Liverworts are rather rudimentary plants, potentially some of the earliest true plants still in existence. In thallose liverworts, the plant body (thallus) consists of flattened masses of cells that look leafy but show little differentiation into different cell types. Maybe it's a product of my google-fu but the only Liverwort I can bring up similar to this plant is the Crescent Cupped Liverwort or Lunularia cruciata.
I suspect the small cup shaped leaves, or more properly thallus, are a type of gemma cup which is basically a modified bud structure designed to detach from the host plant to allow for new plants to grow! Liverworts are interesting in that they are similar to "higher body" plants but lack some key features that prevent them from becoming anything more than a footnote. That's assuming you even take note of them before putting your foot down.
I am completely stumped when it comes to identifying this plant. Honestly, it reminds me a bit of a cross between a venus fly trap and a pitcher plant. It looks predatory in a way, with its tiny cups pointed skyward, and several slick looking large spores in the center. I doubt it is a predator plant, but maybe it attracts flies to it that way in the hopes that they dislodge the spores of the Liverwort in order to help it reproduce. For reference, I live above the arctic circle in Nunavut, Canada. Hope that narrows down any biologist help.
