Suillus Subacerbus
''Suillus subacerbus'' is a species of bolete fungus in the family Suillaceae. Species description, Described as new to science in 1968 by mycologist Robert Francis Ross McNabb, it is found in New Zealand, where it grows in association with ''Pinus radiata''. Description Its basidiocarp, fruitbodies produce convex to flattened pileus (mycology), caps measuring in diameter. The cap colour is quite variable, ranging from creamy yellow to olive grey initially, later becoming ochre, brown, or reddish orange (sometimes streaked) as the fruitbody matures. The pore surface on the cap underside is dull yellow, later becoming darker. Pores are small and angular, about 0.75–1 mm in diameter. The stipe (mycology), stipe measures long by up to wide, and lacks a annulus (mycology), ring. The spore print is yellowish brown. Basidiospore, Spores are smooth elliptical, with typical dimensions of 7.8–9.1 by 3.0–3.6 micrometre, µm. The complex of species that include ''Suillus ...

Robert Francis Ross McNabb
Robert Francis Ross McNabb (11 December 1934 – 14 December 1972) was a New Zealand mycologist. He was born in Kawakawa, and attended local schools in his youth, including Whangarei Boys' High School and Southland Boys' High School. He received a BSc degree from the University of Otago in 1956, and two years later an MSc for his work on mycorrhizae morphology in native New Zealand plants. In 1961, having been awarded a National Research Fellowship the year before, McNabb left New Zealand for the UK to study with Cecil Terence Ingold at Birkbeck College. McNabb earned a PhD in 1963; his thesis was titled "Taxonomic studies in the Dacrymycetaceae". He was jointly awarded the Hamilton Memorial Prize in 1966 from The Royal Society of New Zealand, the same year he was appointed to the editorial board of the ''New Zealand Journal of Botany''. Most of McNabb's later publications, largely published in this journal, were about fungal taxonomy. Fungus species named in honor of McNabb inclu ...

It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. Method A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, i ...

Suillus
''Suillus'' is a genus of basidiomycete fungi in the family Suillaceae and order Boletales. Species in the genus are associated with trees in the pine family (Pinaceae), and are mostly distributed in temperate locations in the Northern Hemisphere, although some species have been introduced to the Southern Hemisphere. Taxonomy The genus ''Suillus'' was first defined by Pier Antonio Micheli in his 1729 work ''Nova plantarum genera'', however it is not valid as it predates the 1753 start of Linnean taxonomy. Fries sanctioned the use by British botanist Samuel Frederick Gray in the first volume of his 1821 work ''A Natural Arrangement of British Plants''. Setting ''Suillus luteus'' as the type species, he described the genus as those mushrooms with a centrally placed stipe, a distinct ring, a circular cap, and tubes that are stuck together. They have been commonly called "slippery jacks" because the cap of the fruit body is sometimes slimy. The genus name is derived from the Lat ...

Suillus Pungens
''Suillus pungens'', commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus ''Suillus''. The fruit bodies of the fungus have slimy convex caps up to wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stem (stipe) up to long, and thick. On the underside on the cap is the spore-bearing tissue consisting of minute vertically arranged tubes that appear as a surface of angular, yellowish pores. The presence of milky droplets on the pore surface of young individuals, especially in humid environments, is a characteristic feature of this species. ''S. pungens'' can usually be distinguished from other similar ''Suillus'' species by differences in distribution, odor and taste. The mushroom is considered edible, but not ...

Suillus Granulatus
''Suillus granulatus'' is a pored mushroom of the genus ''Suillus'' in the family Suillaceae. It is similar to the related '' S. luteus'', but can be distinguished by its ringless stalk. Like ''S. luteus'', it is an edible mushroom that often grows in a symbiosis ( mycorrhiza) with pine. It has been commonly known as the weeping bolete, or the granulated bolete. Previously thought to exist in North America, that species has now been confirmed to be the rediscovered '' Suillus weaverae''. Taxonomy ''Suillus granulatus'' was first described by Carl Linnaeus in 1753 as a species of ''Boletus''. It was given its current name by French naturalist Henri François Anne de Roussel when he transferred it to ''Suillus'' in 1796. ''Suillus'' is an ancient term for fungi, and is derived from the word "swine". ''Granulatus'' means "grainy" and refers to the glandular dots on the upper part of the stem. However, in some specimens the glandular dots may be inconspicuous and not dark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer ( American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix " micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm � ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus '' Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration ...

Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guide A field guide is a book designed to help the reader identify wildlife (flora or fauna) or other objects of natural occurrence (e.g. rocks and minerals). It is generally designed to be brought into the " field" or local area where such objects e ...s and on identification websites. Ring descriptions The way in which the structure and appea ...

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 ...

Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus or cortina) or unive ...

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 ...
