Overview
Orthotrichum patens is a small acrocarpous moss species that forms dense, cushion-like tufts on tree bark and occasionally rock surfaces. The moss displays characteristic curved, ribbed capsules when fertile and has narrow, lance-shaped leaves that often curl when dry, giving colonies a distinctive twisted appearance that aids in moisture retention.
Orthotrichum patens faces significant threats from air pollution and habitat degradation, as this epiphytic moss is highly sensitive to changes in air quality and substrate availability. Urban development and industrial activities have reduced suitable habitat and increased atmospheric pollutants that directly impact moss survival and reproduction.
Habitat
This epiphytic moss grows on the bark of deciduous trees, particularly in urban parks, roadside trees, and scattered woodland areas. It typically colonizes smooth-barked trees in semi-open environments with moderate light exposure.
