February 13, 2014Shitake and other Mushrooms:Where can I find accurate and more detailed information on growing Shitake and or other Mushrooms? Plus, I will be having my 8 mature Oaks trimmed with Arborist supervision plus, two Oaks will be removed. These two trees may have Oak Wilt. (according to a tree trimming business owner) Can I or the Arborist supervisor on site at removal, ID this disease? After reading the Extension’s pages on Oak Wilt, I am not convinced but can see that these trees may have the disease, and it sounds like leaving tall stumps of these two trees would be a bad idea for growing Shitake Mushrooms, however is it possible to strip the bark, bowl them out on top for planters, and paint or use a deck Australian Timber Oil to help control the sap spread by bugs? Thank you,Steve Brink<personal data hidden>

Oak wilt is a vascular disease caused by the fungus Ceratocystis
fagacearum. The disease stops the flow of
nutrients and water from the roots to the leaves. It is a bad idea to leave
infected oak wilt stumps. If your
trees are infected the fungus spores will soon be found under the bark on Oak
wilt mats. Sap beetles carry the
fungus to newly inflicted wound on other oak trees. Your oak wilt infected tree
stumps may have root grafts to other oak trees on your land. The disease organisms
can spread through interconnected root systems from one tree to another. Most
new oak wilt infections are the result of the fungus moving from infected to
healthy oaks via grafted root systems. Trees as much as 50 feet apart may be
grafted together.
If you peel back layer of bark on symptomatic oak wilt branch you will find a brown streaking on wood. Look for small dark dots in the wood just under the bark.

Eagle Bluff Environmental Learning center in Lanesboro MN used to grow mushrooms. They may be a resource for mushroom growing. http://www.eagle-bluff.org/ http://www.eagle-bluff.org/top/projects/shiitake/
The MN Woodland Advisor Program had a class a few years ago called Nontimber Forest Products that covered mushroom growing. I was unable to find if this class will be offered this year.
They are many extension sites for growing mushrooms. http://www.uky.edu/Ag/CCD/introsheets/mushrooms.pdf http://www.aces.edu/pubs/docs/U/UNP-0027/UNP-0027.pdf http://www.uky.edu/Ag/Forestry/extension/pub/pdf/90b63ee0eb423e6e316016b26a58ffd<personal data hidden>.pdf http://www.aces.edu/pubs/docs/U/UNP-0025/UNP-0025.pdf
