Looking like something has chewed it up and spat it out, the white saddle mushroom is one of those fungi that look otherworldly strange to me. The whole fruit body is actually a highly folded thin sheet, like mother nature's origami. You can spot these little oddities in the leaf litter of Beech or Oak. I am reliably informed that some of the old books described white saddle as edible, but this was likely down to poor research, as they actually cause upset stomachs if ingested and may be carcinogenic. So enjoy spotting in the woods but do not forage!
