Stipitochrysis monorhiza Korschikov forma (Chrysophyceae, Ochromonadales), the first New Zealand record of a rare freshwater alga

Abstract

Stipitochrysis monorhiza Korsch. is recorded for the first time in New Zealand as a component of a brown, epilithic crust on stones and boulders in a fast-flowing mountain stream in Arthur's Pass National Park. Illustrations of New Zealand material are provided together with examples of previous iconography. The New Zealand specimens appear to be a form of the type.
