Pseudocyphellaria glabra is a species of corticolous (bark-dwelling), foliose lichen in the family Peltigeraceae. It has a pale-green upper thallus surface, a white medulla and white pseudocyphellae (tiny pores for gas exchange).

Distribution

Pseudocyphellaria glabra has a

subantarctic islands of New Zealand. Population genomic analyses suggest that lichens from these different locations are genetically distinct, but regular long-distance dispersal of spores during the Quaternary probably prevented the local populations from evolving into distinct species.[2]

Taxonomy

The lichen was first formally described in 1844 by Joseph Dalton Hooker and Thomas Taylor as a member of the genus Sticta. Their original report recorded occurrences from the Auckland Islands, Campbell Islands, Falkland Islands, Cape Horn, and Van Diemen's Land (modern-day Tasmania).[3] Carroll William Dodge transferred the taxon to the genus Pseudocyphellaria in 1948.[4] It has acquired many synonyms in its taxonomic history.[1]

Ecology

necrotic zone measuring 1.5–8.5 mm (0.06–0.33 in) in diameter, and usually located on the margins of the host thallus.[5]
