Status: Native
Synonyms:
Grimmia affinis Hoppe & Hornsch. ex Hornsch.
Grimmia longirostris grows on rocks as do most species in the genus, but it looks greener than other Grimmias here. It has short to medium sized hair points on many of the leaves, but some of the leaves have no hair point at all. The calyptra is distinctive-- short, mitrate (splits in many places rather than just on one side) and it has a very long "nose" giving rise to its name "longirostris." The basal juxtacostal cells are also useful for identification in the lab as they are long rectangular to almost linear, with thickened and nodose lateral walls and thin transverse walls.
