Lecanographa Brattiae
''Lecanographa'' is a genus of about 20 species of lichens in the family Lecanographaceae. These lichens typically form thin, extensive crusts that can be chalk-white, grey, or pale green, with dark brown to black reproductive structures that are often covered in a dense frosting () of white, bluish, or greyish crystals. Established as a genus in 1994 by José M. Egea and Pilar Torrente, the lichens are characterized by their partnership with orange-tinged filamentous algae and their production of slender, spindle-shaped spore In biology, a spore is a unit of sexual reproduction, sexual (in fungi) or asexual reproduction that may be adapted for biological dispersal, dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores fo ...s with multiple septum, cross-walls that are wrapped in a gelatinous outer layer. Taxonomy The genus was circumscription (taxonomy), circumscribed in 1994 by José M. Egea and Pilar Torrente, with ''Lecano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lecanographa Dialeuca
''Lecanographa dialeuca'' is a species of saxicolous lichen, saxicolous (rock-dwelling) crustose lichen in the family Lecanographaceae. It is found in Cape Verde and Europe. Taxonomy It was first species description, described by Scottish James Stirton in 1874, with the name ''Opegrapha undulata''. The type (biology), type specimen was collected from Cape Verde, as part of the Challenger expedition, ''Challenger'' expedition of 1872–1876. James Mascall Morrison Crombie mentioned the species in an 1877 publication in which he revised and added his own notes about the lichens collected by Stirton. Crombie noted that the species was the same as one that he had named ''Opegrapha dialeuca''. It was later discovered that the name ''Opegrapha undulata'' had already been used by François Fulgis Chevallier in 1824, and consequently, Stirton's use of the name was validly published name, invalid. Because Crombie had noted synonym (taxonomy), synonymy with his ''Opegrapha dialeuca'', that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
