Tricholoma Columbetta
''Tricholoma columbetta'', commonly known as dove-coloured tricholoma, is an edible mushroom of the large genus ''Tricholoma''. It is found in Europe, where it is eaten in France. Genus Elias Magnus Fries described the species in 1821 as ''Agaricus columbetta''. Paul Kummer placed it in the genus ''Tricholoma'' in 1871, within which it is classified in the Section ''Albata''. Description The fruit body (mushroom) is white or ivory-coloured, sometimes with a pale ochre tinge in the centre of the cap or pinkish, violet-blue or greenish spots. The cap is conical in young specimens, expanding to convex or flattish with a wavy margin, and is 4–10 cm in diameter. It can be a little sticky when wet. The centre of the cap may have a small boss or be depressed. The gills are adnate and widely spaced. The cylindrical stalk is 6–14 cm tall and 0,8–2 cm thick, and has no ring. The mushroom has a mealy smell, which is stronger when it is cut. The spore print is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö ( Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Kummer
Paul Kummer (22 August 1834 – 6 December 1912) was a minister, teacher, and scientist in Zerbst, Germany, known chiefly for his contribution to mycological nomenclature. Earlier classification of agarics by pioneering fungal taxonomist Elias Magnus Fries designated only a very small number of genera, with most species falling into '' Agaricus''. These few genera were divided into many ''tribi'' ("tribes"). In his 1871 work, ''Der Führer in die Pilzkunde'', Kummer raised the majority of Fries ''tribi'' to the status of genus, thereby establishing many of the generic names for agarics that are in use to this day. From 1857 to 1863, he worked as a private lecturer, then served as a curate A curate () is a person who is invested with the ''care'' or ''cure'' (''cura'') ''of souls'' of a parish. In this sense, "curate" means a parish priest; but in English-speaking countries the term ''curate'' is commonly used to describe clergy w ... in Zerbst (1863–1877).

Edible Mushroom
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 Mushroom poisoning, 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 mushroom hunting, harvested wild or fungiculture, cultivated. Easily cultivated and common wild mushrooms are often available in Market (place), markets, and those that are more difficult to obtain (such as the prized Tuber (genus), truffle, matsutake, and Morchella, morel) may be collected on a smaller scale by private gatherers. Some preparations may render ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricholoma
''Tricholoma'' is a genus of fungus that contains many fairly fleshy white-spored gilled mushrooms which are found worldwide generally growing in woodlands. These are ectomycorrhizal fungi, existing in a symbiotic relationship with various species of coniferous or broad-leaved trees. The generic name derives from grc, τριχο-, tricho-, hair and grc, λῶμα, loma, fringe, border although only a few species (such as '' T. vaccinum'') have shaggy caps which fit this description. The most sought out species are the East Asian '' Tricholoma matsutake'', also known as ''matsutake'' or ''songi'', and the North American '' Tricholoma magnivelare'' species complex, also known as "ponderosa mushroom", "American matsutake", or " pine mushroom". Others are safe to eat, such as ''Tricholoma terreum'', but there are a few poisonous members, such as '' T. pardinum'', '' T. tigrinum'' and '' T. equestre''. Many species originally described within Tricholoma have since been moved to ... [...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 ...

Lamella (mycology)
In mycology, a lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, ''Lactarius'' species typically seep latex from their gills. It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolved gills i ... [...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 unive ...

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 ...

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 ...

Entoloma Lividum
''Entoloma sinuatum'' ( commonly known as the livid entoloma, livid agaric, livid pinkgill, leaden entoloma, and lead poisoner) is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of ''Entoloma lividum'' or ''Rhodophyllus sinuatus''. The largest mushroom of the genus of pink-spored fungi known as ''Entoloma'', it is also the type species. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands, sometimes in the form of fairy rings. Solid in shape, they resemble members of the genus ''Tricholoma''. The ivory to light grey-brown cap is up to across with a margin that is rolled inward. The sinuate gills are pale and often yellowish, becoming pink as the spores develop. The thick whitish stem has no ring. When young, it may be mistaken for the edible St George's mushroom (''Calocybe gambosa'') or the miller (''Clitopilus prunulus''). It has ...

Quercus
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably '' Lithocarpus'' (stone oaks), as well as in those of unrelated species such as '' Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth mar ...
