Boletus Innixus
''Aureoboletus innixus'' is a species of bolete fungus in the family Boletaceae. Found in eastern North America, it was first described scientifically by Charles Christopher Frost in 1874, from collections made in New England. An edible mushroom, the convex cap grows to wide and is dull reddish brown to yellow brown. The stem Stem or STEM may refer to: Plant structures * Plant stem, a plant's aboveground axis, made of vascular tissue, off which leaves and flowers hang * Stipe (botany), a stalk to support some other structure * Stipe (mycology), the stem of a mushro ... is long by thick, but often swollen at the apex with a tapered base. It has a bright yellow pore surface when young that dulls in color when mature. There are about 1 to 3 pores per mm when young, but they expand as they mature to about 2 mm wide. The spore print is olive-brown, and the spores are ellipsoid, smooth, and measure 8–11 by 3–5 um. The mushroom is often confused with the sim ...

Charles Christopher Frost
Charles Christopher Frost (November 11, 1805 – March 16, 1880) was an American mycologist. He described several species of fungi from the New England area of the United States. In one paper, Frost described 22 new species of boletes, and he was later credited with the discovery of three additional species. His personal herbarium of specimens were given to the University of Vermont in 1902. Portions of his collection today are distributed between the Farlow Herbarium at Harvard University, the New York State Museum, the Bell Museum of Natural History, and the Buffalo Museum of Science. Early life Frost was born in Brattleboro, Vermont, on November 11, 1805. His parents were shoemaker James Frost and Elizabeth Stewart, daughter of an officer in the American Revolution. When he was fifteen, Frost left school after being hit with a ruler by a teacher, and assisted his father with his business. Although Frost had developed a prior interest in the natural sciences, his interest in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spores
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new spor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Described In 1874
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a 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 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 group of related organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edible Fungi
Edible mushrooms are the fleshy and edible fruit bodies of several species of macrofungi (fungi which bear fruiting structures that are large enough to be seen with the naked eye). They can appear either below ground (hypogeous) or above ground (epigeous) where they may be picked by hand. Edibility may be defined by criteria that include absence of poisonous effects on humans and desirable taste and aroma. Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor. Edible mushrooms include many fungal species that are either harvested wild or cultivated. Easily cultivated and common wild mushrooms are often available in markets, and those that are more difficult to obtain (such as the prized truffle, matsutake, and morel) may be collected on a smaller scale by private gatherers. Some preparations may render certain poisonous mushrooms fit for consumption. Before assuming that any wild mushroom is e ...

Aureoboletus Auriporus
''Aureoboletus auriporus'', is a species of bolete fungus in the family Boletaceae that is found in Europe and North America. It was originally described in 1872 by American mycologist Charles Horton Peck, who called it ''Boletus auriporus''. Zdenek Pouzar transferred it to the genus '' Aureoboletus'' in 1957. The species is edible, and could be confused with (the also edible) ''Xerocomus illudens ''Xerocomus illudens'' is a species of bolete fungus in the family Boletaceae.

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 – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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, it ...

Rolf Singer
Rolf Singer (June 23, 1906 – January 18, 1994) was a Germany, German-born mycologist and one of the most important Taxonomy (biology), taxonomists of gilled mushrooms (agarics) in the 20th century. After receiving his Ph.D. at the University of Vienna in 1931 he worked in Munich. By 1933, however, Singer left Germany for Vienna due to the political deterioration in Germany. There he met his wife, Martha Singer. From Vienna, Singer and his wife went to Barcelona, Spain, where Singer was appointed assistant professor at the Autonomous University of Barcelona. Persecution by the Spanish authorities on behalf of the Germany, German government forced Singer to leave Spain for France in 1934. After a fellowship at the Museum d'Histoire Naturelle in Paris, Singer again moved, this time to Leningrad, where he was Senior Scientific Expert at the Botanical Garden of the Academy of Sciences of the USSR. During his time at the Academy, Singer made many expeditions to Siberia, the Altai Mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 universal ve ...

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 the center of th ...
