Variety description

10 August 2026

The strain is intended for industrial and amateur cultivation. It is characterized by low maintenance regarding growing conditions: a minor temperature fluctuation is sufficient to transition from incubation to fruiting.

The fruit bodies are characterized by round or oval-shaped caps. The structure of the mushrooms is dense and firm, which ensures good transportability of the produce.

The strain is high-yielding. Precise data on its breeding pedigree are absent in open sources; it is classified as a hybrid isolate.
