The inventive variety of shiitake mushroom plant named ‘FFT-52’ is morphologically characterized by a greater pileus diameter and a greater pileus thickness. Further, ‘FFT-52’ ensures a higher crop yield and an easier harvesting operation because it can be easily harvested manually without the use of a harvesting device.
