Morphology
Description – see Randlane & Saag (1998).
Typical characters. Thallus dorsiventral, upper surface greenish yellow, lower surface brown to almost black. Lobes rather wide (8–15 mm). Medulla pale yellow, K + deep yellow.
Chemistry
Contains usnic acid in the cortex; secalonic acids A or C in the medulla, occasionally several fatty acids and traces of endocrocin and fumarprotocetraric acid are also present.
Remarks
A beautiful and easily recognized lichen characterized by the brown or black underside and yellow medulla. If fertile, the nephromoid apothecia often very large (to 20 mm in diameter) and attractive.
Ecology and distribution
Distributed in China, Japan, Russia and South Korea (see Fig. 6 in Randlane & Saag 1998). In China it has been found in Jilin, Sichuan, Taiwan, and Yunnan provinces (Wei 1991); probably also occurs in Tibet although not yet recorded. Corticolous on coniferous and deciduous trees in forests at lower and medium altitudes (up to 3200 m).
