Biatora ligni-mollis is a species of lichen in the family Ramalinaceae, first found in inland rainforests of British Columbia. This lichen grows exclusively on the soft, decaying wood of dead cedar and hemlock trees, forming thin white to pale cream crusts with abundant reddish-brown fruiting bodies. It gets its name from its preference for "soft wood" and glows brilliant white under ultraviolet light due to a lichen product called lobaric acid. Although first discovered in North American inland rainforests, it has since been discovered in several Western European countries including Belgium,
