Hypogymnia duplicata, the ticker-tape lichen, is a species of bark- and wood-dwelling foliose lichen in the family Parmeliaceae.[2] It is found in northwestern North America. It has narrow, ribbon-like lobes and typically lacks the powdery or finger-like outgrowths that many lichens use for vegetative spread. When conditions are suitable, it can form loose, draping tufts that hang from branches and trunks.
Erik Acharius published the name Parmelia duplicata in his 1803 work Methodus qua omnes detectos lichenes, treating it as distinct but linking it to the manuscript name Lichen duplicatus attributed to "D. Smith. The taxon was based on material reported from the western coast of boreal North America collected by Archibald Menzies. In his brief Latin diagnosis, Acharius described a loose, smooth, membranous thallus that was pale on the upper surface but black beneath, with linear lobes that were repeatedly divided and branched and tended to be inflated. He also remarked that apothecia (fruiting bodies) were unknown to him at the time, so his concept rested entirely on thallus form. In an additional note, he considered it allied to Parmelia colpodes (now Anzia colpodes), but said it differed in having looser, more inflated linear lobes.[3]
The Soviet lichenologist Kseniya Aleksandrovna Rassadina recombined the species in the genus Hypogymnia in 1967.[4]
