Grimmia Kidderi
''Grimmia'' is a genus of mosses (Bryophyta), originally named by Jakob Friedrich Ehrhart in honour of Johann Friedrich Carl Grimm, a physician and botanist from Gotha, Germany. Geographic distribution Although predominantly occurring in the moderate zones, representatives of the cosmopolitan genus ''Grimmia'' may be found in all parts of the world, from Alaska to the most southern point of Chile, and from Siberia to South Africa, though in tropic regions, e.g. Hawaii and Indonesia, ''Grimmia'' species only occur high up in the mountains. Identification ''Grimmia'' is a notoriously difficult genus in terms of identification, and in the majority of herbaria a considerable number of species was found misidentified. The American bryologist Geneva Sayre (1911–1992), who worked for many years on a monograph of the North American ''Grimmias'', indicated in an original way these difficulties, as she said: "it contains an ambigua, a varia, a decipiens, a controversa, a revis ...

Grimmia Pulvinata
''Grimmia pulvinata'', otherwise known as grey-cushioned grimmia or pulvinate dry rock moss, is a bryophyte moss common in temperate climates worldwide. Characteristics ''Grimmia pulvinata'' grows in small cushion-like shaped, around 1-2 centimeters tall. Its color ranges from a grey-green to an orange-yellow. Its leaves are lanceolate, being broad and oval shaped at the base and very narrow toward the tip. They may show a silvery hue near the tip in some specimens. Its capsules are oval shaped, and bend back into the leaves when the plant is dry, and stand out when it is moist. 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. However, it prefers surfaces such as old mortar and tree trunks. Distribution ''Grimmia pulvinata'' is the most common species in the genus '' Grimmia'', with a nearly worldwide distribution. ...
