Morchella tridentina is a cosmopolitan species of ascomycete fungus in the family Morchellaceae. Commonly referred to as the mountain blond or western blond morel in North America, it produces conical, grey to buff fruit bodies that are rufescent and grow up to 20 cm (7.9 in) tall and 5 cm (2.0 in) wide. This early-diverging species is distinct within the /Elata clade (black morels) due to its pale colours and has been described by many names in the past, including M. frustrata, M. quercus-ilicis, M. elatoides, M. elatoides var. elegans and M. conica var. pseudoeximia, all of which were shown to be synonyms. A widely distributed relict of the last Ice Age, M. tridentina is so far known from Argentina, Armenia, Chile, Cyprus, France, India, Israel, North America, Spain and Turkey.
