Pavement Moss

Bryum urbanum

Generation 3 · descended from Bryum argenteum (Silver Moss) · evolved in urban

The Pavement Moss descended from Bryum argenteum, adapting to the urban environment's challenges. It developed an extreme tolerance to desiccation and rapid rehydration capabilities, allowing it to thrive on flat, sun-exposed surfaces like pavement and building facades. Its dense mats help retain moisture, enabling it to survive in areas with limited rainfall.
