Phaeophyscia kairamoi

Unknown

Overview

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

Phaeophyscia kairamoi faces significant pressure from air pollution and acid rain, which alter the chemical composition of its bark substrates and reduce lichen viability. Urban expansion and industrial development within its limited range have eliminated suitable host trees and degraded air quality in remaining habitat patches. Climate change compounds these threats by altering precipitation patterns and temperature regimes that affect both the lichen and its preferred tree hosts.

Threat summary

Habitat

This crustose lichen species grows exclusively on the bark of mature deciduous trees, particularly favoring oak and maple species in temperate forest environments. It requires specific microclimate conditions with moderate humidity and clean air quality, typically found in undisturbed woodland areas away from industrial pollution sources.
