Boletus regius (Boletaceae), commonly known as the Royal bolete or Red-capped butter bolete, is a large and impressive mushroom found in Britain and Europe, North America, and Australia.

When fully expanded, the caps of the Royal Bolete range from 5 to 20cm in diameter and the margin usually becomes wavy.

The King Bolete: California’s porcini. Though this magnificent mushroom is regarded as common and widespread in Northern California, I have only happened upon them once. This beautiful specimen was found that day, and the pasta dinner that resulted was by the far the finest cookery ever to come from my kitchen. [Boletus edulis var. grandedulis]

King Bolete - Boletus pinophilus 

With a complex taxonomy, and sometimes considered a subspecies of Boletus edulis, Boletus pinophilus (Boletaceae) is a species of edible bolete known for its pleasant smell and taste. It forms mycorrhizal relationships with pines (Pinus), fir (Abies), and spruce (Picea), and can be found in coniferous or mixed forests in Europe an America.

Reddish Brown Bitter Bolete - Tylopilus rubrobrunneus

This is a beautiful but very bitter tasting bolete, scientifically named Tylopilus rubrobrunneus (Boletaceae). It is found in North America, and is very common in some years, and seemingly absent in others.  

Tylopilus rubrobrunneus is one of the largest boletes in the genus, at times having a cap as wide as a dinner plate.

Orange Birch Bolete - Leccinum versipelle

Appearing only under birch trees in Europe and North America, Leccinum versipelle (Boletaceae) is commonly known as the Orange Birch Bolete. Although cap color is alluded to in the common names of several Leccinum species, with this group of boletes it is unwise to draw any conclusion from this very variable characteristic.

Frost’s Bolete  (Apple Bolete)

Boletus frostii (Boletaceae) is an American bolete with blood red cap, with red pores, red, webbed stalk, and all parts bruise blue.

Although Frost’s bolete is actually an edible mushroom, it is not recommended because it could be confused with other, poisonous red-pored boletes. Remember the watchword: “Pores of red—may put you to bed!”.

This species occurs in eastern United States, south to Mexico and Costa Rica.

Bitter Beech Bolete  (Scarlet-stemmed bolete)

This Bitter Beech Bolete, Boletus calopus (Boletaceae), clearly shows one of the distinctive characteristic of the species: the deeper red stem covered in a pale yellowish net pattern, and the irregularly lobed cap.

The Bitter Beech Bolete is found in many parts of mainland Europe (including the British islands) and North America.

As its common name suggests, this bolete is not edible.
