Biatorina-tensporelav

Bacidia biatorina

Unknown

Overview

Bacidia biatorina is a crustose lichen species that forms thin, grayish to pale greenish crusts on various substrates. This lichen produces small, dark apothecia (fruiting bodies) and plays an important ecological role as a primary colonizer, contributing to soil formation and providing microhabitats for invertebrates in its ecosystem.

Bacidia biatorina faces significant threats from air pollution and acid rain, which alter the chemical composition of its substrate and can severely impact lichen communities. Habitat loss through deforestation and urban development further reduces available colonization sites, while climate change may shift suitable environmental conditions beyond the species' adaptive capacity.

Threat summary

Habitat

This crustose lichen species typically grows on the bark of deciduous and coniferous trees in temperate forests, particularly favoring smooth-barked trees in humid woodland environments. It can also be found on wooden substrates and occasionally on rock surfaces in shaded forest settings.
