TYLOPILUS FELLEUS Meaning and
Definition
-
Tylopilus felleus, commonly known as the bitter bolete, is a species of mushroom that belongs to the Boletaceae family. It is characterized by its large, fleshy cap, which ranges in color from reddish-brown to dark brown, often becoming darker with age. The cap can reach sizes of up to 25 centimeters in diameter and has a distinct convex shape, which may flatten out as it matures. The surface of the cap is typically dry and covered in a felty or scaly texture, giving rise to its scientific name.
The bitter bolete has a creamy yellow to pale yellow pore surface that stains blue when bruised or exposed. The pores are small and angular, and they are arranged in a tight, even manner. As the name suggests, this mushroom has a bitter taste, making it unpleasant to many people. The stipe (stem) is usually proportionally thick and cylindrical, often tapering towards the base. It is dry and can have a reddish-brown to grayish-brown color, sometimes exhibiting reticulation (a net-like pattern) or tiny raised dots.
This mushroom is mycorrhizal, meaning it forms a symbiotic relationship with specific tree species, such as oaks or beeches. It typically grows in forests, especially in North America and Europe, appearing in late summer and early fall. Although Tylopilus felleus is considered non-poisonous, it is generally avoided due to its bitter taste, which intensifies when cooked. Additionally, its texture can be tough and somewhat woody, making it less desirable for culinary purposes.
Etymology of TYLOPILUS FELLEUS
The word "Tylopilus felleus" is a scientific name that consists of two parts: the genus name "Tylopilus" and the species name "felleus".
The etymology of the genus name "Tylopilus" comes from two Greek roots: "tylo", meaning "bump" or "swelling", and "pilus", meaning "cap" or "hat". This name refers to the characteristic domed or bumpy cap found in many species within this genus.
The species name "felleus" is derived from the Latin word "fel", meaning "gall" or "bile". It is used to describe the bitter taste of the mushroom, which is common in many species of the Tylopilus genus.
