Taxonomy

It was first described in 1945 by the American mycologist William Murrill who discovered the species in Florida and classified it as Nolanea strobilomyces.^[3][4]

In 1947 the German mycologist Rolf Singer created the new genus Cystoagaricus and placed this species within it.^[5]

Etymology

The specific epithet strobilomyces derives from this mushroom's resemblance to members of the Strobilomyces genus as a result of the spiky squamules on the cap.^[3]
