The needle like spores, although few and far between, are within the fruiting bodies.
This lichen grows on a rock. Cuz it’s awesome, lichens can also grow on metal structures, they’re coming for us. Lichen grow on a variety of substrate, they don’t really care and people can use them as decoration in terrariums and things almost like a moss. It’s hard to believe they can receive any nutrients from these sorts of substrates, but probably due to their close relationship with algae they can mange.
