This species is known by its filamentous, prostrate and effuse yellow-green thallus, rounded yellow-orange apothecia, ellipsoid, and 1-septate ascospores, 6-9 × 2-3 μm. Coenogonium interplexum forms the center of another group of taxonomically difficult, filamentous species of the genus, including also C. disjunctum, C. implexum, C. pannosum, and C. velutinum (Rivas Plata et al., 2006).

This is species is known in 23 countries, with 153 records in GBIF database. Also, this species occurs in Tropical area. In Brazil, this species records are related to Atlantic Rainforest and Amazon Rainforest. Due to all the previous information this species might be considered as Near Threatened (NT) until a better understanding.

This is species is known in 23 countries. In Brazil, two occurrences to this species are known, located in North, Northeast, and South of Brazil according to GBIF database.

There are 153 records in GBIF database, distributed in The United States of America (54 records), Brazil (34 records), Australia (8 records), Chile (8 records), and the other occurrences are distributed in small percentages.

This species is corticolous and sometimes foliicolous in understory of Lowland Montane Rainforest. In Brazil, this species can be found at the Atlantic Rainforest in Northeast and South of Brazil, and at the Amazon Rainforest in North of Brazil.

In Brazil, this species can be founded in Atlantic and Amazon Rainforest that are biomes that still suffer anthropic actions in special wildfire, natural and criminal caused, and area suppression.

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.

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