Pyrenula Cinnabarina
''Pyrenula cinnabarina'' is a species of corticolous (bark-dwelling), crustose lichen in the family Pyrenulaceae. Found in Brazil, this species is notable for its dark carmine-red thallus and its known as ascomata (fruiting bodies), which are grouped in clusters of 5–30. The , which are the spores produced within the asci, are 3- septate, meaning they are divided into four sections, and measure 12–15 μm by 6–7 μm. The type specimen of ''Pyrenula cinnabarina'' was collected from Catimbau National Park in Buíque, Pernambuco, Brazil, at an elevation of about . The thallus is thin, granular, and dark carmine red, lacking pseudocyphellae (small pores on the surface) and a (a border around the thallus). The ascomata are superficial (situated on the surface), (roughly spherical), 0.2–0.35 mm in diameter, and clustered in groups with fused walls but separate ostioles (openings). The walls of the ascomata are completely (blackened), and the ostioles are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
André Aptroot
André Aptroot (Heemskerk, 1961) is a Dutch mycologist and lichenologist. In 1993 he did his PhD at the University of Utrecht under the supervision of Robbert Gradstein (nl). His dissertation was titled "Systematic studies on pyrenocarpous lichens and related fungi". He specializes in fungi and lichens on which he has several hundreds of publications to his name. He has worked as curator at Centraalbureau voor Schimmelcultures (now Westerdijk Institute). Aptroot is the founder of the Consultancy for Bryology and Lichenology, which is located in Soest where there is a herbarium with a collection of lichens mainly from the Netherlands and the tropics. From 2008 he has been collection manager at Pinetum Blijdenstein (nl) in Hilversum. He is a member of the International Association for Lichenology and the American Bryological and Lichenological Society. He is a visiting professor at the Federal University of Mato Grosso do Sul in Campo Grande, Brazil. Because of Aptroot's bro ...

Ostiole
An ''ostiole'' is a small hole or opening through which algae or fungi release their mature spores. The word is a diminutive of "ostium", "opening". The term is also used in higher plants, for example to denote the opening of the involuted syconium (fig inflorescence) through which fig wasps enter to pollinate and breed. Sometimes a stoma In botany, a stoma (from Greek ''στόμα'', "mouth", plural "stomata"), also called a stomate (plural "stomates"), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange.

List Of Pyrenula Species
The genus '' Pyrenula'' consists of crustose lichens that usually grow on smooth, shaded bark. About 750 taxa have been named in the genus, although the majority of these names have been excluded from the genus as they have been transferred to other genera, or are considered synonyms. In his world key to the ''Pyrenula'' species, published in 2012, André Aptroot accepted 169 species, including 7 not yet formally described. , Species Fungorum accepts 168 species of ''Pyrenula''.

Caatinga
Caatinga (, ) is a type of semi-arid tropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" is a Tupi word meaning "white forest" or "white vegetation" (''caa'' = forest, vegetation, ''tinga'' = white). The Caatinga is a xeric shrubland and thorn forest, which consists primarily of small, thorny trees that shed their leaves seasonally. Cacti, thick-stemmed plants, thorny brush, and arid-adapted grasses make up the ground layer. Most vegetation experiences a brief burst of activity during the three-month long rainy season. Caatinga falls entirely within earth's tropical zone and is one of 6 major ecoregions of Brazil. It covers 850,000 km², nearly 10% of Brazil's territory. It is home to 26 million people and over 2000 species of plants, fish, reptiles, amphibians, birds, and mammals. The Caatinga is the only exclusively Brazilian biome, which means that a large part of its biological heritage cannot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultraviolet
Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nanometer, nm (with a corresponding frequency around 30 Hertz, PHz) to 400 nm (750 Hertz, THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionization, ionize atoms, it can cause chemical reactions and causes many substances to glow or fluorescence, fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules. Short-wave ultraviolet light damages DNA and sterilizes surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pycnidia
A pycnidium (plural pycnidia) is an asexual fruiting body produced by mitosporic fungi, for instance in the order Sphaeropsidales ( Deuteromycota, Coelomycetes) or order Pleosporales (Ascomycota, Dothideomycetes). It is often spherical or inversely pearshaped ( obpyriform) and its internal cavity is lined with conidiophores. When ripe, an opening generally appears at the top, through which the pycnidiospore {{Short pages monitor [Baidu] |
Pseudocyphella
Pseudocyphellae (singular ''pseudocyphella'') are structures in lichens that appear as tiny pores on the outer surface (the cortex of the lichen. They are caused when there is a break in the cortex of the lichen, and the medullary hyphae extend to the surface. Pseudocyphellae are the same colour as the medulla of the lichen, which is generally white, but can be yellow in some species of ''Pseudocyphellaria'' and in ''Bryoria fremontii''. The presence/absence, abundance, colour, and shape of pseudocyphellae can all be diagnostic features used to identify different species. They facilitate gas exchange through the surface of the lichen, and may provide an adaptive advantage in temperate In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout t ... environments. References *Brodo, I. M., S. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
