Taxonomy

The species was first scientifically described in 1936 by the Japanese lichenologist Masami Satô, who considered it as a variety of what was then known as Anaptychia dendritica.^[3] Syo Kurokawa promoted it to full species status in 1962.^[4] It was transferred to the newly circumscribed genus Polyblastidium in 2015 by Klaus Kalb.^[5]
