Ezhkin, A. K. & Schumm, F. 2017. Heterodermia incana (Physciaceae), a new record for Russia – Herzogia 30: 504–508.
We report a new finding of Heterodermia incana, a rare lichen with an otherwise tropical distribution, from Sakhalin Island in the Russian Far East. It is the northernmost record for Heterodermia incana to date. We provide illustrations of its morphological features, an occurrence map and results of HPTLC.
