Amanita Lanei
''Amanita calyptroderma'' also known as coccora, coccoli or the Pacific amanita, is a white-spored mushroom that fruits naturally in the coastal forests of the western United States during the fall and winter and spring. Description This mushroom's cap is about 10–25 cm in diameter, usually orange-brown in color (but sometimes white), and partially covered by a thick white patch of universal veil. It has white, close gills. Its cream-colored stalk is about 10–20 cm in length and 2–4 cm in width, adorned with a partial veil. It has a partially hollow stem (filled with a stringy white pith), and a large, sacklike volva at the base of the stalk. The spores of this species, which are white, do not change color when placed in a solution of Melzer's reagent, and thus are termed inamyloid. This characteristic in combination with the skirt-like annulus and absence of a bulb at the base of the stalk place this mushroom in the section ''Caesareae''. Distribution and habitat This m ...

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, ''Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi ( Basidiomycota, Agaricomycetes) that have a stem ( stipe), a cap ( pileus), and gills (lamellae, sing. lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as "bolete", "puffball", "stinkhorn", and " morel", and gilled mushrooms themselves are often called "agarics" in refere ...

Madrone
''Arbutus'' is a genus of 12 accepted speciesAct. Bot. Mex no.99 Pátzcuaro abr. 2012.''Arbutus bicolor''/ref> of flowering plants in the family Ericaceae, native to warm temperate regions of the Mediterranean, western Europe, the Canary Islands and North America. The name ''Arbutus'' was taken from Latin, where it referred to ''Arbutus unedo''. Description ''Arbutus'' are small trees or shrubs with red flaking bark and edible red berries.Mabberley, D. J. 1997. ''The plant book: A portable dictionary of the vascular plants''. Cambridge University Press, Cambridge. Fruit development is delayed for about five months after pollination, so that flowers appear while the previous year's fruit are ripening. Peak flowering for the genus is in April with peak fruiting in October. History The smooth wood of the tree is mentioned by Theophrastus in his ''Enquiry into Plants'' (''Historia Plantarum'') as formerly being used to make weaving spindles.

Amanita Caesarea
''Amanita caesarea'', commonly known as Caesar's mushroom, is a highly regarded edible mushroom in the genus ''Amanita'', native to southern Europe and North Africa. While it was first described by Giovanni Antonio Scopoli in 1772, this mushroom was a known favorite of early rulers of the Roman Empire. It has a distinctive orange cap, yellow gills and stipe. Organic acids have been isolated from this species. Similar orange-capped species occur in North America and India. It was known to and valued by the Ancient Romans, who called it ''Boletus'', a name now applied to a very different type of fungus. Although it is edible, the Caesar's mushroom is closely related to the psychoactive fly agaric, and to the deadly poisonous death cap and destroying angels. Taxonomy and naming ''Amanita caesarea'' was first described by Italian mycologist Giovanni Antonio Scopoli in 1772 as ''Agaricus caesareus'', before later being placed in ''Amanita'' by Persoon in 1801.

Amanita Vernicoccora
The genus ''Amanita'' contains about 600 species of agarics, including some of the most toxic known mushrooms found worldwide, as well as some well-regarded edible species. This genus is responsible for approximately 95% of the fatalities resulting from mushroom poisoning, with the death cap accounting for about 50% on its own. The most potent toxin present in these mushrooms is α-Amanitin. The genus also contains many edible mushrooms, but mycologists discourage mushroom hunters, other than experts, from selecting any of these for human consumption. Nonetheless, in some cultures, the larger local edible species of ''Amanita'' are mainstays of the markets in the local growing season. Samples of this are '' Amanita zambiana'' and other fleshy species in central Africa, '' A. basii'' and similar species in Mexico, '' A. caesarea'' and the "Blusher" '' Amanita rubescens'' in Europe, and '' A. chepangiana'' in South-East Asia. Other species are used for colouring sauces, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amanita Ocreata
''Amanita ocreata'', commonly known as the death angel, destroying angel, angel of death or more precisely western North American destroying angel, is a deadly poisonous basidiomycete fungus, one of many in the genus ''Amanita''. Occurring in the Pacific Northwest and California floristic provinces of North America, ''A. ocreata'' associates with oak trees. The large fruiting bodies (the mushrooms) generally appear in spring; the cap may be white or ochre and often develops a brownish centre, while the stipe, ring, gill and volva are all white. ''Amanita ocreata'' resemble several edible species commonly consumed by humans, increasing the risk of accidental poisoning. Mature fruiting bodies can be confused with the edible '' A. velosa'', '' A. lanei'' or ''Volvopluteus gloiocephalus'', while immature specimens may be difficult to distinguish from edible ''Agaricus'' mushrooms or puffballs. Similar in toxicity to the death cap ('' A. phalloides'') and destroying angels of Euro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Death Cap
''Amanita phalloides'' (), commonly known as the death cap, is a deadly poisonous basidiomycete fungus, one of many in the genus ''Amanita''. Widely distributed across Europe, but now sprouting in other parts of the world, ''A. phalloides'' forms ectomycorrhizas with various broadleaved trees. In some cases, the death cap has been introduced to new regions with the cultivation of non-native species of oak, chestnut, and pine. The large fruiting bodies (mushrooms) appear in summer and autumn; the caps are generally greenish in colour with a white stipe and gills. The cap colour is variable, including white forms, and is thus not a reliable identifier. These toxic mushrooms resemble several edible species (most notably Caesar's mushroom and the straw mushroom) commonly consumed by humans, increasing the risk of accidental poisoning. Amatoxins, the class of toxins found in these mushrooms, are thermostable: they resist changes due to heat, so their toxic effects are not r ...

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

Douglas Fir
The Douglas fir (''Pseudotsuga menziesii'') is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (''P. menziesii'' var. ''menziesii''), Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and Mexican Douglas-fir (''P. menziesii'' var. ''lindleyana''). Despite its common names, it is not a true fir (genus ''Abies''), spruce (genus '' Picea''), or pine (genus ''Pinus''). It is also not a hemlock; the genus name ''Pseudotsuga'' means "false hemlock". Description Douglas-firs are medium-size to extremely large evergreen trees, tall (although only ''Pseudotsuga menziesii var. menziesii'', common name coast Douglas-firs, reach heights near 100 m) and commonly reach in diameter, although trees with diameters of almost exist. The largest coast Douglas-firs regularly live over 500 years, with the old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycorrhizae
A mycorrhiza (from Greek μύκης ', "fungus", and ῥίζα ', "root"; pl. mycorrhizae, mycorrhiza or mycorrhizas) is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry. In a mycorrhizal association, the fungus colonizes the host plant's root tissues, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in ectomycorrhizal fungi. The association is sometimes mutualistic. In particular species or in particular circumstances, mycorrhizae may have a parasitic association with host plants. Definition A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules such as sugars by photosynthesis and supplies them to the fungus, and the fungus supplies to the plant water and mineral nutrients, such as phosp ...
