Taxonomic notes

Rajchenberg (2001, 2006)


Why suggested for a Global Red List Assessment?

A wood decay polypore known from a single collection fruiting on fallen branches of Nothofagus betuloides (Nothofagaceae) in Tierra del Fuego. Never found on continental Patagonia in Argentina or Chile fruiting on other Nothofagus species; this possibly shows a restricted host specificity, rare fruiting possibility and/or restricted area distribution which requires appropriate protection. Surveys in Chile have never recovered this species.

Criteria
D1 VU due to low number of specimens


Geographic range

Tierra del Fuego Is., Argentina, where the host covers a narrow coastal area. Purported to be present on Chilean side and perhaps continental Chile following the host, but never found yet. Possible host restriction due to the fact that has never been found on other host in continental Patagonia in Argentina where polypore flora has been intensively surveyed in the past 25 years.


Population and Trends

A rare species with few occurrences, likely to be find in Chile but rare, not found after several surveys conducted.

Population Trend: Uncertain


Habitat and Ecology

A saprophyte decaying the wood of fallen branches of Nothofagus betuloides.


Threats

Highly restricted distribution.
Not found though other species that were originally described from Tierra del Fuego such as Inonotus crustosus (Speg.) J.E. Wright & J.R. Deschamps were widely found in continental Patagonia in the last 2 decades on other Nothofagus hosts following intensive surveys and field trips.


Conservation Actions

No conservation action is currently in place. Need of bettter documentation of its distribution.


Research needed

Mycological surveys in southern Chile in order to check its presence, Nothofagus betuloides being more widely distributed in that country.
