Grimmia pulvinata, otherwise known as grey-cushioned grimmia[1] or pulvinate dry rock moss,[2] is a bryophyte moss common in temperate climates worldwide.

Características Grimmia pulvinata crece en forma de pequeños cojines, alrededor de 1-2 centímetros de alto. Su color varía de un verde grisáceo a un amarillo anaranjado. Sus hojas son lanceoladas, son anchas y de forma ovalada en la base y muy estrechas hacia la punta. Pueden mostrar un tono plateado cerca de la punta en algunos especímenes. Sus cápsulas son de forma ovalada, y se doblan hacia atrás en las hojas cuando la planta está seca, y se destacan cuando está húmeda.

Habitat

Grimmia pulvinata colonizes a variety of surfaces including rocks, concrete, and tree trunks. It is tolerant of a wide range of PH levels on surfaces, allowing it to live on many types of rock.[3]

However, it prefers surfaces such as old mortar and tree trunks.[4]

Distribution

Grimmia pulvinata is the most common species in the genus Grimmia, with a nearly worldwide distribution.[3] It is particularly common in Britain[5] and the west coast of North America.[6] It primarily lives in temperate regions, from sea level to elevations up to 9800 feet.[3]

Ecological role

Grimmia pulvinata is a pioneer species, meaning it is among the first organisms to colonize habitat which has been disturbed by an event such as a forest fire.[7] In addition, its resistance to pollution allows it to colonize urban areas such as roofs, walls, and tarmac.[8]
