Austroboletus Mutabilis
''Austroboletus mutabilis'' is a species of bolete fungus found in northern Australia. Described as new to science in 2006, it grows in dry sclerophyll woodlands. This bolete is characterised by its colour change—from deep red to orange and, finally, to yellow—that occurs in the cap. Almost no other Bolete goes through such a dramatic colour change as this species and this change may occur as a consequence of time, exposure to sunlight and/or local humidity. Microscopically, the suprahilar plage on spores of A. mutabilis is conspicuous and appears to lack the obvious ornamentation present on the rest of the spore. While the plage appears smooth under the light microscope, scanning electron micrography shows a large, irregular pit or erosion of that region which seems to develop with maturation. Austroboletus mutabilis was identified as a new species of ''Austroboletus'' by Roy Halling, Todd Osmundson and Maria Alice Neves in a 2006 article and is known to grow at a few sit ...

Austroboletus Mutabilis By Ray Palmer 1
''Austroboletus'' is a genus of fungi in the family Boletaceae. The widely distributed genus contains 28 species that form mycorrhizal relationships with plants. Taxonomy E. J. H. Corner originally defined ''Austroboletus'' as a subgenus of ''Boletus'' in his 1972 work ''Boletus in Malaysia'', before it was raised to genus level in 1979 by mycologist Carl B. Wolfe. The type species is ''Austroboletus dictyotus'', a fungus originally described by Karel Bernard Boedijn in 1960 as a member of genus ''Porphyrellus''. The generic name ''Austroboletus'' means "southern bolete". In a 2014 molecular genetics study, Wu and colleagues defined 22 clades within the Boletaceae. They found the genus as understood to be polyphyletic – composed of two distinct lineages. One with pitted stipes, which remained as ''Austroboletus'', while those with smoother stipes were moved to ''Veloporphyrellus''. They delineated a subfamily Austroboletoideae, which contained genera with pitted spores, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp ( fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium ( hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various '' Amanita'' species and boletes. Some, such as the parasol mushroom, have distinct bosses or umbos and are described as '' umbonate''. An umbo is a knobby protrusion at th ...

Roy Halling
Roy Edward Halling (born December 31, 1950, in Perry, Iowa) is an American mycologist. Halling specializes in the study of mushroom-forming fungi, especially the taxonomy, ecology, and systematics of the Boletineae, a suborder of the Boletales, and is widely published in this area. He is currently emeritus curator of mycology at the New York Botanical Garden, and was an adjunct professor at Columbia University. Halling received his master's degree from San Francisco State University in 1976, with a thesis titled "The Boletaceae of the Sierra Nevada", under the supervision of Harry Delbert Thiers. His PhD was from the University of Massachusetts Amherst, in 1980 with a dissertation titled "The genus ''Collybia'' in New England. His supervisor was Howard E. Bigelow. Halling has served as the associate editor of the journal ''Brittonia'' (1984–1989), the managing editor of ''Mycologia ''Mycologia'' is a peer-reviewed scientific journal that publishes papers on all aspects of the f ...

Bolete
{{refimprove, date=July 2020 A bolete is a type of mushroom, or fungal fruiting body. It can be identified thanks to a unique mushroom cap. The cap is clearly different from the stem. On the underside of the cap there is usually a spongy surface with pores, instead of the gills typical of mushrooms. However, there are some boletes that are gilled, such as species of '' Chroogomphus'', '' Gomphidius'', ''Paxillus'', '' Phylloporus'' and '' Hygrophoropsis aurantiaca''. "Bolete" is the English common name In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrast ... for fungus species whose mushroom caps have this appearance. The boletes are classified in the order Boletales. Not all members of the order Boletales are boletes. The micromorphology and molecular phylogeny of the order ...

Fungus
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Australia
The unofficial geographic term Northern Australia includes those parts of Queensland and Western Australia north of latitude 26° and all of the Northern Territory. Those local government areas of Western Australia and Queensland that lie partially in the north are included. Although it comprises 45% of the total area of Australia, Northern Australia has only 5% of the Australian population (1.3 million in 2019). However, it includes several sources of Australian exports, being coal from the Great Dividing Range in Queensland/New South Wales and the natural gas and iron ore of the Pilbara region in WA. It also includes major natural tourist attractions, such as Uluru (Ayers Rock), the Great Barrier Reef and the Kakadu National Park. Geography and climate Almost all of Northern Australia is a huge ancient craton that has not experienced geological upheaval since the end of the Precambrian. The only exception to this generalisation is the Wet Tropics of northern Queenslan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sclerophyll
Sclerophyll is a type of vegetation that is adapted to long periods of dryness and heat. The plants feature hard leaves, short internodes (the distance between leaves along the stem) and leaf orientation which is parallel or oblique to direct sunlight. The word comes from the Greek ''sklēros'' (hard) and ''phyllon'' (leaf). The term was coined by A.F.W. Schimper in 1898 (translated in 1903), originally as a synonym of xeromorph, but the two words were later differentiated. Sclerophyllous plants occur in many parts of the world, but are most typical of areas with low rainfall or seasonal droughts, such as Australia, Africa, and western North and South America. They are prominent throughout Australia, parts of Argentina, the Cerrado biogeographic region of Bolivia, Paraguay and Brazil, and in the Mediterranean biomes that cover the Mediterranean Basin, California, Chile, and the Cape Province of South Africa. In the Mediterranean basin, holm oak, cork oak and olives are ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Queensland
North Queensland or the Northern Region is the northern part of the Australian state of Queensland that lies just south of Far North Queensland. Queensland is a massive state, larger than many countries, and its tropical northern part has been historically remote and undeveloped, resulting in a distinctive regional character and identity. Townsville is the largest urban centre in North Queensland, leading it to be regarded as an unofficial capital. The region has a population of 231,628 and covers . Geography There is no official boundary that separates North Queensland from the rest of the state. Unofficially it is usually considered to have a southern border beginning south of the Mackay Region southern boundary, but historically it has been as far south as Rockhampton. To the north is the Far North Queensland region, centred on Cairns and out west is the Gulf Country. A coastal region centred on its largest settlement is the city of Townsville. The city is the locat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
