The most amazing cancer curing medicinal mushroom. Reishi (japanese) or Ling Zhi (chinese) is known for centuries and was only reserved for emperors in old china. What a lovely to grow mushroom it is, really easy and strange when not exposed to enough oxygene.
I digged cultures in wet soil and had the most amazing and "perfectly looking" fruitbodies. But then again the "antler form" is amazing, too.
