Morphology
Description – see Randlane & Saag (1998).
Typical characters. Thallus foliose, characteristically rugose (in a somewhat concentric pattern), intense green to lemon yellow on the upper surface and brown on lower surface. Marginal but juvenile apothecia often present.
Chemistry
Contains usnic acid in the cortex; lichesterinic and protolichesterinic acids in the medulla; fumarprotocetraric acid (Huneck et al. 1984), stictic and constictic acids (personal communication from T. Ahti) have also been detected in some specimens.
Remarks
Ecology and distribution
Distributed in China [Hebei, Jilin (Wei 1991), Shaanxi and Sichuan provinces], Mongolia and Russia (see Fig. 2 in Randlane & Saag 1998). Not recorded from Tibet but highly probable there. The only epilithic representative in this group of yellow cetrarioid lichens. Grows over the rocks and boulders in shaded localities in montane forests at lower and medium altitudes (up to 3000 m).
