CLASS: Fragilariophyceae
ORDER: Fragilariales
FAMILY: Fragilariaceae
- Striae composed of lineolate areolae
- Apical porefield at each pole
- Valves elliptical, linear or cruciform
The valves of Staurosirella are elliptical, linear or cruciform. Striae are composed of lineolate areolae. Apical porefields are present at both ends of each valve. Rimoportulae are absent. Neighboring cells are linked together at valve faces to form colonies.
Staurosirella includes the former Fragilaria lapponica, F. pinnata, F. leptostauron and their allies. Cells attach to substrates by short stalks secreted by the apical porefield. Members of the genus are common in both lentic and lotic waters.
