The standard does much to improve merchantable quality, distribution efficiency and fair dealings by shipping of the standard agricultural products. Mushrooms notified as the standard are five items; Pleurotus ostreatus, Pleurotus eryngii, Flammulina velutipes, Agaricus bisporus and Ganoderma lucidum. But many farmers are suffering from a strict standards. So these standard is required modification to fit farmhouse situations. This study was carried out to investigate mushroom quality of farm shipping and quality change during preservation at various treatment. Flammulina velutipes and Agaricus bisporus preserved at different temperature( 4℃, 10℃, 20℃) to investigate quality changes. Pileus diameters of Flammulina velutipes was 67% of first grade and 33% of second grade at the early stage. After two weeks, pileus diameters was not signigicant changes; 50% of first grade, 50% of second grade at 4℃ and 50% of second grade, 50% of third grade at 10℃. Although there were no significant changes of diameter at 20℃, most of the fruit bodies were decayed. In case of Agaricus bisporus, pileus diameter was 15% of first grade, 81% of second grade and 4% of third grade at the early stage. The more storage period longed, the more the color of the fruit body was browned. But pileus diameters was not signigicant changes. Hardness and chromaticity of these mushroom was declined as time passed. Now we are carrying out more research on some mushroom’s standards for improve consumer confidence.
