Candelariella Efflorescens
''Candelariella efflorescens'', commonly known as the powdery goldfleck lichen, is a species of lichen in the family Candelariaceae. Found in North America, it was formally described as a new species in 1978 by Richard C. Harris and William R. Buck. The type specimen was collected by the second author from Hog Island Point State Forest Campground ( Michigan, USA); here, at the edge of a swamp, it was found growing on '' Populus balsamifera''. The lichen has a temperate eastern North American distribution. Although it occurs most frequently on bark (usually from deciduous trees), it has also occasionally been recorded growing on wood. Before its description as a new species, it had most often been confused with ''Candelariella xanthostigma ''Candelariella'' is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Candelariella
''Candelariella'' is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with '' Candelariella vitellina'' assigned as the type species. Characteristics The key feature of ''Candelariella'' species are the distinct yellow apothecia. Although all species are very small, even the smallest can be identified by the lemon-yellow to orange-yellow discs. Most species have a yellow thallus, although '' Candelariella antennaria'' is one example with a grey thallus. Some species are pycnidiate. This genus will generally have all spot tests emerge as negative, although K tests may have an orange or reddish colour on some species' apothecia. Spore count between species varies from 8 to 32 simply or thinly septate spores. Spores often hold one to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepraria Candelaris
''Lepraria'' is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains.A taxonomic revision of the North American species of Lepraria s.l. that produce divaricatic acid, with notes on the type species of the genus L. incana, James C. Lendemer , Mycologia 103(6): 1216-1229/ref> Members of the genus are List of lichen common names and their genera, commonly called dust lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The main vegetative body ( thallus) is made of patches of soredia (little balls of algae wrapped in fungus). There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products (i.e., secondary metabolites made by lichens) are important cha ...
