Phase contrast light micrographs of our terrestrial isolates. (a) Isolate from Lake Baikal published previously (Bass et al., 2009). (b–d) Isolate WaAra (Wales, soil/ moss sample). Two different individuals (c and d are the same); this isolate was undistinguishable morphologically from the Baikal isolate, and with identical SSU rDNA sequence. (e–h) Isolate BAra1 (Amazon basin, associated with aquatic plants). Three different individuals (e and f are the same); cell body generally more compact than in the other soil isolates we observed. In all of these isolates, filopodia tend to be concentrated at the ends of cytoplasmic arms. The white arrow in b highlights a temporary anastomosis between two arms, and the black arrows in c and g show the typical pattern of rapid resorption of these arms when the cell changes direction. Scale bars: 20 μm in a–d; 10 μm in e–h.
