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 recorded in Brazil only in Atlantic Forest, which has its biodiversity threatened. Also, during a century of collections, only 3 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 from Pernambuco, but it is actually represent 10 records of only one sample, which is preserved in BPI herbarium (Bezerra et al., 2009, Cavalcanti, 2010), and 02 records from Alagoas (unpublished).
Population and Trends
Brazil has three records 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
In Brazil this species is found in leaf litter and decomposing trunk.
Threats
Hemitrichia leiocarpa in Brazil is recorded only in the Atlantic Forest, which has been losing its biological diversity resulting in species extinction.
Conservation Actions
Of the 3 records, 1 was in unprotected area.
Research needed
More researches in Brazil are necessary concerning field collection and moist chamber techniques using various types of substrate.
Use and Trade
None.
