- Here is an odd thought - during the First World War, the supply of ink was very low in Germany and many started to use members of the old genus coprinus (Shaggy manes etc.) for ink. It is fun to let Shaggy manes turn to ink so children may use "mushrooms" for ink. I wonder if a similar practice was ever done in the ANE? Are there mushrooms or toadstools in the area which will turn into a black liquid?
