I don't know if you are interested in other uses for mushrooms but I still dry a giant puffball by hanging in an onion net in the shed where it is cool and dry it goes very fibrous as it makes millions of spores. This fibre is pulled out and used on an open wound or cut instead of lint. Its healing qualities are amazing and it is easier to change the dressing than lint as it doesn't stick.
I first got to use this method in 1960 when I worked as a butcher but I used to hear tell of wagonners using it on flesh wounds on horses cheaper and more effective than vets.
'If mushrooms see the light' is an article in the Los Angeles Times that indicates that mushrooms exposed to daylight (all wild mushrooms) produce large amounts of vitamin D2.
