Tricholoma caligatum

Tricholoma caligatum 1

Tricholoma caligatum, commonly known as the Vile Tricholoma, Knights Mushroom, or Vicious Knight, is a species of mushroom belonging to the genus Tricholoma. It is found in Europe and parts of North America, where it forms ectomycorrhizal relationships with various types of trees, particularly with oaks and conifers. This mushroom is notable for its distinctive appearance and the fact that it is considered inedible due to its bitter taste.

Description

Tricholoma caligatum features a cap that can range from 5 to 15 cm in diameter, initially convex before flattening out with age, often with a distinctive umbo at the center. The cap's surface is smooth and can vary in color from brown to greyish, sometimes with a violet tint. The gills are white to light grey, crowded, and emarginate, attaching to the stout, fibrous stalk. The stalk itself is white, sometimes discoloring with age, and measures 4 to 10 cm in height and 1 to 2.5 cm in thickness. The spore print of Tricholoma caligatum is white.

Habitat and Distribution

Tricholoma caligatum is primarily found in temperate forests, forming symbiotic relationships with hardwoods and conifers. It is most commonly associated with oaks and pines, thriving in both deciduous and mixed woodlands. This species prefers well-drained, sandy soils and is typically found in the autumn months. While it is widespread in Europe, its presence in North America is less common and primarily restricted to the eastern regions.

Edibility

This mushroom is considered inedible due to its bitter taste. There have been reports of gastrointestinal discomfort following its consumption, so it is advised to avoid eating Tricholoma caligatum. Its resemblance to other edible species of the Tricholoma genus necessitates caution during mushroom foraging to prevent accidental ingestion.

Conservation

As of the current knowledge, Tricholoma caligatum does not appear to be under any immediate threat. However, like many fungi, its populations are susceptible to changes in forest management practices and habitat destruction. Conservation efforts aimed at preserving its natural habitats are essential for ensuring the species' longevity.
