Venus and the Elves:
Venus is hot and humid, and even though it has a thick cloud layer, its proximity to the sun causes a large amount of UV radiation to pierce the clouds. To the human eye, Venus is mostly a dense swampy jungle of thick black mycelia. Descended from the altered fungi that helped terraform Venus in ancient days, the current ropy tree-like growths cover the majority of Venus’ surface. Although they usually form biomes that are some flavour of “hot, wet, and fungus-trees”, there are a variety of biomes ranging from wetlands and dense jungle, to swamp, moor, shallow sea, and massive river deltas.
