& Singer) Bas (1965)[3] Dissoderma paradoxum, which has the recommended English name of powdercap strangler in the UK,[4] is a species of fungus in the family Squamanitaceae.

[5] It takes over the host and replaces the cap and gills with its own but retains the original stipe, creating in effect a hybrid between the two.

[6] The species was first described as Cystoderma paradoxum by American mycologists Alexander H. Smith and Rolf Singer in 1948, based on specimens collected in Mount Hood National Forest in Oregon.

[2] Cornelis Bas transferred the species to the genus Squamanita in 1965.

[3] Recent molecular research, based on cladistic analysis of DNA sequences, has however shown that the species does not belong in Squamanita sensu stricto but in the related genus Dissoderma.
