bay bolete blue

The metal scavenging effect of the methanolic extract of B. badius was 77.6% (superior than BHA, α-tocopherol, and BHT – 47.8%, 45.7% and 68.5%, repectively). The flesh of the fruit body is white, thick and firm when young, but becomes somewhat spongy with age. and fir (Abies spp.)

Tells: Bay-brown cap, often flat or convex. Common names for B. edulis vary by region. [119][120][121], Boletus edulis mushrooms are 9% carbohydrates, 3% fat, and 7% protein (table). White cap flesh stains yellow, then blue only by tubes. [81] Some reported cases of stomach ache following consumption of dried porcini have been attributed to the presence of this mould on the fruit bodies. [139], "Cep" redirects here. Early alternate names include Boletus solidus by English naturalist James Sowerby in 1809,[4] and Gray's Leccinum edule. When fresh, the angular pores of a Bay Bolete are a bright pale yellow colour, though this fades as the mushroom matures. [93] Caution should be exercised when collecting specimens from potentially polluted or contaminated sites, as several studies have shown that the fruit bodies can bioaccumulate toxic heavy metals like mercury,[94] cadmium,[95] caesium and polonium. Porcini and other mushrooms are imported into Italy from various locations, especially China and eastern European countries; these are then often re-exported under the "Italian porcini" label. The fruit bodies of B. edulis can be infected by the parasitic mould-like fungus Hypomyces chrysospermus, known as the bolete eater, which manifests itself as a white, yellow, or reddish-brown cottony layer over the surface of the mushroom. [68] The fungus forms a sheath of tissue around terminal, nutrient-absorbing root tips, often inducing a high degree of branching in the tips of the host, and penetrating into the root tissue, forming, to some mycologists, the defining feature of ectomycorrhizal relationships, a hartig net. The mushroom is low in fat and digestible carbohydrates, and high in protein, vitamins, minerals and dietary fibre. [58] It has been growing plentifully in association with pine forests in the southern KwaZulu-Natal Midlands in South Africa for more than 50 years and is believed to have been introduced with the import of pine trees. [18] The fruit bodies are highly perishable, due largely to the high water content (around 90%), the high level of enzyme activity, and the presence of a flora of microorganisms. My specimen meets all of the criteria for badius – yet it does not bruise. [51] It is common in Europe—from northern Scandinavia, south to the extremities of Greece and Italy—and North America, where its southern range extends as far south as Mexico. The monarch cultivated the fungus about his residence, Rosersberg Palace. Other Information: Oft-wrinkled stem colored like cap. [24] Ceppatello, ceppatello buono, ceppatello bianco, giallo leonato, ghezzo, and moreccio are names from Italian dialects,[25][26] and ciurenys or surenys is another term in Catalan. [83] An unidentified species of virus was reported to have infected specimens found in the Netherlands and in Italy; fruit bodies affected by the virus had relatively thick stems and small or no caps, leading to the name "little-cap disease". [40] Similar molecular technology has been developed to rapidly and accurately identify B. edulis and other commercially important fungi.

[107] Reconstitution is done by soaking in hot, but not boiling, water for about twenty minutes; the water used is infused with the mushroom aroma and it too can be used in subsequent cooking. The mushroom's habitat consists of areas dominated by pine (Pinus spp. macrostipitatus. ")[92], The flavour has been described as nutty and slightly meaty, with a smooth, creamy texture, and a distinctive aroma reminiscent of sourdough. It grows in coniferous or mixed woods on the ground or on decaying tree stumps. [18] It can also resemble the "bolete-like" Gyroporus castaneus, which is generally smaller, and has a browner stem. The scavenging effects of the methanolic extracts from the bay bolete was 68.7 (compare with 97.4 and 95.4 for BHA and α-tocopherol, respectively).

