''Lactarius rupestris'' is a species of mushroom in the Russulaceae family. Described as a new species in 2010, it is known only from the semi-arid region in the National Park of Catimbau of Brazil. The mushroom is characterized by a stout fruit body with a smooth and sticky orange cap up to in diameter. The gills on the underside of the cap are closely spaced and frequently anastomosed. The stem is long by thick. The mushrooms exude a sparse cream-colored latex when cut or injured. ==Discovery and classification== The species was found in the Brazilian semi-arid region in the National Park of Catimbau, in July 2007. It was described as new to science in a 2010 ''Mycotaxon'' publication by Felipe Wartchow of the Universidade Federal de Pernambuco. ''L. rupestris'' is one of 19 species of ''Lactarius'' known from Brazil. The epithet ''rupestris'' refers to the ''campos rupestres'' montane savanna—the ecoregion where the type species was collected.〔 The authors note that the fungus does not readily fit into any of the infrageneric (i.e., below the level of genus) classification schemes outlined by previous authorities. For example, although ''L. rupestris'' has several characteristics that make the section ''Edules'' proposed by Annemieke Verbeken a somewhat close match,〔〔 the taxon cannot be included because the surface of its cap is neither sufficiently areolate (cracked) nor dry enough, and its spores are excessively ornamented in comparison.〔
