Assessment Status Notes

Taxonomic notes

This taxon resembles Pseudephebe pubescens more than any known Bryoria sp., but a number of characters exclude that genus, such as the pseudocyphellae, the soralia and the presence of norstictic acid (see Brodo & Hawksworth 1977). The genus Nodobryoria Common & Brodo (Common & Brodo 1995) might be considered, due to the cortex type, but the cell walls of that genus lack lichenan (Common 1991).


Why suggested for a Global Red List Assessment?

Extremely rare, known only from three collections (the last in 1992) from a single locality, which is also the locality of other rare Falkland Island endemics (Carbonea hypopurpurea, Immersaria fuliginosa, Rimularia andreaeicola, Usnea austrocampestris).


Geographic range

Known only from Mt Maria, East Falkland


Population and Trends

Unknown

Population Trend:


Habitat and Ecology

Known only from grassland and Empetrum-heath, apparently not attached to rock, at three different localities from c. 500–650 m


Threats

Area is subject to grazing by sheep


Conservation Actions


Research needed

Survey of Mt Maria and other montane heaths on the Falkland Islands (e.g. Mt Adam, Mt Usborne) to assess the current status of this species
