Variety description
10 August 2026
The strain is characterized by a short production cycle of 60 to 75 days. Fruit bodies have a dense and fleshy consistency, with cap diameters ranging from 5 to 15 cm. Cap color depends on growing conditions: they acquire a gray hue at low temperatures, and become creamy-beige at high temperatures.
The productivity of the strain is 16–30% of the wet substrate weight. Fruiting occurs within a temperature range of 8 to 20°C and does not require a pronounced cold shock. The strain is sensitive to ventilation levels and carbon dioxide concentration in the cultivation room.
Due to their resilient texture, the fruit bodies withstand transportation well. The strain is characterized by moderate spore production and relatively late spore maturation, which reduces the risk of allergic reactions during regular harvesting.
