Waynea is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was established in 1990 by the Swedish lichenologist Roland Moberg and named after the Wayne family who helped organize his collecting trip to California, where he collected the type species. The tiny lichens in Waynea form patches made up of scale-like lobes less than half a millimetre across, with powdery cushions that help them spread without sexual reproduction. The genus contains six species found in Europe and North America, growing on tree bark in small patches that can coalesce into mats just a few millimetres wide.
