Assessment Status Notes

Taxonomic notes

Forms a delicate basidiome with associated hyphal strands. It is distinguished by presence of gloeocystidia (Rajchenberg 2002).


Why suggested for a Global Red List Assessment?

The species’ only/restricted host is the conifer Austrocedrus chilensis which is in NT condition according to IUCN Red List. This fungal species is known from a restricted number of specimens in spite of a wide survey and search along the distributional range of the host in Argentina. There is a restricted number of specimens (4) and an apparent habitat restriction (features unknown) suspected to be related to humidity.

Criteria:
D2 E: this criterium applies on the basis of a very restricted population with all specimens found in a single location (valley of river Futaleufú, Chubut province, Argentina, see map provided).


Geographic range

Known from two localities:
Restricted to the river Futaleufú valley, Chubut province, Argentina


Population and Trends

Population Trend:


Habitat and Ecology

Fallen branches and wood of Austrocedrus chilensis. Apparently requiring special, unknown, habitat conditions possibly related to humidity.

Subantarctic Forest

Threats

Possible restricted distribution.
Host habitat loss through natural or human-set fires, invasive non-native tree species and/or establishment of plantation trees.

Fire & fire suppressionNamed species

Conservation Actions

Requirement of ecological needs of the species in order to set its natural distribution.

Site/area management

Research needed

Survey in Chile along the distributional range of the host. Additional efforts to find it elsewhere in Argentina.
