I would like to nominate my photo of (what i think is) Sarcosoma latahensis if only because there appears to be no photographs of this species on the internets. http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=17061 The photo in the link is a cropped version of a larger photo. If necessary, I can send you the whole photo and you can edit it as you please.
I suggest you send this to George Baron, at the University of Guelph. I use his excellent book for mushroom identification in the field. I met him several years ago at the U of G. Your photos are excellent, almost unreal. Here is the URL: http://www.uoguelph.ca/~gbarron/index.htm Durgan.
