A bolete is a type of mushroom, or fungal fruiting body. It can be identified thanks to a unique cap. On the underside of the cap there is usually a spongy surface with pores, instead of the gills typical of mushrooms. A similar pore surface is found in polypores, but these species generally have a different physical structure from boletes, and have different microscopic characteristics than boletes. Many polypores have much firmer, often woody, flesh.

"Bolete" is the English common name for fungus species with caps that have this appearance.

Some, but not all boletes bruise blue.{{Cite web |last=Biggane |first=Eric |date=2015-07-30 |title=Identifying Boletus Mushrooms |url=https://www.wildfooduk.com/articles/identifying-boletus-mushrooms/ |access-date=2024-07-15 |website=Wild Food UK |language=en-GB}}

Taxonomy

The boletes are classified in the order Boletales. However, not all members of the order Boletales are boletes. The micromorphology and molecular phylogeny of the order Boletales have established that it also contains many gilled, puffball, and other fruit body shapes. Examples of these fungi include Chroogomphus, Gomphidius, Phylloporus, Paxillus, Tapinella, Hygrophoropsis, and Scleroderma.{{Cite web |title=The Genus Scleroderma (MushroomExpert.Com) |url=https://www.mushroomexpert.com/scleroderma.html |access-date=2024-07-15 |website=www.mushroomexpert.com}}

The genus Boletus was originally broadly defined and described by Carl Linnaeus in 1753, containing all pored mushrooms.{{Cite book |last=Prasher |first=I.B |url=https://books.google.com/books?id=eM7WCQAAQBAJ&dq=boletus+linnaeus&pg=PA29 |title=Wood-rotting non-gilled Agaricomycetes of Himalayas |publisher=Springer |year=2015 |isbn=9789401798563}} Since then, gradually other genera have been defined, such as Tylopilus by Karsten in 1881,{{Cite web |title=Tylopilus felleus, Bitter Bolete mushroom |url=https://www.first-nature.com/fungi/tylopilus-felleus.php |access-date=2024-07-15 |website=www.first-nature.com}} and old names such as Leccinum and Suillus resurrected or redefined.

Recently, the genus Boletus has been split up even more, creating new genera, such as Xerocomellus{{Cite web |title=CZECH MYCOLOGY Czech Mycology 60(1): 29–62 Xerocomus s. l. in the light of the present state of knowledge. - abstract |url=http://www.czechmycology.org/doi/cmy.60104.php |access-date=2024-07-15 |website=www.czechmycology.org |language=en}} and Caloboletus.{{cite journal |author=Vizzini A. |title=Nomenclatural novelties |journal=Index Fungorum |issue=146 |date=10 June 2014 |issn=2049-2375 |pages=1–2 |url=http://www.indexfungorum.org/Publications/Index%20Fungorum%20no.146.pdf}}

Ecology

Most boletes are mycorrhizal and are generally found in woodlands.{{Cite web |title=The Boletes (MushroomExpert.Com) |url=https://www.mushroomexpert.com/boletes.html |access-date=2024-07-15 |website=www.mushroomexpert.com}} There is also a parasitic bolete, Pseudoboletus parasiticus, which grows on Scleroderma citrinum.{{Cite web |title=Parasitic Bolete {{!}} NatureSpot |url=https://www.naturespot.org.uk/species/parasitic-bolete |access-date=2024-07-15 |website=www.naturespot.org.uk}}{{Cite web |title=Pseudoboletus parasiticus (MushroomExpert.Com) |url=https://www.mushroomexpert.com/pseudoboletus_parasiticus.html |access-date=2024-07-15 |website=www.mushroomexpert.com}} Another parasitic bolete is Buchwaldoboletus lignicola, which is a parasite to Phaeolus schweinitzii, the dyer's polypore.{{Cite web |last=Initiative |first=The Global Fungal Red List |title=Buchwaldoboletus lignicola |url=https://redlist.info/iucn/species_view/327206/ |access-date=2024-07-15 |website=redlist.info |language=en}}

Boletes are susceptible to infection by the fungus Hypomyces chrysospermus, also known as the bolete eater.{{Cite web |title=Hypomyces chrysospermus (MushroomExpert.Com) |url=https://www.mushroomexpert.com/hypomyces_chrysospermus.html |access-date=2024-07-15 |website=www.mushroomexpert.com}}{{Cite book |last=Arora |first=David |title=Mushrooms demystified: a comprehensive guide to the fleshy fungi |date=1986 |publisher=Ten Speed Press |isbn=978-0-89815-170-1 |edition=2nd |location=Berkeley}}

Edibility

Many boletes, such as the porcini (Boletus edulis), are edible and considered a delicacy. However, other boletes, such as Suillus and Xerocomellus are considered edible, but not choice.{{Cite web |last=Stevens |first=Michael Wood & Fred |title=California Fungi: Xerocomellus dryophilus |url=http://www.mykoweb.com/CAF/species/Xerocomellus_dryophilus.html |access-date=2024-07-15 |website=www.mykoweb.com}} Some boletes, such as Caloboletus and Tylopilus are too bitter to eat.{{Cite book |last1=Schwarz |first1=Christian |title=Mushrooms of the redwood coast: a comprehensive guide to the fungi of coastal northern California |last2=Siegel |first2=Noah |date=2016 |publisher=Ten Speed Press |isbn=978-1-60774-817-5 |location=Berkeley}} Other boletes, such as ones in the Rubroboletus genus, such as Satan's bolete (Rubroboletus satanas) are dangerously poisonous. Most poisonous boletes have red pores.{{Cite web |title=Boletus edulis - Mushrooms Up!
