Bacidia rosella is a crustose lichen in the family Ramalinaceae, assessed as Critically Endangered (CR). It grows on the smooth bark of ancient trees in old-growth woodland habitats with long ecological continuity. Its critically endangered status reflects extreme rarity and the near-total loss of suitable veteran tree habitats across its range.
