Description:
Valves linear-lanceolate, slightly tumid in the middle with rounded capitate ends (L 35-40µm, W 4-5µm, 10-12 striae in 10µm). Axial area linear, narrow. Central area a broad wedgeshaped fascia. Raphe fissures straight to slightly curvate with central endings undulate. Central pores droplike, close together. Terminal fissures not always resolvable in LM, in SEM clearly deflected. Transapical striae strongly radiate in the middle, abruptly changing to convergent towards the ends. No longitudinal lines.

Notes:
Common in relatively dry (±45%), acid to slightly acid (pH 5,8-6,8) soils with higher specific conductance content (up to 1000µS/cm) and moderate nutrient conditions. Less common in mosses (mean F-value 4,2±2,3) but almost absent in waterbodies.Due to the confusion with P. similiformis, records of P. carteri are unclear. Based on pictures, this taxon seemed to be recorded on Kerguelen (Van de Vijver et al. 1998, 2001) and on South Georgia (Van de Vijver & Beyens (1997a).Before the publication of the Pinnularia monograph by Krammer (2000) this taxon was included within P. similiformis and treated likewise in the publications of Ile de la Possession (Van de Vijver & Beyens 1998, 1999a, 1999b). All slides with P. similiformis have been re-examined and apparently they all contained P. carteri. Both taxa can be distinguished by differences in width (smaller in P. carteri), outline and striation pattern (coarser in P. carteri).
