Tricholoma tigrinum is a gilled mushroom.

First described under the name Agaricus tigrinus by Jacob Christian Schäffer in 1774,[2] the species was transferred to the genus Tricholoma in 1871 by Paul Kummer.

[3] Schäffer's 1762 illustration of Agaricus tigrinus is now thought to represent Tricholoma pardinum (possibly due to an error) and some sources consider the name Tricholoma tigrinum to be a synonym of Tricholoma pardinum.

[4][5] However the authoritative Species Fungorum database maintains Tricholoma tigrinum as a separate species[6] though nowadays the name could scarcely be used in practice in this independent sense and a modern definition of it is not available.

See the Tricholoma pardinum article for more details of this story.
