Assessment Notes

Taxonomic notes

Perichaena depressa is easily recognized by its sessile sporocarp strongly flattened with a yellow linear dehiscence.

Why suggested for a Global Red List Assessment?

Although to be a well distributed species, in Brazil this species need attention because many records are from endangered biomes. Thus, I suggest this species to be categorized in Least Concern.

Geographic range

The specie is known in 67 countries, in Brazil it is known in 13 of the 26 states (AL, BA, PB, PE, PI, RN, SE, CE, DF, RJ, SP, RS and SC). There is wide distribution in Brazil’s northeast.

Population and Trends

There are about 3253 records in 67 countries.

Population Trend: Uncertain

Research needed

More researches in Brazil are necessary, mostly in north region which has no record, also field collection and moist chamber techniques using various types of substrate.
