Bellemerea Cupreoatra
''Bellemerea'' is a genus of saxicolous lichen, saxicolous (rock-dwelling) crustose lichens in the family Lecideaceae. These lichens form tough, crusty patches on hard rock surfaces, often appearing as a mosaic of small angular blocks in colours ranging from white and grey to brown. The genus includes nine species found primarily in montane ecosystem, mountainous and Polar regions of Earth, polar regions where they help colonisation (biology), colonize bare rock surfaces in harsh environments. Taxonomy The genus was circumscription (taxonomy), circumscribed in 1984 by Josef Hafellner and Claude Roux, with ''Bellemerea alpina, B. alpina'' as the type species. The generic name honours the French lichenologist André Henri Bellemère (1927–2014). Description ''Bellemerea'' species form firmly attached, crust-like colonies on hard, often siliceous rock. Seen close up, the surface is broken into angular blocks or low warts () that may be scattered or jammed tightly togethe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bellemerea Alpina
''Bellemerea alpina'', the brown sunken disk lichen, is a white to pale tan, thick crustose lichen, crustose areolate lichen that grows on rock in the mountains worldwide. It grows in arctic-alpine habitats in Eurasia, North America (south to California and Arizona), Australia, and New Zealand.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Areoles are sometimes contiguous and sometimes dispersed. It often has very visible black prothallus. The brown to tan apothecia have a purplish tinge and are grayed by a pruinose coating, and embedded in the areoles, giving a similar appearance to members of the genus ''Aspicilia''.
