Woolly Rosette

Cotylidia pannosa

Unknown

Overview

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

The Woolly Rosette faces severe decline due to habitat destruction from agricultural expansion and urban development across its limited range. Climate change poses an additional threat through altered precipitation patterns that affect the specific moisture conditions this lichen requires. Collection pressure from botanical enthusiasts and researchers has also contributed to population reductions in accessible locations.

Threat summary

Habitat

The Woolly Rosette grows exclusively on the bark of mature deciduous trees in temperate forests, particularly favoring oak and maple species in areas with high humidity. It requires specific microclimate conditions with consistent moisture levels and minimal air pollution.
