Assessment Notes

Taxonomic notes

This species is known by the presence of a distinct white margin higher than the thallus, and individual lirellae often separated by white pruinose sterile areas. Also, it is known by the presence of stictic acid.

Why suggested for a Global Red List Assessment?

In Brazil, there are 142 records distributed in ten different states, being the majority of the records to the Northeast, then followed by North and South. Even knowing that tropical forest remains suffering deforestation, this species might be considered as Least Concern.

Geographic range

This is species is known in 29 countries. In Brazil, this species is mostly located at the Northeast and North Regions of Brazil.

Population and Trends

There are 452 records in GBIF database, where 142 records to Brazil, 82 to Australia, 58 to Costa Rica, and the others are distributed in small percentages to the other countries.

Population Trend:

Habitat and Ecology

This species is related to Tropical Forest and Rainforest, Gondwana Rainforest, Dense Low Forest, Wet Tropical forest, and Swamps, especially related to primary and secondary forest remnants. In Brazil, This species can be found at the Atlantic Rainforest.

Subtropical/Tropical Moist Lowland Forest


In Brazil, due to this species related biomes, Atlantic Rainforest that suffers anthropic actions, this species is exposed to natural and human-caused factors that rule its diversity and abundance.

Conservation Actions

Worldwide, this is species is always related to natural forest areas without human-directed activities or in preserved remanets, so the urge in low and management to those areas seems reasonable to the security of this species population. In Brazil, the highest numbers of records are also correlated to preserved areas, but unfortunately, those spaces still being affected by negatives influences. So, formal education to the population that lives near those areas and the park managers can start to change the situation.

Research needed

Remains unknown distribution and trends to this specie even knowing the numbers of records already. Also, the taxonomic studies can clarify a few morphological issues that are particular to this species.
