Yellow knight

Tricholoma equestre

A species of Tricholoma, Also known as Canary trich

The thick, squat yellow knight mushroom sometimes grows into a saddle-shaped cap. This species is distinguished in the field from the Sulphur Knight mainly by its own lack of a distinctive smell. Older guides may list these mushrooms as edible, but they have been linked to several confirmed poisoning cases in which their toxins had caused painful muscle damage.

Cap Diameter:

5 - 13 cm

Odor:

Mild, mealy, not particularly distinctive.

Is Yellow knight Toxic?

Yellow knight has been linked to cases of rhabdomyolysis, a condition characterized by muscle damage and weakness, pain, stiffness, darkening of urine, and periods of nausea and sweating. Symptoms typically occur after consuming the mushroom in several meals over a two-week period. The toxic compound causing these symptoms has not yet been definitively identified. Although yellow knight is mycorrhizal with pines and found widely across North America, reports of poisoning are primarily from Europe, leading to speculation about possible species differences. Some instances of yellow knight poisoning have resulted in fatalities.

Type of poisoning

Rhabdomyolytic

Toxic Severity

Extreme toxicity

Incubation Period

4-48 hours

Poisoning Symptoms

One of the most common symptoms is severe muscle pain, tenderness, and weakness, especially in the shoulders, thighs, or lower back.
Degradation of muscle tissues leading to severe muscle soreness and fatigue.
General malaise including loss of appetite and feelings of dizziness.
Elevated body temperature accompanied by excessive sweating.
Dark-colored urine, indicating potential muscle breakdown products in the bloodstream.
Potential heart inflammation (myocarditis) and breathing difficulties.
