Tricholoma equestre[edit]

Tricholoma equestre, commonly known as the "man on horseback"

Tricholoma equestre, commonly known as the "man on horseback," is a species of fungus in the family Tricholomataceae. It is a basidiomycete mushroom that has been traditionally consumed in various parts of Europe. However, recent studies have raised concerns about its potential toxicity.

Description[edit]

The cap of Tricholoma equestre is typically 5–12 cm in diameter, convex to flat, and often has a slightly depressed center. The surface is smooth and sticky when wet, with a distinctive yellow to greenish-yellow color. The gills are adnate to sinuate, crowded, and pale yellow, becoming darker with age.

The stipe (stem) is 3–8 cm long and 1–2 cm thick, cylindrical, and often has a slightly bulbous base. It is yellow, similar in color to the cap, and may have a fibrillose surface.

The spore print is white, and the spores are ellipsoid, smooth, and measure 6–8 by 3.5–5 µm.

Habitat and Distribution[edit]

Tricholoma equestre is found in coniferous and mixed forests, often growing in association with pine trees. It is widely distributed across Europe and parts of North America. The fruiting bodies typically appear in late summer to autumn.

Edibility and Toxicity[edit]

Historically, Tricholoma equestre was considered a choice edible mushroom. However, cases of rhabdomyolysis and other muscle-related symptoms have been reported following consumption, leading to concerns about its safety. The exact toxic compounds are not well understood, but it is advised to avoid consuming this species.

Related Species[edit]

Tricholoma equestre can be confused with other yellow-capped species of Tricholoma, such as Tricholoma flavovirens. Careful examination of morphological features is necessary for accurate identification.
