensure food safety.
