Flavoplaca
''Flavoplaca'' is a genus of crust-like or scaly lichens in the family Teloschistaceae. It has about 30 species with a mostly Northern Hemisphere distribution. Taxonomy The genus was circumscribed in 2013 by Ulf Arup, Patrik Frödén and Ulrik Søchting, with '' Flavoplaca citrina'' as the type species. The genus formed a well-supported clade in molecular phylogenetics analysis. ''Flavoplaca'' species are closely related to '' Calogaya'' species that have lobes. There are other genera with roughly similar morphological features as ''Flavoplaca'' (examples include '' Polycauliona'', '' Orientophila'', '' Sirenophila'', and '' Villophora''), but they are genetically different and have different distributions. Arup and colleagues included 26 species in the genus; most were originally named as members of the genera '' Caloplaca'' or ''Lecanora''. Recent molecular studies have continued to refine the taxonomy of the genus. In 2024, three additional species were transferred to '' ...

Flavoplaca Oasis
''Flavoplaca oasis'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed across Europe, and has been reported in Western Asia, China, and North Africa. Taxonomy It was first formally described in 1856 by the Italian lichenologist Abramo Bartolommeo Massalongo, as a variety of ''Callopisma aurantiacum''. Ödön Szatala promoted it to distinct species status in 1932, classifying it in the genus ''Caloplaca''. Ulf Arup and colleagues transferred the taxon to the genus ''Flavoplaca'' in 2013, following a molecular phylogenetics-based restructuring of the family Teloschistaceae. Description The lichen ''Flavoplaca oasis'' has a typically visible yet thin thallus, characterised by small or , particularly noticeable at the . The thallus presents a pale yellow hue. It features an (honeycomb-like) cortex, and its is distinctly separated by fungal hyphae. This species lacks a prothallus and does not produce vegetative pro ...

Flavoplaca Citrina
''Flavoplaca citrina'', the mealy firedot lichen, is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is a common species with a cosmopolitan distribution. Taxonomy ''Flavoplaca citrina'' first scientifically described and named in 1796 by the German lichenologist Georg Franz Hoffmann, who initially placed it in the genus ''Verrucaria''. Ulf Arup and colleagues transferred the taxon to the genus ''Flavoplaca'' in 2013, following a molecular phylogenetics-based restructuring of the family Teloschistaceae. Throughout its taxonomic history, the species has accumulated numerous synonyms due to multiple redescriptions and reclassifications, including various designations as varieties or forms of other species. Description ''Flavoplaca citrina'' is a crustose (crust-like) lichen with a yellow-green thallus (the main body of the lichen). The thallus is (powdery) and entirely covered with granular soredia (tiny, powdery reproductive propagu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flavoplaca Flavocitrina
''Flavoplaca flavocitrina'' is a species of crustose lichen in the family Teloschistaceae. Found in Europe, it was originally described as a new species in 1886 by the Finnish lichenologist William Nylander, who classified it as a member of the genus ''Lecanora''. After having spent time in various different genera throughout its taxonomic history, it was reclassified in the genus ''Flavoplaca'' in 2013 following a molecular phylogenetics Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships.

Teloschistaceae
The Teloschistaceae are a large family (biology), family of mostly lichen-forming fungi belonging to the class (taxonomy), class Lecanoromycetes in the division (botany), division Ascomycota. The family has a cosmopolitan distribution, although its members occur predominantly in temperate climate, temperate regions. Most members are lichens that either saxicolous lichen, live on rock or corticolous lichen, on bark, but about 40 species are lichenicolous fungus, lichenicolousmeaning they are non-lichenised fungi that live on other lichens. Many members of the Teloschistaceae are readily identifiable by their vibrant orange to yellow hue, a result of their frequent anthraquinone content. The presence of these anthraquinone biological pigment, pigments, which confer protection from ultraviolet light, enabled this group to expand from shaded forest habitats to harsher environmental conditions of sunny and arid ecosystems during the Late Cretaceous. Teloschistaceae lichens typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caloplaca
''Caloplaca'' is a lichen genus comprising a number of distinct species. Members of the genus are commonly called firedot lichen, jewel lichen.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, gold lichens, "orange lichens", but they are not always orange, as in the case of '' C. albovariegata''. The distribution of this lichen genus is worldwide, extending from Antarctica to the high Arctic. It includes a portion of northern North America and the Russian High Arctic. There are about thirty species of ''Caloplaca'' in the flora of the British Isles. A new species of ''Caloplaca'', '' C. obamae'', the first species to be named in honor of Barack Obama, was discovered in 2007 on Santa Rosa Island in California and published in March 2009. Taxonomy ''Caloplaca'' was circumscribed in 1860 by Theodor Magnus Fries. Until relatively recently, ''Caloplaca'' was one of the largest genera of lichen-forming fungi, with more than 500 species.

Hydropunctaria Maura
''Hydropunctaria maura'', still often called by the older name ''Verrucaria maura'' and commonly known as tar lichen, is a species of saxicolous (rock-dwelling), crustose lichen belonging to the family Verrucariaceae. A perennial species that does not experience seasonal variations, it is the type species of the genus ''Hydropunctaria''. The medulla is a black basal layer that forms columns (Latin: ''punctae'') to the upper surface and isolates the algae into pockets near the upper surface. The black band formed by ''H. maura'' can often be seen at a distance as a marker of the high water point. Ecology ''Hydropunctaria maura'' is commonly found on hard rocks in the intertidal zone. Compared to terrestrial lichens, the species is typically located in areas of direct sunlight, suggests that it may have specific adaptations against damage from the sun. It is considered an upper littoral (supralittoral) lichen, compared to other, lower littoral lichens such as '' Wahlenberg ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Lichenicolous Fungus
A lichenicolous fungus is a member of a specialised group of fungi that live exclusively on lichens as their host organisms. These fungi, comprising over 2,000 known species across 280 genera, exhibit a wide range of ecological strategies, including parasitism, commensalism, and mutualism. They can be found in diverse environments worldwide, from tropical to polar regions, and play important roles in lichen ecology and biodiversity. Lichenicolous fungi are classified into several taxonomic groups, with the majority belonging to the Ascomycota and a smaller portion to the Basidiomycota. Their interactions with host lichens range from mild parasitism to severe pathogenicity, sometimes causing significant damage to lichen communities. While the study of lichenicolous fungi dates back to the mid-18th century, recent decades have seen significant advancements through modern research methods, including molecular techniques, metagenomics, and sophisticated imaging. These fungi show vary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
