Morchella purpurascens

Morchella purpurascens, the purple morel, is an ascomycete fungus in the family Morchellaceae. It was first described as a variety of Morchella elata by Emile Boudier in 1897,[1] based on a plate previously illustrated by Julius Vincenz von Krombholz.[2] It was then recombined as a distinct species in 1985 by Emile Jacquetant, and validated the following year by Jacquetant and Bon.[3][4] As with many other morel species, its taxonomical status remained for a long time a subject of debate, until an extensive phylogenetic and nomenclatural study in 2014 by Richard and colleagues confirmed this species' autonomy and matched it to phylogenetic lineage Mel-20.[5]
