Hen of the woods is such great eating! I second your wish.
Berkeley's are dramatic and usually large (biggest I've seen was 50 lbs and filled a

This is the time of year for berkeleys. Hens are more of a fall emerger.
One of the bondarzewia has some research showing specific activity against types of leukemia, but I must not have created a reference for that source. If I find the source Ill try to remember to come back and post it.
