Assessment Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

This species is the ectomycorrhizal fungus that lives only in symbiosis with the critically endangered Pinus amamiana. Therefore, I think that this species should also be included in the Red List.


Geographic range

This species is found only in the Pinus amamiana stands. Pinus amamiana is only present onYakushima and Tanegashima Islands, Kagoshima Prefecture in Japan.


Population and Trends

This species is only sympatric with Pinus amamiana, so the population size is also dependent on the tree. The host population is approximately 2300 (Yakushima: 2000, Tanegashima: 300) individuals and is decreasing.

Population Trend: Decreasing


Habitat and Ecology

This species is the ectomycorrhizal fungus that lives only in symbiosis with the critically endangered Pinus amamiana. Therefore, the fungus is only present in forests dominated by P. amamiana. In addition, the fungus is hypocarpogean which produces fruiting bodies in the soil and the dispersal of its spores is dependent on animals.

Temperate Forest

Threats

The threat of this species is the same as the threat of endangered Pinus amamiana, as this species cannot survive without its host.

Scale Unknown/UnrecordedIntentional use: subsistence/small scale (species being assessed is the target) [harvest]Named species

Conservation Actions

As this species has only recently been discovered, there has been no conservation action done on it. On the other hand, All areas where Pinus amamiana, the host of this species, is present are protected. NPOs are active on Yakushima and Tanegashima with the aim of conserving P. amamiana.
