Lions mane mushrooms are prized for their unique texture and earthy flavor, making them a favorite for gourmet dishes. Because they have a dense, meaty structure, they can hold up well in storage compared to softer varieties. However, like all fungi, they are susceptible to moisture and decay over time. When stored correctly in the refrigerator, these majestic mushrooms remain culinary gems for about a week. Knowing how to spot the subtle changes from peak freshness to early spoilage ensures you only use the highest quality mushrooms for your next gourmet creation.

Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
