Ramalinaceae
The Ramalinaceae are a family of lichen-forming fungi in the order Lecanorales. First proposed by Carl Adolph Agardh in 1821, the family now comprises 63 genera and about 750 species. Ramalinaceae lichens exhibit diverse growth forms, including crustose, fruticose, squamulose, leprose, and byssoid thalli, and form symbiotic relationships primarily with green algae of the genus ''Trebouxia''. The family is characterised by pale-coloured thalli, apothecia (fruiting bodies) that are typically pale but may darken with age, and ascospores that vary in shape and septation. Members of the Ramalinaceae are found in a wide range of habitats worldwide, from coastal fog deserts to boreal, temperate, and tropical forests. Some genera, such as '' Namibialina'', '' Vermilacinia'', and '' Niebla'', are endemic to specific coastal desert regions, whilst others like '' Ramalina'' have an almost worldwide distribution. Several species within the family face conservation challenges due to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramalina
''Ramalina'' is a genus of greenish fruticose lichens that grow in the form of flattened, strap-like branches. Members of the genus are commonly called strap lichensField Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, or cartilage lichens. Apothecia are lecanorine. It is in the family Ramalinaceae and in the suborder Lecanorineae. Description The genus ''Ramalina'' consists of shrubby (fruticose) lichens that often appear tufted, ranging from erect to hanging () forms. The of the thallus, which is the body of the lichen, typically emerge from a well-defined or more spread-out holdfast—a structure that anchors the lichen to its substrate. In rare cases, these lichens can be free-living, unattached to any surface. The branches within the thallus can vary from singular to many, and their branching pattern may be either regularly forked (dichotomous) or more irregular. These branches are commonly compressed and strap-shaped, although they can occ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vermilacinia
''Vermilacinia'', a genus of lichenized fungi in the family Ramalinaceae, is a yellow-green fruticose type of lichen with about 30 species that grow on rocks, trees, and soil within the fog zone along the Pacific Coast of North America and South America.Spjut, R. W. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Miscellany 14 The genus name refers to the thallus being divided into narrow worm-like (vermis) branches (lacinia);the latter part of the name (lacinia) generally applied in descriptions and taxonomic keys such as exemplified in a key to Sonoran Desert species of ''Ramalina''. The species of ''Vermilacinia'' are classified in two subgenera: subgenus ''Cylindricaria'' and subgenus ''Vermilacinia''. Subgenus ''Cylindricaria'', which includes 10+ species (type: ''Vermilacinia corrugata'' Spjut) that grow mostly on shrubs, is distinguished by a thin membranous pliable cortex (an outer skin-like layer composed of gelatinized hyphal c ...
