[2] Clitocybe amoenolens found in Morocco and parts of South Europe and C. acromelalga from Asia were noted to have habits more similar to Paralepista flaccida (formerly Lepista flaccida) than to other Clitocybe species.

Additionally the pileipellis and microscopic details of these species were distinct from others in the Clitocybe genus and related genera.

Genetic sequencing placed these species close to Cleistocybe and Catathelasma genera.

Acromelic acid A is a potent neurotoxin with a chemical formula of C13H14N2O7 which is associated with causing paralysis and seizures[3] The type species, Paralepistopsis amoenolens was previously classified as Clitocybe amoenolens and is commonly known as the paralysis funnel due to the harmful effects caused by consuming it.

[2] As of July 2022[update], Index Fungorum accepted 2 species of Paralepistopsis.
