The evernew stoves don't have a lid. These do fit a trangia too apparently.
Your pot sits on top and the flames come from the lower holes once it's bloomed, similar to a whitebox but works for smaller pots too. You can use a small trivet though if you like, they are £5 from backpackinglight.
I always burn dry, meths seals the lids on the burners and it stinks my mug out if stored inside.
