Cryptothecia Fuscopunctata
''Cryptothecia'' is a genus of white to greenish crustose lichens that grow on bark, wood, or leaves. in tropical or subtropical areas worldwide. It has a conspicuous prothallus that develops around its periphery which can be bright red in some species, hence the common name wreath lichen. The main vegetative body (thallus) lacks a cortex (ecorticate and is often immersed in the substrate or byssoid (whispy, like teased wool). The medulla is white, well defined, and often peppered with calcium oxalate crystals. Ascomata are not well defined, being cushions of soft white mycelium immersed in the medullary tissue, hence the name from the Greek ''krypto'' = "to conceal" and ''theke'' = "a container or sheath". There are about 45 described species in the genus according to one source, and 75 species according to another. The genus is in the family Arthoniaceae. It contains '' Trentepohlia'', a green alga, as its photobiont partner. Two species have been described in North America.Br ...

James Stirton
James Stirton (1833, Coupar Angus, Perthshire – 14 January 1917, Glasgow) was a Scottish physician and one of Scotland's leading experts on cryptogamic botany. His investigations in bryology and lichenology earned him a world-wide reputation. Biography Stirton taught mathematics from 1856 to 1858 at the Merchiston Castle School in Edinburgh. At the University of Edinburgh he graduated in 1857 L.R.C.P.Edin and in 1858 M.D.Edin. Soon after acquiring his M.D. he moved to Glasgow and established an extensive practice in obstetrics and gynaecology. In 1876 Stirton was appointed a lecturer in gynaecology at the Glasgow Royal Infirmary, where for many years he had charge of the gynaecological wards. In 1889 he became a professor of midwifery at Anderson’s College Medical School and held the professorship for about fifteen years. Stirton made many visits to the Scottish mountains to investigate lichens and mosses and there discovered numerous species that were previously undescribed. ...

Ascomata
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks of ...

Cryptothecia Austrocoreana
''Cryptothecia austrocoreana'' is a species of crustose and corticolous (bark-dwelling) lichen in the family Arthoniaceae. Found in South Korea, it was formally described as a new species in 2017 by Jung-Jae Woo, László Lőkös, Edit Farkas, and Jae-Seoun Hur. The type specimen was collected by the first author near Seonamsa (Suncheon, Jeollanam Province) at an altitude of ; here it was found growing on the bark of '' Meliosma myriantha''. It also grows on the bark of ''Carpinus tschonoskii''. The lichen is only known to occur at the type locality. The specific epithet ''austrocoreana'' refers to the southern part of South Korea. Lichen products found in ''Cryptothecia austrocoreana'' include barbatic acid as a major constituent, minor amounts of atranorin, and trace amounts of chloroatranorin. Only six other species of genus ''Cryptothecia ''Cryptothecia'' is a genus of white to greenish crustose lichens that grow on bark, wood, or leaves. in tropical or subtropical are ...

Cryptothecia Atropunctata
''Cryptothecia'' is a genus of white to greenish crustose lichens that grow on bark, wood, or leaves. in tropical or subtropical areas worldwide. It has a conspicuous prothallus that develops around its periphery which can be bright red in some species, hence the common name wreath lichen. The main vegetative body (thallus) lacks a cortex (ecorticate and is often immersed in the substrate or byssoid (whispy, like teased wool). The medulla is white, well defined, and often peppered with calcium oxalate crystals. Ascomata are not well defined, being cushions of soft white mycelium immersed in the medullary tissue, hence the name from the Greek ''krypto'' = "to conceal" and ''theke'' = "a container or sheath".

Cryptothecia Rubrocincta
''Cryptothecia rubrocincta'' is a species of lichen in the fungal family Arthoniaceae. The species is distributed in subtropical and tropical locations throughout the southeastern United States, as well as Central and South America, and has been collected infrequently in a few locales in Africa. The body of the lichen forms continuous, circular crust-like patches on dead wood, readily recognizable by the prominent red pigment. The older, central region is covered with red, spherical to cylindrical granules. Moving outwards from the center, zones of color may be distinguished, the first gray-green, the second white, and finally a bright red cottony rim. The red and green colors of this unmistakable woodland lichen give the appearance of a Christmas wreath, suggestive of its common North American name, the Christmas (wreath) lichen. The red pigment, called chiodectonic acid, is one of several chemicals the lichen produces to help tolerate inhospitable growing conditions. Taxonomy ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Green Alga
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organ ...
