Assessment Notes

Taxonomic notes

This species was described in 1809 as Stereum damicornis by Link and was combined into Hymenochaete damicornis (Link) Lév. in 1846.


Why suggested for a Global Red List Assessment?

Hymenochaete damicornis is a species currently considered a parasite of live plant roots. The species has been recorded in the Neotropical region. Due to its extensive geographical distribution, the species is considered of Least Concern, despite occurring in the Brazilian Atlantic Forest, an environment under anthropogenic threats of fragmentation (Rezende et al. 2018).


Geographic range

The neotype of this species is from Brazil (São Leopoldo). In the Neotropical region, it is recorded for Brazil, within the domains of the Amazon, Cerrado, and Atlantic Forest. It has a wide occurrence in the North (Acre, Amazonas, Pará, Rondônia, Roraima), Northeast (Alagoas, Paraíba, Pernambuco, Piauí, Sergipe), Midwest (Mato Grosso), Southeast (São Paulo), and South (Paraná, Rio Grande do Sul, Santa Catarina). It has also been cited for North America (Dominican Republic, Cuba, Jamaica, Guadeloupe, Mexico), Central America (Belize, Costa Rica, Puerto Rico, Guatemala, Honduras, El Salvador, Panama), and South America (Peru, Argentina, Brazil, Venezuela, Colombia, Paraguay, Suriname, Bolivia, Guyana, French Guiana) (Ryvarden 1985; Azevedo & Guerrero 1993; Baltazar & Gibertoni 2009; Gomes-Silva & Gibertoni 2009; Gibertoni et al. 2012; Flora e Funga do Brasil 2024).


Population and Trends

The species has at least 810 records (GBIF 2024) throughout the Neotropical region. Hymenochaete damicornis was described in 1809 as Stereum damicornis Link from material from Brazil and is a parasite species of live roots. Despite being found in the Atlantic Forest region, an environment undergoing decline and fragmentation, it is recurrently found in the Neotropical region, making it of little concern.

Population Trend: Decreasing


Habitat and Ecology

Hymenochaete damicornis is currently considered a parasite on the roots of live woody plants, also found on the roots of Bambusa sp. and deciduous trees (Ryvarden 1985). It has potential as an ectomycorrhizal species.


Threats

The Mata Atlântica ecoregion is considered one of the most threatened tropical forests. In addition to forest cover loss due to urban expansion (Rezende et al. 2018).


Conservation Actions

Conservation actions have not been implemented for this species. Further research is needed to understand the ecology of the species, including confirming whether it is a mycorrhizal species. If it is proven to be mycorrhizal, it is necessary to investigate which species this fungus associates with. There is also a need for containment of anthropogenic actions in the face of the reduction of areas where the fungus occurs, such as the Atlantic Forest.

Research needed

Further research is needed to understand the ecology of the species, including confirming whether it is a mycorrhizal species. If it is proven to be mycorrhizal, it is necessary to investigate which species this fungus associates with. There is also an urgent need to contain anthropogenic actions in response to the reduction of areas where the fungus occurs, such as the Atlantic Forest. Additionally, the species requires phylogenetic studies, production of sensu stricto sequences, and subsequent genetic characterization.
