Assessment Notes

Taxonomic notes

Perichaena chrysosperma is easily recognized by its horseshoe or ring-shaped plasmodiocarp.

Why suggested for a Global Red List Assessment?

Geographic range

Perichaena crhysosperma is recorded in 75 countries. Brazil has 115 records shown in GBIF, added to that, there is 1 record from Alagoas state (unpublished) resulting 116 records, thus it is known in 9 of the 26 states.

Population and Trends

There are 2907 records in the world according to GBIF, of which 115 are from Brazil.

Population Trend: Uncertain

Habitat and Ecology

In Brazil occur in pre-Amazonian forest environments, lowland dense ombrophilous forests, semi-deciduous seasonal forests, restinga forests, caatinga and rupestrian field, in northeast region can be found in natural environments as well as in urban parks, backyards and home gardens, sporulating in almost all months of the year, but reaching its peak in the rainy season. It is mostly lignicolous, however, it occupies other microhabitats as well, developing on the cortex of living trees, on ground litter and on succulent and plant inflorescences (Cavalcanti et al., 2016)

In Brazil, besides occuring in Atlantic and pre-Amazon forest, which has the highest rates of deforestation, many records are from human observation and occurr in unprotected area.

Conservation Actions

Many records are in unprotected areas in Brazil.

Research needed

More researches in Brazil are necessary mostly in north and central west, concerning field collection and moist chamber techniques using various types of substrate.
