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.
Entoloma sinuatum is a poisonous mushroom found across Europe and North America. Some guidebooks refer to it by its older scientific names of Entoloma lividum or Rhodophyllus sinuatus. The largest mushroom of the genus of pink-spored fungi known as Entoloma, it is also the type species. Appearing in late summer and autumn, fruit bodies are found in deciduous woodlands on clay or chalky soils, or nearby parklands, sometimes in the form of fairy rings. Solid in shape, they resemble members of the genus Tricholoma. The ivory to light grey-brown cap is up to 20 cm (7.9 in) across with a margin that is rolled inward. The sinuate gills are pale and often yellowish, becoming pink as the spores develop. The thick whitish stem has no ring.
Entoloma is a genus of fungi in the order Agaricales. Called pinkgills in English, basidiocarps are typically agaricoid, though a minority are gasteroid. All have salmon-pink basidiospores which colour the gills at maturity and are angular (polyhedral) under a microscope. The genus is large, with almost 2000 species worldwide. Most species are saprotrophic, but some are ectomycorrhizal, and a few are parasitic on other fungi. The type, Entoloma sinuatum, is one of several Entoloma species that are poisonous, typically causing mild to severe gastrointestinal illness.
Inonotus arizonicus is a plant pathogen. I. arizonicus is a locally common saprotrophic polypore that induces white rot in sycamore trees in southwestern North America. Host species include Platanus wrightii and Platanus racemosa. The fruiting bodies, shaped like hooves or a plate or a stack of plates, can appear on trunks, at the base of living trees, or on stumps or snags. In California this species is generally found south of the San Francisco Bay Area.
Clitopilus prunulus, commonly known as the miller or the sweetbread mushroom, is an edible pink-spored basidiomycete mushroom found in grasslands in Europe and North America. Growing solitary to gregarious in open areas of conifer/hardwood forests; common under Bishop pine along the coast north of San Francisco; fruiting shortly after the fall rains. It has a grey to white cap and decurrent gills.
Boletus barrowsii, also known in English as the white king bolete after its pale colored cap, is an edible and highly regarded fungus in the genus Boletus that inhabits western North America. Found under ponderosa pine and live oak in autumn, it was considered a color variant of the similarly edible B. edulis for many years.
Entoloma hochstetteri, also known as the blue pinkgill, sky-blue mushroom or similar names, is a species of mushroom that is native to New Zealand. The small mushroom is a distinctive all-blue colour, while the gills have a slight reddish tint from the spores. The blue colouring of the fruit body is due to azulene pigments. Whether Entoloma hochstetteri is poisonous or not is unknown.
Amanita magniverrucata, commonly known as the pine cone amanita, or great pine jewel, is a species of agaric mushroom in the family Amanitaceae. First described scientifically by American mycologists Harry Delbert Thiers and Joseph Ammirati in 1982, it is mycorrhizal and associates with the tree Pinus radiata, which is commonly known as the Monterey pine.
Cortinarius smithii, also known as the western red dye mushroom, is an agaric fungus of the genus Cortinarius. Originally named Cortinarius phoeniceus var. occidentalis by American mycologist Alexander H. Smith in 1939, it was renamed to honor Smith in 2012, after molecular analysis revealed that it was genetically different from Cortinarius phoeniceus. It is found in North America.
Amanita augusta, commonly known as the western yellow-veil or western yellow-veiled amanita, is a small tannish-brown mushroom with cap colors bright yellow to dark brown and various combinations of the two colors. The mushroom is often recognizable by the fragmented yellow remnants of the universal veil. This mushroom grows year-round in the Pacific Northwest but fruiting tends to occur in late fall to mid-winter. The fungus grows in an ectomycorrhizal relationship with hardwoods and conifers often in mixed woodlands.
Entoloma holoconiotum is a mushroom in the family Entolomataceae. It was originally described as Nolanea holoconiota by David Largent and Harry Thiers in 1972. Machiel Noordeloos and Co-David transferred it to the genus Entoloma in 2009. The species can be found in conifer forests in western North America.
Nolanea claviformis, or Entoloma claviforme, is a mushroom in the family Entolomataceae. Described as new to science in 2014, it is found in Guyana, where it fruits on humus under Dicymbe corymbosa. The type was collected in the Potaro-Siparuni region, in the Pakaraima Mountains, at an elevation of 710–750 metres (2,330–2,460 ft). The specific epithet claviformis/claviforme (club-shaped) refers to the shape of its stipe.
Entoloma medianox is a species of agaric in the family Entolomataceae. It is known from western North America, where it was previously referred to the European species Entoloma bloxamii or E. madidum. Molecular research, based on cladistic analysis of DNA sequences, has, however, shown that Entoloma medianox is distinct.
Aureoboletus flaviporus, commonly known as the viscid bolete, is a species of bolete fungus found in western North America, where it grows in ectomycorrhizal association with coast live oak, madrone, manzanita, and possibly with tanoak. In California, this mushroom appears during the rainy season in locations south of Mendocino County. This mushroom is "fairly common" but does not appear in large groupings, only as one-offs or small clusters in scattered locations.
Lepiota decorata, also known as the pink parasol, is an uncommon species of gilled mushroom found in North America. The cap of L. decorata usually has a speckled violet pattern, stains orange when scratched, and is about 4 to 8 cm in diameter.
Calonarius viridirubescens is a species of gilled mushroom. First described to science in 1997, this species was previously classified as Cortinarius viridirubescens, and is thus commonly known as the yellow-green cort.
Craterellus atrocinereus, commonly known as the black chanterelle or Californiablack chanterelle, is a species of edible fungus native to western North America. This uncommon species is a mycorrhizal associate of live oak, tanoak, and Oregon white oak in Oregon and northern California, where it is found most often in the vicinity of Monterey Bay. This species has a "fruity-cheesy" odor, and fruits in winter and spring. This bluish-gray to black chanterelle was previously considered to be Craterellus cinereus but was recognized as a distinct species in 2015. The specific name is a nod to C. cinereus, with the Latin prefix atro meaning dark and cinereus referring to its smoky gray coloration.
Caloboletus marshii, commonly known as Ben's bitter bolete, is a species of mushroom in the family Boletaceae. It is not poisonous, but it is too bitter to eat. It turns blue when cut or bruised, and it grows under live oak.
Xerocomellus diffractus, commonly known as the cracked-cap bolete, is a species of mushroom in the family Boletaceae. It is found in western North America.
