Caloboletus conifericola, commonly known as the dark bitter bolete, ^[1] is a species of mushroom-forming fungus in the family Boletaceae. It is found in the Pacific Northwest. ^[2]

Taxonomy

Caloboletus conifericola was first described by E.A.Dick & Wally Snell in 1969, as a member of the genus Boletus . However, this name was already preoccupied by a fungus described by the Soviet botanist Lidia Alexandrovna Lebedeva in 1951. Alfredo Vizzini proposed the name Caloboletus conifericola when he circumscribed the genus Caloboletus in 2014. ^[3]

Description

The cap of Caloboletus conifericola is grayish-brown to olive gray ^[4] and about 3-10 inches (7-25 cm) across. ^[1] The stipe is about 2-10 inches (5-15 cm) long and about 1-2 inches wide at the top. It starts out wider at the base, but more or less evens out as the mushroom grows older. ^[1] The pore surface is yellow, and the mushroom oxidizes blue when bruised. ^[1]

Similar species

Caloboletus conifericola can be confused with Caloboletus calopus and Caloboletus frustosus. Caloboletus calopus has a more reticulated stipe than C. conifericola, ^[2] and C. frustosus has a more cracked cap. ^{[4] [2]}

Habitat and ecology

Caloboletus conifericola is found in moss and leaf litter under conifer trees, especially grand fir and western hemlock. ^{[1] [2]} It is found fruiting during early fall, soon after the rains come. ^[1]
