Andreaea rupestris
Also called Black Rock Moss
Andreaea rupestris is a species of moss in the class Andreaeopsida, are commonly referred to as the "lantern mosses" due to the appearance of their dehisced sporangia. It is typically found on smooth, acidic, exposed rock in the Northern hemisphere. It exhibits the common features of the genus Andreaea such as being acrocarpous, having dark pigmentation, lacking a seta, and bearing 4 lines of dehiscence in its mature sporangia, but can be further identified upon careful examination of its gametophytic leaves which have an ovate base to a more blunt apex compared to other similar species.
Andreaea rupestris are typically found in cooler climates on surfaces or fissures of dry, siliceous, exposed rock such as granite. While they can also grow in neutral to mildly basic conditions, they are usually found on acidic rocks and cliff walls. They can be found from sea level to high elevations, but are more commonly associated with higher altitudes. Compared to other species in their genus, they can withstand a wider variety of moisture levels and are better at surviving in drier conditions. They have been found to grow with other species of their genus such as Andreaea nivalis, A. blyttii, A. rigida, A. crassinervia, A. rothii ssp. rothii, A. rothii ssp. jalcata, A. alpina, and A. obovata.
