I recently went on a fungus forage. It was just (for me) an excuse to go for a walk and talk with other humans, but it turned out to be an amazingly useful experience.
The others in the group turned out to be real enthusiasts, with a couple of experts who I would expect to be very expensive, if they were being hired to do shat they did for free, here.
One of the things which fascinated me most, was a throwaway remark asking me did I like Birch Polypore tea. I had never heard of it, and the lad extolled all the marvelous health properties, so when I got home, I looked it up.
It does indeed appear to be a really useful additive to any diet, so I have been collecting it at every opportunity, and I am drinking polypore tea daily, when I have it. I can say that I have noticed a real difference in my health, for the better. I cannot pass a plantation of birch now, without automatically looking for the brackets.
The way I make the tea is to chop up the polypores as small as I can, put about a cupful into a stock pot, add water and steep it overnight. Next day I bring it to the boil and simmer for about 45 minutes, then the pot sits on the stove top, or in the small fireside oven, where I draw off a cup two or three times a day.
I've also been letting Dolly Dumpling (the cockatoo) drink it with me, as he will demand to share everything I consume, and I think it is helping his health, too. Certainly he is not plucking as much as he used to. If I can scrabble up the money next year, I may take him for blood tests, to see is his aspergillosis is gone, or at least improved. I have high hopes for him.
If anyone finds birch polypore brackets, and doesn't want to use them for themselves, (unlikely, i know) I'll take em off your hands, will happily pay postage and even something for your trouble!
