Researchers successfully grew Podoscypha petalodes, a medicinal mushroom known as wine glass fungus, under controlled conditions for the first time. The best growth was achieved using a mixture of sawdust and tea waste at 28°C, which produced high yields in just 10 days. This breakthrough means that this therapeutic fungus, which has antiviral and anti-cancer properties, can now be cultivated year-round commercially instead of relying on rare wild specimens.
