Assessment Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

This is a rare, easily identifiable species that has recently been described from Northern Thailand. Forests in the known distribution area are under threat from human activities like recurrent burning and tea or coffee plantation.


Geographic range

Known only from two sites in Chiang Mai Province, Northern Thailand


Population and Trends

Known only from two sites in Chiang Mai Province, Northern Thailand (Raspé et al. 2016; Raspé pers. obs.). In each site, production of basidiomes occur regularly, but population size is estimated to a maximum of 10 individuals.

Population Trend: Uncertain


Habitat and Ecology

In evergreen hill forests dominated by Fagaceae (Castanopsis spp., Lithocarpus spp.). Presumably ectomycorrhizal with Fagaceae. Production of basidiomes has never been observed at the beginning of the rainy season, but rather in July-August.

Subtropical/Tropical Moist Montane Forest

Threats

Forests cover in Northern Thailand was reduced by more than 75 % between 1915 and 1995, mostly because of conversion to cropland (Delang, 2002). Despite protection measures and reforestation, Thailand lost 7.8 % of Intact Forest Landscapes between 2000 and 2013 (Potapov et al 2017). In the area where Pulveroboletus fragrans is known to occur, forests continue to be degraded by human activities (e.g., tea or coffee plantation, recurrent burning).


Conservation Actions


Research needed

The distribution needs to be better known. The ectomycorrhizal symbiotic partners should be identified.


Use and Trade

No use known.
