        ‘Saeyan’is a mushroom variety with white-color, developed through single-spore crossing between the Auricularia cornea ‘Pungwoon’ (brown-colored) and the ‘JNM21235’ (white-colored). Using the RHS Color Chart, the superior strains with fruiting bodies were classified into eight colors, including light brown, dark brown, and white. Among these, the ‘Saeyan’ strain (JNM-MI-85) was selected as a new variety for its low wrinkle density, clean white color (NN155B), and reduced clustering of fruiting bodies. The ITS sequence analysis confirmed its classification as Auricularia cornea. It was named ‘Saeyan’, a pure Korean word meaning “new and white,” and filed for plant variety protection in 2018 (Application No. 2018-17). The variety was officially registered in 2021. ‘Saeyan’is characterized by its white fruiting body with an ear-shaped morphology. The optimal temperature range for mycelial growth is between 25°C and 30°C. Cultivation on sawdust bag substrate required approximately 38 days, with the primordia formation period being around 10 days. The total cultivation period was 112 days. The fruiting bodies exhibited a length of 55 mm, a width of 42 mm, and a thickness of approximately 0.92 mm. Mushroom formation can occur individually as single fruiting bodies or collectively as clustered formations. The mushroom yield was relatively high at 854 g/0.9 kg and demonstrated strong resistance to diseases.

        This study was conducted to obtain basic data on domestic wild Lanopila nipponica K specimens collected in Jeollanam-do from 2015 to 2017 to investigate the characteristics of fruit bodies and analyze their nutritional components. L. nipponica K. was mainly found near hills, such as in persimmon fields around hills, on mountain trails, and in bamboo fields. L. nipponica K. occurred from July to mid-October, especially after the rainy season or a typhoon, when the air humidity was increased. Rainfall occurred for 8–15 days during the 20 days before the collection date, and the average temperature was ≥ 23oC. The size of the fruit body was 12.3–28 cm, and the weight varied depending on the size; however, the fruit body was estimated to grow overnight, reaching the size observed at its discovery. As aging progressed, the surface of the fruit body cracked, and it turned dark after 6 days. Spores were lump-shaped when the surface was cut with a knife. When the soil on the surface of the site where the fruit body was located was scratched, a white thread-shaped mycelium expanded. At the time of collection, the flesh of the fruit body was white, but it turned brown and fluffy as maturity progressed. On the sixth day after the mushroom was generated, it produced a pungent odor and became friable, resembling a black cotton ball. The surface of the fruit body was white and had a circular or elliptical shape. Crude protein content tended to be high at 59% of the dry weight. The antioxidant activity, determined using the DPPH radical scavenging analysis method, was 167 vitamin C equivalents/100 g. The spores were brown, approximately 6 μm in size, with protrusions on their surface.

        팽이버섯 생육용 톱밥배지 내 질소함량(1.2~1.8%)과 생육단계 중 억제기 온도(2, 4, 6 ̊C)에 따른 자실체 특성과 저장기간별 저장 특성을 조사하였다. 톱밥배지의 이화학성 분석 결과 배지 내 질소함량에 따른 pH, 탄소함량 등은 차이를 보이지 않았다. 자실체 생육 특성은 배지내 질소함량이 높아질수록 수량은 증가하는 경향을 보였다. 억제기온도의 경우 질소함량에 따라 자실체 생육에 미치는 경향이 달랐는데 질소함량이 1.28%로 낮은 T1의 경우 억 제기온도에 따른 자실체생육에 차이가 없었고 질소함량 1.5% 이상 배지에서는 억제기 온도가 낮을수록 수량과 갓, 대의 길이가 증가하는 것으로 나타났다. 저장기간에 따른 중량감소율은 배지 내 질소함량에 따른 변화는 관찰되지 않았고, 억제기 온도 4 ̊C이하에서 1.50~1.93%로 6 ̊C보다 낮은 중량감소율을 보였다. 자실체 갓 색도는 저장 31일 후 배지 내 질소함량이 높은 T3에 억제기 온도 4 ̊C처리 에서 L값 84.81, ΔE값이 6.3으로 다른 처리구에 비해 갈변도가 적은 것으로 나타났고 관능평가 또한 저장 31일 후에도 5.2점을 받아 판매 가능한 수준의 품질을 유지하였다. 하지만, 전체적인 결과를 봤을 때 배지 내 질소함량과 억제기 온도에 따른 상관관계는 나타나지 않았으며, 두 조건이 복합적으로 팽이버섯의 품질과 저장성에 영향을 끼치는 것으로 보인다. 따라서, 톱밥배지 내 질소함량 및 생육단계별 온·습도 조건에 따른 팽이버섯의 생육과 저장성 특성에 관한 추가적인 연구가 필요할 것으로 판단된다.
