Description: Aklnetes (spores) hyaline, tube-shaped, with rounded ends, (14–) 21–26 (–39) × 9–12 (–18.0) μm; Most spores showing a suture (broken, but still attached) at one end or both ends; Often pores visible at both ends of the spores.

(Sub-) Fossil occurence: No information

Co-occurence: No information

Modern occurence: Anabaena is a bloom-forming N-fixer with high light adaptation, having a competitive advantage under nitrogen-limiting conditions (Schreurs 1992; van Geel et al. 1994).

Palaeoenvironmental indication: Nutrient-rich conditions
