Assessment Notes

Taxonomic notes

Unique in the genus in the ascospores being mutiseptate and arranged spirally in the ascus.


Why suggested for a Global Red List Assessment?

Known only from native Hebe elliptica on a single off-shore island. Hebe elliptica, and hence this species, are seriously impacted by overgrazing and habitat destruction.


Geographic range

Known from only three locations on a single off-shore island (West Point Island). (AOO = 8 km2, EOO = 8 km2).


Population and Trends

Several collections from 3 localities along a 2 km stretch of coastal cliffs. Not seen since 1968.

Population Trend:


Habitat and Ecology

Known only from stems of native Hebe elliptica on Westpoint Island.


Threats

Grazing and destruction of native Hebe elliptica, which was once widespread on the Falkland Islands but is now found on only a few off-shore islands where it has escaped the effects of over grazing.


Conservation Actions

None


Research needed

Further surveys to ascertain the extent of the population at its known locality and of suitable habitats elsewhere.

Lecania vermispora has not been discovered elsewhere among the c 5,000 collections from the Falkland Islands nor in the c. 10,000 lichen collections from southern South America held in the herbarium of Michigan State University herbarium (MSC) so is evidently extremely rare. It is probably confined to the stems of native Hebe elliptica, which is now confined to the smaller islands of the archpelago.


Use and Trade

None
