Lectotypification of Leptosiphonia schousboei and Ophidocladus simpliciusculus (Rhodomelaceae, Rhodophyta)

Abstract Lectotypes for the red algae Polysiphonia schousboei (=Leptosiphonia schousboei) and P. simpliciuscula (=Ophidocladus simpliciusculus) were designated here after the examination of original material housed in the Museum national d'Histoire naturelle de Paris (cryptogamy collections, Herbier National).
