Assessment Notes

Taxonomic notes

Arcyria leiocarpa is a synonym of Hemitrichia leiocarpa and can be easily confused with Arcyria cinerea which is distinguished by ornamentation capilitium examination.


Why suggested for a Global Red List Assessment?

Hemitrichia leiocarpa is found in Brazil only in Atlantic Forest, which has its biodiversity threatened. Also, during a century of collections, only 03 records were found in the last 51 years.


Geographic range

Hemitrichia leiocarpa is known in 27 countries. In Brazil it is known in Pernambuco and Alagoas. There are 10 occurrences on GBIF for Pernambuco, but they actually represent 10 records of only one sample, which is preserved in BPI herbarium (Bezerra et al., 2009, Cavalcanti, 2010), and 02 records for Alagoas (unpublished records).


Population and Trends

Brazil has three occurrences of Hemitrichia leiocarpa, one in Pernambuco in 1968 and two in Alagoas in 2019. Hemitrichia leiocarpa is considered a rare species (Martin & Alexopoulos, 1969, Stephenson, 2011).

Population Trend: Uncertain


Habitat and Ecology

The species can be found in herbivore dung, mosses, wood and dead leaves.

Subtropical/Tropical Moist Lowland Forest

Threats

Hemitrichia leiocarpa in Brazil is collected in the Atlantic Forest domain, which has been losing its biological diversity resulting in species extinction.
