Description:
Valves elliptical-lanceolate with blunt, rounded ends. (L 8,5-20µm, W 4,5 6,5µm, 30 striae in 10µm). RV: axial area lanceolate, raphe filiform without terminal fissures, central area stauroform, clearly reaching the valve margins. Striae consist of one row of quadrangular areolae. Internally the two raphid branches clearly curve towards the valve margins in the central area. ARV: lanceolate axial area, smaller towards the valve ends. Sometimes, in SEM, a small pore is visible at the end of the axial area.

Notes:
Common, but never in high frequencies (max. <16%) in dry, slightly acid, oligotrophic soils and relatively dry mosses (mean F-value 5,5±2,3). Observations in open waterbodies are scarce (rel. abund. <3%).Kerguelen (Bourrelly & Manguin 1954, Larson 1974, Le Cohu & Maillard 1983, Van de Vijver et al. 1998a, 2001), Macquarie Island (McBride et al. 1999).
