Morchella punctipes used to be called "Morchella semilibera" before a recent DNA study (O'Donnell and collaborators, 2011) found support for the idea that Morchella semilibera is a strictly European species, and that our North American species are genetically distinct. Charles Peck (1903) noted that Morchella punctipes stem was adorned with small conical points. Thus, Peck coined the epithet punct - ipes (spotted - stem) and named a new species because, in his estimation, the usual half-free morel (Morchella semilibera) had a smooth stem. This vouchered specimen has small conical points covering the stem and combined with 2015 DNA analysis confirmed that this specimen is Morchella punctipes.
