Compare Stauroneis kootenai

Bahls 2010

Compare

Stauroneis kootenai may be distinguished from Stauroneis gracilior by the lack of hyaline areas adjacent to the stauros. It differs from Stauroneis pikuni by having more robust valves and a smaller size. Stauroneis bryocola has rostrate apices. Stauroneis neohyalina has linear-lanceolate valves, rostrate to subcapitate apices and much finer striae and areolae. Stauroneis subgracilior has smaller valves with very narrow rostrate-capitate apices and very fine striae and areolae. Stauroneis schroederi has very narrow rostrate to subcapitate apices.
