Assessment Notes
Justification
Ceratoporia perplexa is a resupinate species known only from its type specimen, described in 2002 from Brazil. Further records are needed to estimate the population size and distribution, and the species is assessed as Data Deficient (DD).Taxonomic notes
This is the type and only species in the Ceratoporia genus, established in 2002 based on its morphological characteristics (Ryvarden and de Meijer 2002).Geographic range
Ceratoporia perplexa is known only from its type locality, a small urban forest fragment within the southern Brazilian Atlantic Forest, in Paraná, which since 1978 has been managed as an experimental area for forestry research (Colombo; Centro Nacional de Pesquisa de Florestas).Population and Trends
Ceratoporia perplexa is the only species within its genus, known only from one site within the southern Brazilian Atlantic forest, its type locality, which is a small urban forest fragment currently used as an experimental area for forestry research. The species was collected more than 20 years ago, and never found again. Any reliable population size inference is currently hindered by a lack of data, as the species is known only from its original publication. Nevertheless, the southern Brazilian Atlantic Forest has undergone decades of sampling efforts from several mycologists, indicating that the species might be rare throughout its potential habitat. Additionally, the Brazilian Atlantic Forest is severely fragmented, being now reduced to only 28% of its original size, and being mainly composed by secondary fragments (Rezende et al. 2018), indicating that the species' unknown population could be threatened by habitat area and quality loss.
Population Trend: Unknown
Habitat and Ecology
Ceratoporia perplexa is an annual resupinate species, found growing on decayed branch of dicotyledonous tree, in mixed ombrophilous forest (Ryvarden and Meijer, 2002), within a small experimental urban forest fragment in the southern Brazilian Atlantic Forest. Its specific habitat requirements (both biotic and abiotic) and ecology are unknown.Threats
The Brazilian Atlantic Forest, the only ecoregion where the species was found, is considered a biodiversity hotspot, being severely fragmented and reduced to only 28% of its original area (Rezende et al. 2018), suffering pressures due to urban expansion, deforestation, and agriculture. The scale of the impact of such threats on this species, however, are unknown.Conservation Actions
Specific conservation actions designed to protect the species' population are currently hindered due to lack of understanding of its distribution and population size. However, the protection of its type locality and adjacent areas could be beneficial to guarantee that the species is, at a minimum, protected until more of its ecological and population aspects are known.Targeted search efforts and research into its ecology and habitat preferences are needed to establish the population size and full distribution. Given that this is a monotypic genus, further research into its taxonomy is also recommended, namely through molecular analysis.
