Taxonomy and Systematics
Species: Boletus edulis Bulliard:1782
Notes on taxonomy: Boletus edulis has maintained its original name, which was given by Pierre Bulliard, a French botanist, in 1782. Bulliard did compete with the well-known Elias Magnus Fries, however Bulliard did manage to publish before Fries, thus its name remained. The genus Boletus contains approximately 30 boletes. Boletus edulis is known as the King Bolete due to its extremely large size and great taste. Boletus edulis is also referred to as a penny bun, porcino, or cep. The scientific species name was derived from the Latin word edulis meaning “edible”.
I keyed my specimen with Barron's "Mushrooms of Northeast North America: Midwest to New England" and confirmed with other sources.
Boletus edulis caps range from convex flat, and vary from 4.5-38 cm in diameter. The caps are smooth and can become a little wrinkled, additionally they are viscid when moist. They are typically brown to reddish brown. The pores are 2-3 mm wide and extend 1-3 cm deep. The pores go through significant color shifts throughout its life; white, then yellow to olive-yellow, and ending as a brownish-yellow. When bruised the pores stain a yellowish olive to a dull orangey cinnamon to a pale yellow-brown. The white to pale-brown stipes can grow to 2-12 cm tall and 2-7.5 cm wide. The stipes widen towards their base sometimes a creating a bulb and have a unique whitish reticulum on the upper portion. They are solid and have a partial veil. Boletus edulis spore prints are olive-brown. Boletus edulis typically fruit on the ground under conifers and can be found solo or in groups.
Boletus edulis are one of the most highly prized edible mushrooms in the world; they are even cultivated commercially. They are known to have a smooth and creamy texture, a nutty and meaty flavor, and a sourdough aroma.
Campus distribution and habitat
My Boletus edulis specimen was found solo, on the ground in the pine trees north of the tennis courts (just south of the ohio parking lot) at 1:00 pm on Monday, 19 September, 2011. Unfortunately my specimen had maggots in it and thus I could not taste their choice flavor.
Specimen found in the wooded patch amongst mixed hardwoods and conifers between the new houses and Dickinson on October 5, 2018. (MP)
