I am quite sure this is the right genus for both of these, but I don’t know the species. Tiny fruiting bodies.
I have never seen this in the flesh so to speak, but friends have. My wife and I are amazed at the things you find in your garden. Hope this link helps Nik. Cladonia - Wikipedia
Agree with you @Arlette that the first ones look like Cladonia macilenta, and the habitat excludes similar species. The others look a bit more like Cladonia chlorophaea group than C. pyxidata, but there might be more than one species there also. - There are a large number of Cladonas that have podetia with cups, so often hard to confirm ID w/o specimen in hand. ... also some Parmela/Xanthparmelia photobombers :-)
