TIL, Crimini and Portabella mushrooms contain high levels of vitamin D. Even more if they are left to sit in the sun for a bit. Other strains contain vitamin d, but these are particularly high. Paul Stamets did tests on 1 year old dried, stored mushrooms that had been exposed to ultraviolet light when picked, and found they still contained significant mounts of vitamin D2.

i think its interesting that an organism that appears at the end of summer as the rains appear, provides a stable storage medium for bioavailable vitamin D as the amount of sunlight diminishes.

It's fascinating how much of late-summer through autumn is geared toward biological vitamin D production and storage. High carb and high fat food become readily available through tree mast and cereal harvests, game and livestock are the fattiest they will be all year. High carb, high fat diets make humans store fat. Vitamin D is stored in our fat. I'm totally not surprised that there are mushrooms that can store vitamin D when dried. Because why wouldn't God give us yet another gift.
