Cloning Agarikon to save its Mycodiversity

One way of protecting the #biodiversity of #fungi – #mycodiversity– is to #clone a wild #specimen and get it into #culture.

Over many years we have built the largest collection of Agarikon (Fomitopsis officinalis = Larificomes officinalis) strains in the world. #Agarikon habitats are increasingly being lost as this #mushroom dwell primarily in the old growth forests of northwest North America, in sky islands in the #Alps of Austria-Slovenia-Italy and in northeastern Eurasia. As the forests are cut, unique strains of fungi, including Agarikon, are lost. Agarikon is now considered a threatened species in #Europe.

By preserving as many Agarikon strains as possible, we hope to test each one for their unique properties.

The first step is to find them. Pamela Kryskow, MD and I hiked deep into an old growth forest near a lake on a remote island in #BritishColumbia. Once we found a colony, we used a cork borer to excise a small piece of tissue and left the #conks to live.

The next step was to go into the #laboratory and #subculturefragments of this tissue into nutrient filled petri dishes. PTC

Then, after #cultures grew out, one or two are selected for further culturing into another #generation of dishes.

From one of these dishes, the best-looking #mycelium was then transferred into test tubes for long time storage.

With that last step, we have "banked" the strain once it grows out and then put into refrigeration for long term cold storage.

In this video, we show you how we do it.

For #teachers, #students, #remotelearners and the #DIYpeople out there, I hope you find this useful.
