Echinoderma is a genus of fungi in the family Agaricaceae.

Its members were for a long time considered to belong to genus Lepiota and the group was then circumscribed by French mycologist Marcel Bon in 1981 as a subgenus of Cystolepiota[1] before he raised it to generic status in 1991.

[2] This genus belongs to a group of genera allied to Lepiota with a white spore print, free (or almost free) gills, stipe easily separable from the cap and having a partial veil.

[3] Amongst the Agaricaceae it is characterized by the white spore powder, cap skin microscopically an epithelium with rounded cells, and a brownish cap and stipe, with brown scales.

[4] The name comes from the Greek "echinos" (ἐχῖνος) meaning a hedgehog or sea-urchin[5] and "derma" (δέρμα) meaning skin,[6] referring to the spiny cap surface.
