Gatunek uznawany za amerykański, jednak autor taksonu jako podstawową cechę która wyróżnia go od Helvella albella podaje wywinięte na zewnątrz krawędzie kapelusza co wyraźnie widać u owocników mojej kolekcji.

Autorzy opracowań tego rodzaju podchodzą jednak z rezerwą do tego taksonu.

I. Skrede, T. Carlsen1, T. Schumacher, A synopsis of the saddle fungi (Helvella: Ascomycota) in Europe – species delimitation, taxonomy and typification (2017) autorzy zawarli jedynie dwie uwagi w stosunku do niego:

"Notes — Van Vooren & Frund (2010) adopted the binomial H. corbierei for this species, a disposition approved by us. Helvella corbierei represents the European H. stevensii sensu Dissing (Dissing 1966b, 2000). To support the lectotype (iconotype) selected by Van Vooren & Frund (2010), we have designated an epitype specimen from Switzerland in order to stabilize the use of the name. The sequenced specimens share identical rpb2 sequences and vary in one hsp site. The specimen from Western USA (Oregon) deviates from the European collections by two rpb2 and three hsp substitutions. Two specimens from North America referred to as H. compressa by Landeros et al. (2015) belong here (cf. Appendix 3)."

"The specimen in FH supplied partial sequences from hsp, rpb2 and LSU. A morphologically similar but molecularly divergent species was recently reported from the American continent under this name (Landeros et al. 2015); however, the published LSU sequences [JX 993052, AY544655] are suggestive of H. corbierei (cf. Appendix 3)."
