Karvatuppea

Karvatuppea, scientifically known as Tricholoma vaccinum, is a species of fungus belonging to the genus Tricholoma. It is commonly found in coniferous forests across Europe and North America. The mushroom is characterized by its medium to large size, with a cap that typically measures between 5 to 12 centimeters in diameter. The cap's surface is often dry and covered in fine scales, giving it a shaggy appearance, and its color can range from reddish-brown to grayish-brown.

The gills of karvatuppea are adnate to slightly decurrent, meaning they attach to the stem and run slightly down its length. They are typically white or cream-colored and can become spotted with age. The stem is usually sturdy and fibrous, often tapering towards the base, and can be covered in a similar scaly texture as the cap.

Karvatuppea is considered an edible mushroom by some, though it is not widely consumed. It is often mistaken for other Tricholoma species, some of which are poisonous. Due to the potential for misidentification and the variable edibility, caution is advised. It typically fruits in late summer and autumn, growing solitarily or in small groups on the ground in association with spruce and pine trees, forming mycorrhizal relationships. The mushroom has a distinct, somewhat bitter taste and is sometimes described as having an earthy or phenolic odor.
