On April 9th of 1975, Vaucheria prolifera Dangeard was collected on the landward side of the dyke of the polder „Het Noorden” on the isle of Texel. V. prolifera occurred intermingled in mats with V. frigida (Roth) C.Ag., V. terrestris (Vauch) DC., and V. dillwynii (Web. & Mohr) C.Ag. in open places under a non-halophytic grass vegetation.
