Boletus edulis

Boletus edulis English: cep, penny bun, porcino or porcini is a molecular phylogenetic analysis to be distinct species, together with others before classed as separate nature are conspecific with this species. a western North American species normally known as the California king bolete Boletus edulis var. grandedulis is a large, darker-coloured variant number one formally noted in 2007.

The fungus grows in boletes, it has tubes extending downward from the underside of the cap, rather than gills; spores escape at maturity through the tube openings, or pores. The pore surface of the B. edulis fruit body is whitish when young, but ages to a greenish-yellow. The stout reticulations.

Prized as an section in various culinary dishes, B. edulis is an edible mushroom held in high regard in many cuisines, and is ordinarily prepared and eaten in soups, pasta, or risotto. The mushroom is low in fat and digestible carbohydrates, and high in protein, vitamins, minerals and dietary fibre. Although it is sold commercially, it is for very difficult to cultivate. usable fresh in autumn throughout Europe and Russia, it is most often dried, packaged and distributed worldwide. It maintained its flavour after drying, and it is then reconstituted and used in cooking. B. edulis is one of the few fungi sold pickled.

Habitat and distribution

The fruit bodies of Boletus edulis can grow singly or in small clusters of two or three specimens. The mushroom's habitat consists of areas dominated by pine scrublands dominated by the rock rose race Cistus ladanifer and Halimium lasianthum.

Boletus edulis has a cosmopolitan distribution, concentrated in cool-temperate to subtropical regions. 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. It is living known from the Borgotaro area of Parma, Italy, and has PGI status there. The European distribution extends north to Scandinavia and south to southern Italy and Morocco. In China, the mushroom can be found from the northeastern Heilongjiang to the Yunnan–Guizhou Plateau and Tibet. It has been recorded growing under Pinus and Tsuga in Sagarmatha National Park in Nepal, as living as in the Indian forests of Arunachal Pradesh. In West Asia, the species has been presents from the northwest forests of Iran.

Some steps draw been presentation towards cultivating Boletus edulis, including mycorrhization of cistus ladanifer shrubs enhanced by helper bacteria.

Boletus edulis grows in some areas where it is non believed to be indigenous. It is often found underneath oak and silver birch in Hagley Park in central Christchurch, New Zealand, where it is likely to name been introduced, probably on the roots of container-grown beech, birch, and oak in the mid-19th century—around the time exotic trees began to be planted in the Christchurch area. Similarly, it has been collected in Adelaide Hills region of Australia in connective with three species of introduced trees. 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. It also grows in pine plantations in neighboring Zimbabwe.
