Assessment Notes

Taxonomic notes

This species is known by its crustose, continuous and smooth, pale green-grey thallus, stellately branched lirellae, 8- ascospores per ascus, oblong to narrowly ellipsoid, 7-septate, 25–35 × 5–8 μm, 4–5 times as long as wide, colorless (Caceres, 2007).

Notes: G. pernambucoradians belongs in a difficult group of species that share the general morphology and anatomy of the lirellae and the ascospore type with G. scripta and related taxa but differ by their basally closed, completely carbonized excipulum (Caceres, 2007).

Why suggested for a Global Red List Assessment?

This is species is recorded to Brazil, with 24 records in GBIF database. So, the records are related to Atlantic Rainforest and Amazon Rainforest, biomes that suffers constantly anthropic actions. Due to all the previous information, this species might be considered as Vulnerable (VU) until a better understanding.
