Botryolepraria is a genus of byssoid (cottony) lichens of uncertain familial placement in the order Verrucariales. It has two species. The thallus is an uncorticated, three-dimensional network of free fungal hyphae that holds clusters of green algal cells suspended within the lattice, so under low magnification it can resemble a pale, granular Lepraria-like crust. Reports are mostly from shady, humid, protected microhabitats on sheltered rock (often limestone) or on tree bark, including cave entrances and damp woodland or swamp habitats.

Xanthocarpia diffusa is a species of saxicolous (rock-dwelling) crustose lichen in the family Teloschistaceae. First described in 2011 from coastal rocks in Georgia, it is characterised by its yellow to greyish thallus with distinctive diffuse margins often bordered by a pale prothallus. The species primarily occurs along coastal areas of the Black Sea region, with some isolated populations in the Mediterranean region, where it grows on damp siliceous rocks, particularly around seepage zones and in areas exposed to sea spray. Though initially described in the genus Caloplaca, molecular
