Reestablishing the Occurrence of the Green Alga Hormotila mucigena in North America: Kansas and Michigan

The original report of Hormotila mucigena Borzi for North America was misidentified (Wujek and Wynne, 2016). It was shown earlier to be a stage of Rufusiella insignis (Hassall) Loeblich III (1967). This branched filamentous green alga, a taxon now placed in the order Chaetophorales and originally described from Sicily, is once again reported for North America from Douglas County, Lawrence, Kansas area and Isabella County, Michigan.
