A new finding of Megalospora porphyritis, previously known only from North America and Japan was registered on Sakhalin and Kuriles, Far East of Russia. The taxon is considered as a good example of an American/Asian disjunction most likely related to geological events in the Tertiary. Illustrations of lichen’s morphological features and a map of finding points are provided.


Ежкин А.К. Megalospora porphyritis (Tuck.) R.C. Harris, новый вид для России. Вид Megalospora porphyritis, известный с Северной Америки и Японии, был впервые обнаружен на Сахалине и Курильских островах на Дальнем Востоке России. Таксон может рассматриваться в качестве хорошего примера Американо-Азиатской дизъюнкции, вероятно возникшей в результате геологических процессов в третичном периоде. В статье представлены фотографии лишайника, а также карта с точками нахождения вида.

Keywords: rare species, disjunction, relict, broad-leaved forest, редкие виды, дизъюнкция, реликт, широколиственный лес
