Assessment Notes

Taxonomic notes

This species is known by its corticolous smooth to uneven, olive-green thallus, lirellae densely aggregate in pseudostromatic, 8- ascospores per ascus, ellipsoid, transversely 3–septate, 15–20 × 5–7 μm (Lucking et al., 2011). Important note, this species was first considered as F. mexicana. However, F. mexicana has muriform ascospores and its thallus is lighter, with a less conspicuous contrast between thallus and pseudostromatic clusters (Lucking et al., 2011).

Why suggested for a Global Red List Assessment?

Due to lack of records, and also the geographic distance between the existent records this species might be considered as Data Deficient (DD).

Geographic range

This is species is known in four countries. In Brazil, 25 occurrences to this species are known, located in South, North, and Northeast of Brazil according to GBIF database.

Population and Trends

There are 26 records in GBIF database, distributed in Brazil (25 records), The United States fo America (1 record). However, the database isn’t updated because there are records in Colombia (Rincón Espitia, 2011), and Thailand (Kawinnat Buaruang et al., 2017), so far.

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.
