Collemopsidium sublitorale (Leight.) Grube & B.D. Ryan 2002
fungi species in the xanthopyreniaceae family
Collemopsidium sublitorale is a species of lichen in the family Xanthopyreniaceae. First described in 1871, it forms a "borderline" symbiotic relationship with cyanobacteria that is less structured than typical lichen partnerships. The species is characterised by an immersed thallus and black, roughly spherical fruiting bodies measuring 0.15–0.55 mm in diameter. It inhabits the intertidal and littoral fringe of marine environments, where it grows exclusively on calcareous surfaces such as limestone and marine shells. Its range includes north-west Europe and the Pacific coast of North America
Collemopsidium elegans (R. Sant.) Grube & B.D. Ryan 2002
fungi species in the xanthopyreniaceae family

First recognized in 1937 and formally described by the Swedish lichenologist Rolf Santesson in 1992, it is distinguished by its dark brown thallus that forms rosettes up to 10 mm in diameter bearing characteristic black ridges and warts. The species inhabits the intertidal zone, particularly on siliceous rocks, where it commonly associates with barnacles and other marine lichens. It has a wide geographic distribution, occurring along the Atlantic coast of Europe from Norway to
