Morchella steppicola

Morchella steppicola, the morel of the steppes, is a species of fungus in the family Morchellaceae (Ascomycota). Originally described from the steppic meadows of Ukraine in 1941,[1] this ancient relic of the last ice age corresponds to Mes-1, the earliest-diverging phylogenetic lineage in section Esculenta.[2]
