Tricholoma virgatum

Tricholoma virgatum, commonly known as the ashen knight, is a mushroom of the agaric genus Tricholoma. It was first described scientifically as Agaricus virgatus by Elias Fries in 1818, and later transferred to the genus Tricholoma by Paul Kummer in 1871. It is found in the deciduous and coniferous forests of Europe, North America, and China. The mushroom is inedible, speculated to be poisonous, and has a bitter and peppery taste and musty odor.

The cap is silvery and conical, with streaks of fibres. A similar species is Tricholoma sciodes.

Recent studies done on this mushroom have shown that its extract, after being submerged in methanol, can be effective in the prevention of diseases. This is due to the extract being antibacterial.
