Assessment Notes

Develop assessment

Taxonomic notes

The genetic analysis data suggest that this is a young taxon that needs to be preserved and studied.

Why suggested for a Global Red List Assessment?

Recently described as a new for science with easily recognizable secotioid fruit bodies (Crous et al., 2019). It is distributed in a small area in the North of the Russian Far East. The genetic analysis data suggest that this is a young taxon that needs to be preserved and studied.

Geographic range

There are 3 finds known from 1995, all of them in Magadan Oblast, Russia.

Population and Trends

Tree known populations occupy not more 0.1 ha at all. One habitat is eroded by floodwaters and may be lost.
Floodplains and valleys with the Larix take a extensive area on Far East but this species was find only on small territory.

Population Trend: Decreasing

Habitat and Ecology

All populations were find in wet mixed forests with Larix cajanderi: in floodplains and valleys of Kolyma river and its tributaries. We conclused that S.gastroflavus is mycorrhiza-forming with the Larix.

Boreal Forest


The main threats are floodwaters in floodplains and anthropogenic factors such as forests using and deforestation.

Unintentional effects (species being assessed is not the target)Type Unknown/Unrecorded

Conservation Actions

We need in conservation and monitoring of known habitats as well as new population searching. Suillus gastroflavus will be recommended in Red Book of Russia and Red Book of Magadan Oblast.
