Lepista nuda, also known as the wood blewit mushroom, is a litter-dwelling mushroom that typically grows on the ground in nutrient-rich areas. It is commonly found in fairy rings under oak and beech trees, among fallen leaves, and sometimes under certain conifers. This mushroom is distinguished by its characteristic, slightly anise-like scent.
❄️ Storage of the mycelium: 1 month in the refrigerator.

🌱 Growing conditions
Outdoor cultivation is recommended for the wood blewit mushroom, although it can also be grown indoors on a bedding substrate (composted manure + a layer of mulch). Outdoors, it can be sown in mulch beds around areas of compost, prunings, or various organic debris. The colonized substrate should be covered with a thin layer of soil or potting mix to retain moisture. Commercial growing conditions are similar to those for button mushrooms. Outdoor planting should preferably take place in the spring for fruiting the fall, during the first frosts.
🛠️ Growing media
The wood blewit mushroom thrives on well-aerated substrates such as composted manure, compost, and leaf litter. Like other layer fungi, its mycelium is stimulated by the presence of certain specific bacteria found in the soil.
