Crab mushrooms thrive in a diverse range of environments, originating primarily in subtropical and temperate regions. They are typically found in open woodlands, grasslands, and near the bases of perennial plants, such as wild celery. The species favors sandy or loamy soils enriched with organic matter, which supports its growth. Geographic distribution extends across Southern Europe, Asia, and North America, where cultivation has become increasingly popular due to their culinary value. Commercial farming of crab mushrooms has gained traction, allowing for year-round availability. These mushrooms flourish in controlled environments, where humidity and temperature can be regulated, mimicking their natural habitat.

Harvesting crab mushrooms requires careful attention to ensure flavor and texture are preserved. They are typically harvested at maturity, characterized by a firm cap and sturdy stem. Hand-harvesting is common to minimize damage to the mushrooms and surrounding mycelium. After harvesting, the mushrooms are cleaned gently to remove any substrate or debris. Processing often involves washing and cutting, depending on their intended use. For preservation, crab mushrooms can be stored fresh in a refrigerator but have a limited shelf life. Alternatively, they can be dried or pickled to extend their usability. Dried mushrooms retain much of their flavor and can be rehydrated for use in various recipes. Proper handling and storage techniques are essential to ensuring that the quality of crab mushrooms is maintained, providing consumers with a delicious and nutritious product.
