Fungi are an enormous group of organisms that are so distinctive from both plants and animals that they are placed in their own kingdom. The main body of the fungus is composed of a multitude of microscopic threads (known as 'hyphae') which are located within the substrate (4). The fruiting body (such as the more familiar mushroom or toadstool) is produced to release spores and thus allows reproduction to occur. Fungi feed by absorbing nutrients from their surroundings.
Boletopsis grisea produces its squat fruiting bodies annually, between August and November (2).
Conservation
(

)
fornecido por Arkive
More sustainable forest management and a reduction in air pollution would help to secure the future of this fungus (2). In addition, Boletopsis grisea is a candidate species for listing in Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats, otherwise known as the Bern Convention (3)(5).
Description
(
Inglês
)
fornecido por Arkive
This squat fungus produces broad, pale grey caps, the surfaces of which are often cracked into scales (2). The solid stipe (or stem) is short and located in the centre of the cap; it is greyish in colour (2).
WARNING: many species of fungus are poisonous or contain chemicals that can cause sickness. Never pick and eat any species of fungus that you cannot positively recognise or are unsure about. Some species are deadly poisonous and can cause death within a few hours if swallowed.
Habitat
(
Inglês
)
fornecido por Arkive
Boletopsis grisea has a mycorrhizal relationship with Scots pine (Pinus sylvestris) and is therefore always found associated with this tree (3). These fungi are found in forests that are generally dominated by pine, with lichens and poor acidic soils (3).
Range
(
Inglês
)
fornecido por Arkive
Boletopsis grisea is found in the boreal forests of Europe, reaching into Asia and North America (2).
Status
(
Inglês
)
fornecido por Arkive
Short-listed for inclusion in the Bern Convention by the European Council for Conservation of Fungi (ECCF), and included on the Red Lists of 5 countries (3).
Threats
(
Inglês
)
fornecido por Arkive
This fungus is threatened by the destruction of the pine forests of its habitat (2). Air pollution and the overuse of fertilisers pose additional threats to survival (2).

Boletopsis grisea

fornecido por wikipedia EN
Boletopsis grisea is a species of fungus in the family Bankeraceae. The fruit bodies are gray, fleshy polypores that grow on the ground in a mycorrhizal association with Scots pine (Pinus sylvestris). It is found in Asia, North America, and Europe.
Taxonomy
The fungus was first described in 1874 as a species of Polyporus by American mycologist Charles Horton Peck in 1874, who made the type collection in Copake, New York.[2] Appollinaris Semenovich Bondartsev and Rolf Singer transferred it to Boletopsis in 1941.[3]
Description
The fruit body is a fleshy polypore that grows from the ground. The gray cap is convex and irregular with a dry surface. Underneath the cap are white pores. The stout stipe is the same colour as the cap.[2]
Distribution and habitat
Boletopsis grisea is found in Europe, and in both Canada and the United States,[4] growing on nutrient-poor acidic soils.[5] It has a mycorrhizal association with Scots pine (Pinus sylvestris), as well as lichens and heath plants as understorey.[5]
Status
B. grisea is a threatened species in Europe, where it has been short-listed for inclusion in the Berne Convention on the Conservation of European Wildlife and Natural Habitats by the European Council for Conservation of Fungi. It has been recorded from 15 countries, and appears on five Regional Red Lists. Threats to the fungus include deforestation, air pollution, and the use of fertilizers and lime used to increase timber production.[5]
Research
Research has identified p-terphenyl compounds that impart a free radical scavenging activity in laboratory tests.[6] Eight phenolic compounds have been isolated and identified from the fruit bodies, including three that inhibit the enzyme 5-lipoxidase.[7]
