Lichenomphalia aurantiaca is a species of agaricoid (mushroom-like) basidiolichen in the family Hygrophoraceae. It was first scientifically described as a new species in 1987 by the mycologists Scott Redhead and Thomas Wilhelmus Kuyper, who originally classified it in the genus Botrydina. After proposed transfers to the genera Phytoconis and Omphalina, it was reclassified in Lichenomphalia in 2002, as part of a restructuring of the core omphalinoid genera in the Agaricales. In terms of its conservation status, it has been assessed as an endangered species by the International Union for Conservation of Nature because of its extremely limited distribution and fragmented populations, restricted to high-elevation páramo in Colombia.
