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.
^Schäffer JC. (1774). Fungorum qui in Bavaria et Palatinatu circa Ratisbonam nascuntur Icones (in Latin). Vol. 5. p. 35. The illustration is plate 89. In volume 1 a description is given in German and Latin without the scientific fungus name (the descriptions are ordered according to the plate numbers). Also a short Latin description with the name Agaricus tigrinus is given on page 35 of volume 5; that should be the original description of Tricholoma tigrinum.
