Lecaimmeria
''Lecaimmeria'' is a genus of lichen-forming fungi in the family Lecideaceae. Established in 2022, it comprises 13 species of lichens that grow on rock surfaces (saxicolous) and form a thin, crust-like covering (crustose) on their substrate. These lichens are characterised by their glossy, orange to red-brown outer layer (thallus) and sunken fruiting bodies (apothecia) with red-brown centres. ''Lecaimmeria'' species are typically found in harsh environments at high altitudes or latitudes, particularly in mountainous regions of western China and across parts of Eurasia. The genus was created to accommodate species previously classified under ''Immersaria'' that shared certain distinct features, following molecular phylogenetics, molecular analysis that revealed they formed a separate group. Taxonomy ''Lecaimmeria'' was circumscription (taxonomy), circumscribed as a new genus in 2024 by Cong-Miao Xie, Lu-Lu Zhang, and Li-Song Wang to accommodate species previously placed in ''Immer ...
