Calvatia sculpta [SEP] Taxonomy and naming
The species was first described in 1885 by American mycologist Harvey Willson Harkness, under the name "Lycoperdon sculptum". Harkness, who called it "a curious and strikingly beautiful species", found fruit bodies growing at elevations between in the Sierra Nevada mountains. Although he noted that "in appearance it differs so much from any species known to us, as to be almost deemed worthy of generic rank", he thought that placement in the puffball genus "Lycoperdon" was the most appropriate classification, despite its unusual cortex. Harkness's type collections were destroyed in the fires following the 1906 San Francisco earthquake. In 1904, Curtis Gates Lloyd considered the species better placed in "Calvatia", because of the resemblance of its deeply colored capillitial threads (coarse thick-walled cells found in the gleba) to those of "Calvatia caelata"; he called the species "Calvatia sculptum".
