Abstract

In the far northeast of Asia (Wrangel Island and the northernmost part of Kamchatka), two specimens of the previously unknown chemotype of Blastenia ammiospila were found. This chemotype is characterized by the presence of anthraquinones (7-chloroemodin and emodin) in the lichen thallus, whereas atranorin is absent there. Additionally, a lichenicolous specimen of B. ammiospila with small, 0.4–0.8 mm diam., orange-red to pale rusty-red apothecia was found in Yakutia growing on saxicolous thalli of Parmelia sp. and Umbilicaria deusta on granite outcrops. All findings are supported by molecular data (nrITS).
