These were from a poplar that lost a huge limb last winter. It was probably a good six inches in diameter at it's largest and probably at least fifteen feet long.
I cut it up into about five three foot pieces. It took about a little over an hour to inoculate all of the logs.
The oyster mushrooms are not as tasty as the shiitake mushrooms are, at least they aren't to me. They are a little harder to clean as well. Still they are pretty good sauteed in butter.
