 The species was first described in the scientific literature by the Czech physician and mycologist Julius Vincenz von Krombholz in 1828 , under the name Morchella bohemica . The German naturalist Joseph Schröter transferred it to the genus Verpa in 1893 . Ptychoverpa bohemica is a synonym that was published by Frenchman Jean Louis Émile Boudier in his 1907 treatise on the Discomycetes of Europe ; the name is still occasionally used , especially in European publications . Boudier believed that the large , curved ascospores and the rare and short paraphyses were sufficiently distinct to warrant a new genus to contain the single species . Ptychoverpa has also been classified as a section of Verpa . The section is characterized by the presence of thick longitudinal ridges on the cap that can be simple or forked .
