Hydropunctaria Rheitrophila
''Hydropunctaria rheitrophila'' is a species of freshwater, saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. It was formally described as a new species in 1922 by German lichenologist Georg Hermann Zschacke as a species of ''Verrucaria''. Christine Keller, Cécile Gueidan, and Holger Thüs transferred it to the newly circumscribed genus ''Hydropunctaria'' in 2009. It is one of several aquatic lichens that are in this genus. The photobiont partner of ''Hydropunctaria rheitrophila'' is a yellow-green alga (class Xanthophyceae, genus ''Heterococcus ''Heterococcus'' is a genus of yellow-green algae Yellow-green algae or the Xanthophyceae (xanthophytes) are an important group of heterokont algae.

Zschacke
Georg Hermann Zschacke (27 May 1867–19 September 1937) was a German teacher and lichenologist. His specialty was the lichen family Verrucariaceae, about which he wrote many publications. Biography Zschake was born in Köthen on 27 May 1867. As a student he showed interest in the natural sciences, and started collecting specimens for his herbarium. From 1885 on he focussed his attention to cryptogams, i.e., lichens and mosses. In 1892 Zschake became a secondary school teacher (for mathematics and natural sciences) in Hecklingen and from 1898 in Bernburg. Zschake was surprised by the start of the war while on a collecting trip to Corsica in 1914. He was interned in the prison of Bastia, and later in the civil prison camp of the Corbara monastery near L'Île-Rousse. After becoming seriously ill, he was transferred to Switzerland in 1916 for therapy; this change of locales later led to Zschake writing a thesis on the lichen flora of the Davos valley.

Verrucariales
Verrucariales is an order of ascomycetous fungi within the subclass Chaetothyriomycetidae of the class Eurotiomycetes. Although most of the Verrucariales are lichenised, the family Sarcopyreniaceae consists of 11 species of lichenicolous (lichen-dwelling) fungi. Phylogenomic analysis suggests that the divergence between the lichenized Verrucariales and nonlichenized Chaetothyriales The Chaetothyriales are an order of ascomycetous fungi in the class Eurotiomycetes and within the subclass Chaetothyriomycetidae. The order was circumscribed in 1987 by mycologist Margaret Elizabeth Barr-Bigelow. Families and genera , Species ... occurred about 131 million years ago.

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''.

Xanthophyceae
Yellow-green algae or the Xanthophyceae (xanthophytes) are an important group of heterokont algae. Most live in fresh water, but some are found in marine and soil habitats. They vary from single-celled flagellates to simple colonial and filamentous forms. Xanthophyte chloroplasts contain the photosynthetic pigments chlorophyll ''a'', chlorophyll ''c'', β-carotene, and the carotenoid diadinoxanthin. Unlike other heterokonts, their chloroplasts do not contain fucoxanthin, which accounts for their lighter colour. Their storage polysaccharide is chrysolaminarin. Xanthophyte cell walls are produced of cellulose and hemicellulose. They appear to be the closest relatives of the brown algae. Classifications The species now placed in the Xanthophyceae were formerly included in the Chlorophyceae. In 1899, Lüther created the group Heterokontae for green algae with unequal flagella. Pascher (1914) included the Heterokontae in the Chrysophyta. In 1930, Allorge renamed the group as Xant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydropunctaria
''Hydropunctaria'' is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. The genus includes both aquatic and amphibious species, with members that colonise either marine or freshwater habitats. The type species, '' Hydropunctaria maura'', was formerly classified in the large genus ''Verrucaria''. It is a widely distributed species common to littoral zones. Including the type species, five ''Hydropunctaria'' lichens are considered marine species: ''H. adriatica'', ''H. amphibia'', ''H. aractina'', ''H. orae'', and ''H. oceanica''. Taxonomy ''Hydropunctaria'' was circumscribed in 2009 by Christine Keller, Cécile Gueidan, and Holger Thüs, with '' Hydropunctaria maura'' assigned as the type species. Description The thallus of ''Hydropunctaria'' is crustose, with a form ranging from continuous (more or less unbroken) to rimose or areolate. In some species the texture of the thallus is somewhat gelatinous. Documented thallu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cécile Gueidan
Cécile Gueidan is a mycologist and lichenologist who applies morphological and molecular biological methods to the origin and taxonomy of fungi that live in lichen symbioses and within rocks. Early life and education Gueidan began working on lichens during her Maitrise (1998) and DEA (1999) qualifications from Université Louis Pasteur and National Museum of Natural History, France. This included practical fieldwork experience with Claude Roux. She then studied molecular methods for lichen taxonomy at Duke University, USA and applied them to pyrenocarpous and Verrucariaceae lichens. Through combining morphological and molecular characters, she was able to refine the taxonomy of these groups. She was awarded her doctorate for this research in 2007. Career Her research focuses on the evolution and taxonomy of lichenised fungi and other ascomycete fungi. After gaining her doctorate, Gueidan carried out research at the Westerdijk Institute in the Netherlands on relationships be ...

Verrucaria
''Verrucaria'' is a genus of lichenized (lichen-forming) fungi in the family Verrucariaceae. Taxonomy The genus was circumscribed by German botanist Heinrich Adolph Schrader in 1794, with '' Verrucaria rupestris'' assigned as the type species. In his brief diagnosis of the genus, Schrader mentioned the more or less spherical (''subglobose''), closed ascomata, and the crustose thallus. The genus name is derived from the Latin word ''verruca'' (meaning "wart") and the suffix ''-aria'' (meaning "belonging to" or "possession"). Ecology As of 2015, there were 16 ''Verrucaria'' species classified as marine species: '' V. adguttata'', '' V. allantoidea'', '' V. ceuthocarpa'', '' V. corallensi'', '' V. ditmarsica'', '' V. erichsenii'', '' V. halizoa'', '' V. halochlora'', '' V. microsporoides'', '' V. paulula'', '' V. psychrophila'', '' V. sandstedei'', '' V. serpuloides'', '' V. sessilis'', '' V. subdiscreta'', ...