It keeps its flavour after drying, and it is then reconstituted and used in cooking. by Michael Kuo. [3] Hence, the name no longer requires the ratification of Fries' authority. [102] Porcini are a feature of many cuisines, including Provençal,[103] and Viennese. [109] Importantly for commercial production, porcini retain their flavour after industrial preparation in a pressure cooker or after canning or bottling, and are thus useful for manufacturers of soups or stews. Another cell type present in the hymenium is the cystidia, larger sterile cells that protrude beyond the basidia into the lumen of the hymenium, and act as air traps, regulating humidity. Alternatively, the mushrooms can be dried by cleaning with a brush (washing is not recommended), and then placing them in a wicker basket or bamboo steamer on top of a boiler or hot water tank. macrostipitatus. Yellow cap flesh blues & often tastes acidic. If you continue, you agree to view this website under these terms. [77], The mushroom has been noted to often co-occur with Amanita muscaria or A. rubescens, although it is unclear whether this is due to a biological association between the species, or because of similarities in growing season, habitat, and ecological requirements. [49] The spring king bolete (Boletus rex-veris), formerly considered a variety of B. edulis or B. pinophilus, is found throughout western North America. Babies may have clear fluid beads on the pores. [51] In China, the mushroom can be found from the northeastern Heilongjiang Province to the Yunnan–Guizhou Plateau and Tibet. Porcini have whitish pores while the other has pink. Some find its flavour as good as if not better than B. [33] It is well known from the Borgotaro area of Parma, Italy, and has PGI status there. [62] A 2004 field study indicated that fruit body production is enhanced by an open and sunny wood habitat,[63] corroborating an earlier observation made in a Zimbabwean study;[61] removal of the litter layer on the forest floor appeared to have a negative effect on fruit body production, but previous studies reported contradictory results. [69] Compatible hosts may belong to multiple families of vascular plants that are widely distributed throughout the Northern Hemisphere; according to one 1995 estimate, there are at least 30 host plant species distributed over more than 15 genera. [32] In youth, the pores are white and appear as if stuffed with cotton (which are actually mycelia); as they age, they change colour to yellow and later to brown. Smells STRONG. [130] B. edulis contains appreciable amounts of selenium, a trace mineral,[131] although the bioavailability of mushroom-derived selenium is low. Bay-brown cap, often flat or convex. porcini), means porcine;[15] fungo porcino, in Italian, echoes the term suilli, literally "hog mushrooms", a term used by the Ancient Romans[16] and still in use in southern Italian terms for this species. [45] It is lighter in colour than B. edulis, having a cream-coloured cap with pink tones;[46] often mycorrhizal with Ponderosa pine, it tends to grow in areas where there is less rainfall. All Rights Reserved. Owing to the globalization of the mushroom trade most of the porcini commercially available in Italy or exported by Italy no longer originate there.

[124] The carbohydrate component contains the monosaccharides glucose, mannitol and α,α-trehalose, the polysaccharide glycogen, and the water-insoluble structural polysaccharide chitin, which accounts for up to 80–90% of dry matter in mushroom cell walls.

The standard Italian name, porcino (pl. The colour is generally reddish-brown fading to white in areas near the margin, and continues to darken as it matures. grandedulis) can reach massive proportions, and is distinguished from B. edulis by a mature pore surface that is brown to slightly reddish. The basidia are thin-walled, mostly attached to four spores, and measure 25–30 by 8–10 µm.

The fungus produces spore-bearing fruit bodies above ground in summer and autumn. Does not bruise. Short, squat, high altitude mushroom. Being a Bolete, this type of mushroom has pores, not gills, underneath the cap. It is finely reticulate on the upper portion, but smooth or irregularly ridged on the lower part. [108], Like other boletes, porcini can be dried by being strung separately on twine and hung close to the ceiling of a kitchen. Common name: bay bolete. [31] The angular pores, which do not stain when bruised, are small—roughly 2 to 3 pores per millimetre. In France, they are used in recipes such as cèpes à la Bordelaise, cèpe frits and cèpe aux tomates. [50], The fruit bodies of Boletus edulis can grow singly or in small clusters of two or three specimens. [126], A comparative study of the amino acid composition of eleven Portuguese wild edible mushroom species showed Boletus edulis to have the highest total amino acid content. [64][65] A Lithuanian study conducted in 2001 concluded that the maximal daily growth rate of the cap (about 21 mm or 0.8 in) occurred when the relative air humidity was the greatest, and the fruit bodies ceased growing when the air humidity dropped below 40%. Science Notes: North American Boletes lists a parallel species, “var. Red-pink-tan on yellow cap. [100] They are eaten and enjoyed raw, sautéed with butter, ground into pasta, in soups, and in many other dishes. Boletus edulis (English: cep, penny bun, porcino or porcini) is a basidiomycete fungus, and the type species of the genus Boletus.

[52] They are widely exported and sold in dried form, reaching countries where they do not occur naturally, such as Australia and New Zealand. [51] Approximately 2,700 tonnes (3,000 tons) were sold in France, Italy and Germany in 1988, according to official figures. Italian chef and restaurateur Antonio Carluccio has described it as representing "the wild mushroom par excellence", and hails it as the most rewarding of all fungi in the kitchen for its taste and versatility. Red cap ages olive-brown, & gets deeply cracked/fissured. The cap colour appears to be affected by the amount of light received during its development, and may range from white in young specimens grown under thick canopy, to dark-brown, red-brown or yellow brown in those specimens receiving more light. [18] Considered a choice edible, particularly in France, Germany, Poland and Italy,[19] it was widely written about by the Roman writers Pliny the Elder and Martial, although ranked below the esteemed Amanita caesarea. Cap Tastes Bitter, Acrid, Astringent, or Peppery, Spore Print is 3- Pink-, Red-, Purple-, or Cinnamon-Brown. . [113][114], In Italy the disconnect with local production has had an adverse effect on quality; for example in the 1990s some of the dried porcino mushrooms exported to Italy from China contained species of genus Tylopilus, which are rather similar in appearance and when dried are difficult for both mushroom labourers and mycologists alike to distinguish from Boletus.
