Description
The Incurved Grizzled Moss grows in small blackish-green tufts in crevices on dry rocks and on the base of trees in deciduous forests. The leaves, which measure about two millimetres in length, are narrow, concave, and rounded at the hood-shaped apex. They are curled when dry and erect-spreading and somewhat incurved when moist. They are characteristically glossy. The sporophyte (a spore-filled capsule) is erect, reaching up to five millimetres in height.
Action we are taking:
Current Range
Incurved Grizzled Moss is found in eastern North America and Europe. It is considered relatively common in the southeastern United States.
Historical Range in Ontario
In Canada, the only known location for the species is a single record dated 1828 from a boulder near Niagara Falls in southern Ontario. The species has never been rediscovered here.
Why It Disappeared from Ontario
Pollution and habitat destruction may have contributed to the apparent loss of Incurved Grizzled Moss from southern Ontario. However, the causes of its apparent rarity in the early 19th Century and its subsequent disappearance are not well understood.
Habitat
This small moss grows in eastern deciduous hardwood forests, inhabiting surfaces or tiny crevices of exposed or protected rocks of variable types. It rarely occurs at the base of trees or on logs.
