Russula Turci
''Russula turci'' is a common, edible, '' Russula'' mushroom, found under pines and spruces, on sandy soil and clay. Description The cap is flat when young, matures to be somewhat funnel shaped, dark amethyst-violet to brownish pink. The margin is paler and noticeably matt. The cap grows up to 8 cm in diameter. The gills are cream to light ochre, rather crowded and connected at the base by cross veins. The spores are ochre. The stem is white and evenly thick. The flesh is white, and the base of the stem has a distinct smell of iodine. Similar species The rare '' Russula azurea'' also has a purple cap and grows beneath spruces. ''Russula amethystina ''Russula amethystina'' is a conspicuous mushroom, which appears sporadically from mid-summer until the autumn under spruce and fir trees. In Northern Europe, it is very rare.

Giacomo Bresadola
Giacomo Bresadola ( Mezzana, Trento; often given as Giacopo) 14 February 1847 – Trento 9 June 1929) was an eminent Italian mycologist. Fungi he named include the deadly ''Lepiota helveola'' and ''Inocybe patouillardii'', though the latter is now known as '' Inosperma erubescens'' as this latter description predated Bresadola's by a year. He was a founding member of the ''Société mycologique de France'' (Mycology Society of France). Life Bresadola was born in 1847 into a farming family in Trent, then an Austrian possession. From a very early age, he showed an interest in botany. After attending elementary school at Mezzana, he was sent by his father to Cloz in the Val di Non at the age of nine to continue his studies with his uncle who was a priest. His uncle, however, considered him too rambunctious and quickly sent him home again. In 1857, his father moved to Montichiari in Brescia to become a bronze merchant. At twelve years of age, he left to study at the technical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russula
''Russula'' is a very large genus composed of around 750 worldwide species of ectomycorrhizal mushrooms. They are typically common, fairly large, and brightly colored – making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include usually brightly coloured caps, a white to dark yellow spore print, brittle, attached gills, an absence of latex, and absence of partial veil or volva tissue on the stem. Microscopically, the genus is characterised by the amyloid ornamented spores and flesh (trama) composed of spherocysts. Members of the related genus ''Lactarius'' have similar characteristics but emit a milky latex when their gills are broken. The genus was described by Christian Hendrik Persoon in 1796. Taxonomy Christian Hendrik Persoon first circumscribed the genus ''Russula'' in his 1796 work ''Observationes Mycologicae'', and considered the defining characteristics to be the fleshy fruit bodies, depre ...

Russula Amethystina
''Russula amethystina'' is a conspicuous mushroom, which appears sporadically from mid-summer until the autumn under spruce and fir trees. In Northern Europe, it is very rare. It is not easy to distinguish from similarly coloured ''Russula'' species, and practically identical to '' Russula turci''. Description The cap ranges from 3 to 12 cm in diameter and varies in colour between violet, lilac, wine-red and wine-red-brown. The cap skin can be pulled off from the edge, right to the centre. The gills are from cream to bright yellow. The spores are yellow, subglobose, with small warts. The spore print is cream to light orange in color. The hollow stipe ranges from 3 to 6 cm in length and 1 to 2 cm in width; it is initially white, later becoming yellowish or brownish. Similar species include '' Russula turci'', which may smell like iodine near the base of the stalk; otherwise it can only be distinguished by microscopic differences in spore In biology, a spore is a unit ...

Abies Alba
''Abies alba'', the European silver fir or silver fir, is a fir native to the mountains of Europe, from the Pyrenees north to Normandy, east to the Alps and the Carpathians, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, and south to Italy, Bulgaria, Kosovo, Albania and northern Greece; it is also commonly grown on Christmas tree plantations in the North East region of North America spanning New England in the US to the Maritime provinces of Canada. Description ''Abies alba'' is a large evergreen coniferous tree growing to tall and with a trunk diameter up to . The largest measured tree was tall and had a trunk diameter of . It occurs at altitudes of (mainly over ), on mountains with rainfall over per year. The leaves are needle-like, flattened, long and wide by thick, glossy dark green above, and with two greenish-white bands of stomata below. The leaf is usually slightly notched at the tip. The cones are long and broad, with about 150-200 scale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fungi Of Europe
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 ... [...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 mushro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Giacomo Bresadola
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
