Citizen Science: Growing Mushrooms on Logs with Beech Bark Disease
While we've studied whether or not you can grow mushrooms on wood from certain diseased trees, there are still several diseases we have not tested. This citizen science study aims to examine if Beltane & West Wind Shiitake (Lentinula edodes) and Lion's Mane (Hericium erinaceus) mushrooms can be cultivated on American Beech (Fagus grandifolia) logs affected by Beech Bark Disease.
Beech Bark Disease is currently a major threat to American beech trees throughout eastern North America and continues to spread. The Beech scale insect (Cryptococcus fagisuga) was accidentally introduced to NA around 1890 and discovered to be killing trees in the 1930's in tandem with a certain fungus. When the common Beech scale infests a beech tree, it can become a biological vector of a fungal strain in the Neonectria sp., native to NA, and the beech tree will start to form cankers (localized areas of dead tissue). The cankers may girdle the tree, restricting flow of nutrients, which will physically weaken the tree, and eventually end in demise. We are testing Shiitake and Lion's Manes' ability to consume diseased wood.
This project focuses on agricultural zone 4b, where Kent & Lyn Black are testing the compatibility of twenty American Beech logs infected with Beech Bark Disease and their potential for mushroom cultivation. The logs were cut on April 19th, 2022, averaging in size of 40" length x 6" diameter, the logs were then inoculated on May 4th-5th, 2022, with the drill-and-fill method. Seven logs were inoculated with Beltane Shiitake, three with West Wind Shiitake, and ten with Lion's Mane sawdust spawn. The logs were stored for incubation on a 3" dunnage laid on the ground in a very sheltered, shaded area. Although the bark is compromised by the disease, which is typically not ideal for mushroom cultivation, no effort has been made to seal or remediate the affected zones.
In Progress - results expected near May of 2023.
- Logs started to show colonization on September 1st, 2022.
