I also saw some more Fluted Black Helvella and then came upon a new one for me, this Helvella with a tan cap. I'm pretty sure it's not a black one with an inordinately light cap (I have seen grey ones before). Will have to do some more research to see if I can get the exact species. All told I saw about a dozen of them.
This sunset featured one piece of interesting optical phenomen: a sun pillar. As is so often the case with sunsets, photos don't reveal all that the eye does, so my pictures of the sun pillar are too faint to be of much use. Instead I'll link to this photo from Wikipedia:
