Why suggested for a Global Red List Assessment?

Only collected and known living leaves from a single tree. The tree species, Coussapoa floccose, is globally red listed as VU which only is known with 12 trees in 4 localities despite being searched for during three years. The fungus was described in 2010. It is not known if the fungus is restricted to C. floccose or not.

Preliminary red-list assessment: VU D2 (vulnerable)

But scant information and only recently describe species would probably rather suggest it to be classified as DD (Data deficient).
If specific to this tree species it could be evaluated the same, e.g. VU. It could possibly be classified as NT using B1+2ab
The preliminary assessment consider it confined to C. floccose and few localities/restricted area of occurrence.


Geographic range

Brazil (Minas Gerais). The associated tree occurs only in a few tiny fragments of remaining Atlantic Forest. Altitude 725 m above sea level.


Population and Trends

Known only from living leaves of a single tree in the wild.

Population Trend:


Habitat and Ecology

The fungus grows on living leaves of Coussapoa floccose, and appears to be host-specific.


Threats

Habitat destruction. Loss of the few host trees remaining in the wild.


Conservation Actions

The individual host tree and the fragment of Atlantic Forest in which it is located need to be protected.


Research needed
