Organic Reishi - China-Strain - Ganoderma lucidum - Pure Culture

Organic Reishi - China-Strain - Ganoderma lucidum - Pure Culture

Synonyms: Reishi (Jap. "Divine or Spiritual mushroom), Ling Zhi, Mannentake, Saiwai-take, Jong Si/ryongji, Sarunouchitake 

The Reishi China cultivation strain was primarily developed for cultivation on mycelium bags in the greenhouse. It is ideally suited for the production of antler-shaped fruiting bodies, known as the Antler Form. Throughout the entire cycle, the filter bag is kept closed. This almost eliminates yield loss due to contamination, although the harvest is slightly lower compared to cultivation in an open bag. 
This mushroom is called Ling Zhi in China and Reishi in Japan. The german name "Glänzender Lackporling" (Shiny Ganoderma) refers to the appearance of this typical tree fungus. Traditions trace back approximately 4000 years of history of this fascinating mushroom! In East Asia, Reishi is traditionally a symbol of health, physical and mental recovery, longevity, high sexual activity, wisdom and wealth.
Reishi is rich in micronutrients such as iron, magnesium, calcium, zinc, copper, manganese and germanium. Particularly valuable are the polysaccharides and triterpenes contained in Reishi, such as ganoderic, ganolucidic and lucidemic acids.
Ganoderma lucidum is a saprobe (secondary decomposer) that mainly colonises hardwoods such as oaks, beeches, alders or birches. It prefers warm oak or mixed oak forests, as well as beech forests or hardwood floodplains. However, it can also thrive on hedges, in parks and alongside roadsides if the appropriate conditions are present.

Pure culture is always made fresh on demand. Production time: 3 to 6 weeks.
This product is fresh produce and should be processed immediately after delivery.
If the product cannot be processed immediately, it can be stored in refrigeration at 4 ºC for a maximum of 2 weeks.
Please consider these timings when placing the order.

Suitable cultivation methods: 
wood logs, mushroom patch, spawn bags for indoor greenhouse

Suitable substrats: hardwood
Suitable woods: birch, beech, oak or alder
Outdoors: this strain produces fruiting bodies in late autumn.

You receive living, actively growing, axenic cell culture, entirely free of other strains or contaminating organisms, for further propagation. Our pure cultures are custom-made and produced freshly after ordering -  in a class 100 clean room environment on a solid nutrient medium (MEA) based on plant-derived raw materials. The pure culture needs around 2-3 weeks until its mature enough for shipping. The culture is supplied in special cell culture flasks (Filling volume: 15 ml culture medium, Growth area: 25 cm², Measurements: L x W x H = 79,7 x 42,6 x 26,53 mm) with breathable, hydrophobic membrane. This special design prevents introduction of contaminants and facilitates optimum gas exchange thanks to the high air flow rate of the membrane. With this packaging, the mushroom culture can withstand longer shipping distances and time without compromising quality or germination ability.

This product is intended for professional production of grain spawn to further propagate this strain of fungi. Working with pure cell culture requires detailed mushroom cultivation skills. For beginners we recommend starting with grain spawn or sawdust spawn.
