A new dark brown variety of Flammulina velutipes, referred to as ‘Asakchoco’, was bred by crossing two monokaryons isolated from the ‘Yeoreumhyang2ho’ and ‘Guemhyang2ho’ varieties. The pileus color of the new variety is dark brown and the stipe color is ivory, with uniformity from the upper section to the base. In addition, the primordia formation is uniform compared to that of the control, and the advantage of this is that the pileus does not become deformed after the primordia formation. During bottle cultivation, the period necessary for mycelial growth was 40 d, for primordia formation was 8 d, and for fruiting body growth was 16 d. The total cultivation period was 64 d, which was 2 d shorter than that of the control. The pileus was smaller and thicker and the stipe diameter was the same, but the stipe length was longer than that of the control. The number of valid stipes per bottle was 441, 24% higher than that of the control (357), and the yield was 197 g, 19% higher than that of the control (166 g).
