Helvella leucophaea vs Helvella pithyophila

Bonjour,
Skrede et al. 2017, 2020 considèrent Helvella leucophaea comme synonyme d'Helvella pithyophila. D'autres la considèrent comme synonyme d'Helvella crispa. Cela semble basé sur un iconotype, mais ils proposent une épitypification future. Quelle est la meilleure position à adopter maintenant ?

Re : Helvella leucophaea vs Helvella pithyophila
Hi Nicolas,
at the moment you can't define if Helvella leucophaea (= H. pithyophila) is a species on its own, a variety of H. crispa or a synonym, because there is no type specimen available and still no epitype was designated.
But why not to follow Skrede et al. (2017)? They are able to define two different species - the one is Helvella crispa and the other one they call H. leucophaea.
Of course we have to wait untill they (or other authors) revise the Helvella-crispa-complex in detail. But up to then, I would call it Helvella leucophaea s. Skrede et al. 2017
Greetings,
Christoph
