I added some research on vitamin D2 in mushrooms to the Bones, Vitamin D, and Calcium page at VeganHealth.org:

Vitamin D2 in UV Treated Mushrooms

Food manufacturers are now creating large amounts of vitamin D2 in mushrooms by exposing them to commercial ultraviolet light or direct sunlight (55, 56). The vitamin D is well-retained in the mushrooms over the course of the typical storage life of fresh mushrooms, up to two weeks (55, 57). This vitamin D is effective in improving vitamin D status and no different from a vitamin D2 supplement (2).
