I don't know if this is "Orange Jelly" - to my extremely ignorant eye when it comes to Fungi, Lichen and Slime Mold ID, it looks rounder and smoother than other "Orange Jelly" specimens I've found. Also, to me, this looks more yellow than orange, so I'll simply call it a yellow jelly fungus. Seen in the Snakes Head Natural Area, north west of Calgary, on a botanizing trip three days ago. Thanks, Doug, for the useful information you posted below! Much appreciated!
