It was placed in the subgenus Phlegmacium of the large mushroom genus Cortinarius.

[2] In 2022 the species was transferred from Cortinarius and reclassified as Thaxterogaster talimultiformis based on genomic data.

[3] The specific epithet talimultiformis refers to the similar features it shares with species Thaxterogaster multiformis and Thaxterogaster talus.
