Porina lectissima

Unknown

Overview

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

Porina lectissima faces severe pressure from atmospheric pollution, particularly acid rain and nitrogen deposition, which alter the chemical composition of its bark substrates and disrupt the delicate pH balance required for lichen survival. Urban expansion and industrial development have eliminated many of its traditional host trees, while air quality degradation in remaining habitats continues to reduce population viability across its limited range.

Threat summary

Habitat

This crustose lichen species grows exclusively on the smooth bark of deciduous trees, particularly favoring mature specimens in old-growth and semi-natural woodland environments. It requires stable microclimatic conditions with consistent humidity levels and minimal air pollution, typically found in undisturbed forest ecosystems.
