Hypogymnia papilliformis
Species of lichen
Hypogymnia papilliformis is a rare species of foliose lichen in the family Parmeliaceae. Found in China and the Russian Far East, it was formally described as a new species in 2015 by Bruce McCune, Svetlana Tchabanenko, and Xin Li Wei. The type specimen was collected by the second author in the Lazovsky Nature Reserve at an altitude of 600 m (2,000 ft); here, in a mixed conifer–broadleaved forest, it was found growing on Korean pine. The lichen has also been recorded from a mixed forest in the mountains of Shaanxi Province in China, at an altitude of 1,500 m (4,900 ft). The specific epithet papilliformis alludes to the papillose texture of the upper thallus surface. Secondary compounds that occur in Hypogymnia papilliformis include atranorin, and physodic acid as major metabolites, and minor amounts of 2'-O-methylphysodic acid and vittatolic acid.
