Nanostictis peltigerae

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Nanostictis peltigerae faces severe threats from air pollution and acid rain, which directly damage its lichen host Peltigera membranacea. Climate change compounds these pressures by altering moisture regimes essential for both the fungus and its substrate. The species' extremely limited distribution makes it particularly vulnerable to local environmental changes and habitat degradation.

Threat summary

Habitat

This microscopic fungus is exclusively found on the foliose lichen Peltigera membranacea in old-growth coniferous forests. It requires the specific microclimate conditions provided by mature forest ecosystems with stable humidity and minimal disturbance.
