Lithocalla
''Lithocalla'' is a small genus of lichen-forming fungi in the family Ramalinaceae. It comprises two known species that form crust-like growths with a powdery texture on rocks. The genus was established in 2020 based on genetic analysis of species previously classified under different genera. ''Lithocalla'' lichens are characterised by their pale yellow-green colour and their preference for sheltered, shaded rock surfaces. They lack visible reproductive structures and likely spread through fragmentation. The two species have distinct geographical distributions: '' L. ecorticata'' is found mainly in Great Britain and Norway, while '' L. malouina'' is native to the Falkland Islands. Taxonomy The genus Lithocalla was erected in 2020 by Alan Orange to accommodate two species of leprose lichens containing usnic acid. It is placed in the family Ramalinaceae, order Lecanorales, though its exact phylogenetic position within the family remains uncertain. The genus name ''Lithoc ...
