Variety description

10 August 2026

The variety was obtained as a result of hybridization to combine the qualities of two mycelium types: beige, providing the size and weight of the fruiting body, and pure white, forming a smooth cap. This strain became one of the first hybrids available for mass commercial cultivation.

Morphological characteristics include a transversely elliptical cap shape in longitudinal section and a trapezoidal stem shape. The gills are light brown, and the basidia are predominantly bisporous. The variety is characterized by stable yield indicators and product quality.
