Squamanita paradoxa: The Ultimate Mushroom Guide
About The Squamanita paradoxa Mushroom
Squamanita paradoxa is a species of fungus in the family Tricholomataceae. It is a parasitic fungus that grows on another fungus, Cystoderma amianthinum. Widespread in Europe and North America, it seems globally rare, though seen in Europe with slightly more frequency than in North America. Its host, however, is widespread, with no evidence of decline.
Other names: Powdercap Strangler.

Squamanita paradoxa Taxonomy & Etymology
In 1948 famous American mycologist Alexander H. Smith and German-born mycologist Rolf Singer described this remarkable mushroom based on fruitbodies collected in Mount Hood National Forest, Oregon USA. Smith and Singer gave the Powdercap Strangler the binomial scientific name Cystoderma paradoxum.
In 1965 Dutch mycologist Cornelis Bas (1928 - 2013) transferred this species to the genus Squamanita, establishing its currently-accepted scientific name as Squamanita paradoxa.
Squamanita, the genus name, suggests that mushrooms in this genus will be scaly (bearing squamules), while the specific epithet paradoxa reflects the puzzling nature of this species, which when it was first found was thought to be a new powdercap (Cystoderma) species.
