Assessment Notes

Taxonomic notes

This species is known by its cream-colored to pale ochre thallus, thin, smooth, somewhat glossy. Ascomata lirellae, immersed, initially visible as pale parallel lines on the surface, 8 ascospores per ascus, hyaline, muriform (Kalb et al., 2004).


Why suggested for a Global Red List Assessment?

This is species is known in 11 countries, with 45 records in GBIF database. Also, this species occurs in South-East Asia, and Tropical areas. Due to all the previous information, and the new registers this species might be considered as Data Deficient (DD) until a better understanding.


Geographic range

This is species is known in 10 countries. In Brazil, no occurrences to this species are known according to GBIF database; however, there are two occurrences related to Brazil.


Population and Trends

There are 45 records in GBIF database, distributed in Australia (17 records), Indonesia (6 records), Papua New Guinea (6 records), and the other occurrences are distributed in small percentages.

Population Trend:


Habitat and Ecology

This species seems to be restricted to South-East Asia; however, with some new reports to Pantropical area too. In Brazil, only two records are known one to Northeast (Atlantic Rainforst) and one to North (Amazon Rainforest) of Brazil.

Threats

In Brazil, since two records are related to Atlantic and Amazon Rainforest that are biomes that still suffer anthropic actions in special wildfire, natural and criminal caused, and area suppression, attention to threats that can affect this species need to be taken seriously.

Conservation Actions

In Brazil, the records are related 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

Actions that are orientated to taxonomy and exploration to new sites need to be stimulated until a better understanding of this species status.
