Morphology
Description – see Mattsson (1993).
Typical characters. Thallus dorsiventral, greenish yellow on both surfaces, with bright yellow marginal soredia and medulla of the same colour.
Chemistry
Contains usnic acid in the cortex; pinastric and vulpinic acids in the medulla; several other substances – zeorin and other triterpens – have also been detected by TLC (Mattsson 1993) but they have no taxonomic importance.
Remarks
The species is distinguished by the bright yellow marginal soredia and medulla, caused by the presence of pinastric and vulpinic acids.
Ecology and distribution
Widely distributed in arctic, boreal and mountainous regions of the northern hemisphere (see Figs 23 & 24 in Mattsson 1993). In Asia known from China (Neimongol, Jilin, Heilongjiang and Xizang provinces) (Wei 1991), Japan (Yoshimura 1979; Kurokawa 1991), Kazakhstan, Mongolia (Golubkova 1981) and Russia (Rassadina 1950). We have not seen any herbarium specimens of V. pinastri from Tibet but its occurrence there has been recorded in literature (Wei 1991). Grows preferably on coniferous (Juniperus, Larix, Picea, Pinus) but also on deciduous trees with poor bark (Betula), occasionally on lignum, rocks and soil.
