Xanthomendoza is a genus of small, bright orange foliose lichens with lecanorine apothecia. It is in the family Teloschistaceae.[1][2] The genus contains 17 species distributed in the Americas.[3] Members of the genus are commonly called sunburst lichens or orange lichens because of their bright orange color.[1]:130

Members Xanthomendoza were formerly classified in the genus Xanthoria, but Xanthomendoza members have rhizenes or scattered holdfasts, while Xanoria do not, and they have different conidia.[1]

Lichen spot tests on the upper cortex are K+ purple, KC-, C-, and P-.[1]
