Length: 14-16µm
Width: 4,6-6µm
Striae: 35-40 striae in 10µm

Description:

Valves rhombic-elliptical with obtusely rounded ends (L 14-16µm, W 4,6-6µm). Axial area very narrow, linear. No central area present. Raphe filiform, straight with simple central endings and terminal endings deflected towards the same side. Transapical striae not observable in LM (35-40 in 10µm), strongly radiate in the middle, convergent near the poles. In the centre, some shorter striae are placed between the longer ones.

Notes:

A. minuscula was found on two locations: in high abundances in a large lake in the Jardin Japonais (Pointe Basse) with a very high pH (i.e. 9,3) and rather high conductivity (220µS/cm) and secondly in quite wet soil samples taken in the immediate vicinity of the 'sources ferrugineuses' with a pH-value between 5,4 and 6,6 and relatively high amounts of chloride and sulfate. Relative abundances in the soil samples however, never exceeded 2%.King George Island (Schmidt et al. 1990), Antarctic Continent (Kellogg et al. 1980)
