It has acquired an extensive synonymy in its taxonomic history, having been juggled between several genera. Petter Karsten transferred it to ''Ischnoderma'' in 1879 to give it the name by which it is currently known. Young, soft specimens may be cooked and eaten, but the species becomes hard and unpalatable later in life.Distribution
