Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

The distribution of this species is limited to Nothofagus forests, which are under constant pressure for forestry and agricultural activities. Also, it is important to consider this species because it is the only secotioid bolete known in South America.
Highly fragmented distribution, restricted extent of occurrence <5000 km2 and restricted occupancy <500km2

Geographic range

Its distribution is limited to the coastal zone of the Bio Bio and Los Lagos regions in Southern Chile.
EOO 3.633 km2
AOO 300 km2


Population and Trends

Only 3 sites are known in southern Chile.

Population Trend: Deteriorating


Habitat and Ecology

This ectomycorrhizal species grows individually or in small scattered groups half buried in soil under native forest of Nothofagus (i.e. N. obliqua, N dombeyi). It’s distribution reaches 770 m of altitude. Distinctive in form and color, only known species of secotioid boletes in South America. Forms basiodiomes in autumn.

Forest

Threats

The major threat is the decline in the quality of native forest where this species is found. Despite being a striking fungus, this has been only 3 times in 30 years. There is a latent threat from excessive deforestation in its area distribution.
