Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Pseudocyphellaria aurata - Gilt-edged Lichen

b> Range & Status

One of the larger and most spectacular of British lichens. Until recently the species was thought to be extinct in its most recent site on the Isles of Scilly, with no confirmed records since 1967. In April 2001 a population was discovered on an island off St. Martins, Isles of Scilly. P. aurata is a widespread and frequent species in the tropics and some temperate areas of the southern hemisphere. It is frequent in Macronesia but is very rare in mainland Europe, being confined to the more hyperoceanic regions. There is one record from southwest Ireland, from Inishvickillane, the farthest west of the Blasket Islands, off the Dingle Peninsula. At present there are no apparent threats to the P.aurata population.
