Hypocreopsis
''Hypocreopsis'' is a genus of ascomycete fungi that form stromata on the stems of trees and shrubs. The stromata are orange-brown and consist of radiating, perithecial lobes. Species The genus includes three species: *''Hypocreopsis amplectens'' *'' Hypocreopsis lichenoides'' *''Hypocreopsis rhododendri'' The species are macroscopically similar, other than the fact that ''H. lichenoides'' may develop brown mealy patches of conidia on the surface of its lobes. The species may however be distinguished by their spore morphology: ''H. lichenoides'' has ellipsoid to short-fusiform, 1-septate spores; ''H. rhododendri'' has globose, 0-1 septate spores, and ''H. amplectens'' has cylindric, 2-3 septate spores. Distribution ''Hypocreopsis amplectens'' and ''H. rhododendri'' are restricted to an oceanic climate. ''Hypocreopsis rhododendri'' occurs on the western fringe of Europe, and has also been recorded historically from the Appalachian mountains in the eastern USA, and '' H. amplecten ...

Hypocreopsis Rhododendri
''Hypocreopsis rhododendri'' is an ascomycete fungus. It is commonly known as hazel gloves due to the resemblance of its orange-brown, radiating lobes to rubber gloves, and because it is found on hazel (''Corylus avellana'') stems. Distribution ''Hypocreopsis rhododendri'' is found on the hyperoceanic west coasts of Britain and Ireland, in the Atlantic Pyrenees in south western France, and in the Appalachian mountains in the eastern United States. Habitat In the Appalachian mountains, ''H. rhododendri'' was originally found growing on ''Rhododendron maximum'', and was subsequently found on ''Kalmia latifolia'' and ''Quercus'' sp. In Europe, ''H. rhododendri'' is found in Atlantic hazel woodland, mainly on hazel stems. It has never been found on ''Rhododendron'' species. Host Although ''H. rhododendri'' is found on woody stems, it has been suggested that it is not a wood-decay fungus A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, caus ...

Hypocreaceae
The Hypocreaceae are a family (biology), family within the class Sordariomycetes. Species of Hypocreaceae are usually recognized by their brightly colored, perithecial Ascocarp, ascomata, typically yellow, orange or red. The family was proposed by Giuseppe De Notaris in 1844. According to the ''Dictionary of the Fungi'' (10th edition, 2008), the family has 22 genera and 454 species. Genera *''Acrostalagmus'' *''Aphysiostroma'' *''Cladobotryum'' *''Gliocladium'' *''Hypocrea'' *''Hypocreopsis'' *''Hypomyces'' *''Mycogone'' *''Podostroma'' *''Protocrea'' *''Rogersonia'' *''Sarawakus'' *''Sepedonium'' *''Sphaerostilbella'' *''Sporophagomyces'' *''Stephanoma'' *''Trichoderma'' References {{Taxonbar, from=Q3144255 Hypocreaceae, Ascomycota families Taxa named by Giuseppe De Notaris Taxa described in 1844 ...

Ascospore
An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. ''Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. ''Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some ''Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bourrelet ...

Polar Climate
The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month in a polar climate has an average temperature of less than . Regions with polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles, and in this case, winter days are extremely short and summer days are extremely long (could last for the entirety of each season or longer). A polar climate consists of cool summers and very cold winters, which results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice. It is identified with the letter E in the Köppen climate classification. Subtypes There are two types of polar climate: ET, or tundra climate; and EF, or ice cap climate. A tundra climate is characterized by having at least one month whose average temperature is above , while an ice cap climate has no months averaging above . In a tundra climate, even coniferous trees cannot grow, but o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Climate
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 the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. M ...

Globose
A sphere () is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance from a given point in three-dimensional space.. That given point is the centre of the sphere, and is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians. The sphere is a fundamental object in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry. Bubbles such as soap bubbles take a spherical shape in equilibrium. The Earth is often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy. Manufactured items including pressure vessels and most curved mirrors and lenses are based on spheres. Spheres roll smoothly in any direction, so most balls used in sports and toys are spherical, as are ball bearings. Basic terminology As mentioned earlier is the sphere's r ...

Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue. *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscular sep ...
