Have now separated photos.

As one key puts it

some species are cupped “right from the start”. So the odds are these are different, not just different ages of the same species. If it’s going to be cupped it won’t wait around! And it is not at all uncommon to find multiple species of Cladonia growing intermixed. Pretty exasperating, sometimes, actually. :)

Maybe I should separate the two?

I thought the first seemed immature, then found the second within 2 feet of it. They really don’t look alike thought, do they?

Looks like two species

The cups look like C. chlorophaea group. They look too broad to merely be cupped forms of the thing in the second photo. The second could be C. coniocraea or C. ochrochlora, or maybe even C. umbricola. That group – the subulate gray Cladonia – is really hard, even with the help of chemistry as a crutch.
