Thank you, but I'm not the only one who offers as necessary, and I think Monikieman's view is sound; we think of it as passing along some of the good wishes that have been sent to us Karma kind of sums it up nicely.
'No great abundance' kind of fits with what is generally described. If a tree has it though and survives to feed the fungus long enough, then it can be a big lump. I've been told that the outer crusty black stuff is the best for the tea, but the commercially sold fungus seems to be a mix.
Good amadou is truly excellent for spark catching though and there are plently of fomes around….just that it needs work to prepare it.
I quite like making the felty/leathery amadou, and it can be made from many of the bracket fungus.
