Brasilonema terrestre C.L. Sant’Anna et J. Komárek in Sant’Anna et al. (2011:59) ( Fig. 12I–L View FIGURE 12 ).
Filaments forming fascicles conical, erect, short, 7.94–16.6 μm wide. Sheath firm, 0.91–2.68 μm wide, not lamellated, striate, yellowish-brown. Trichome cylindrical, slightly attenuated, false geminate branches rare, slightly constricted or not. Apical cell rounded. Cells cylindrical to short, 6.42–13.24 μm wide, 4.09–10.86 μm long, ratio l/w = 0.73. Cell content homogenous pale purple or yellowish-brown. Heterocyte cylindrical to ellipsoid, in intercalary position, 7.2–11.85 μm wide, 4.54–10.49 μm long. Hormogonia 6–13 cells, constricted, with intercalary heterocyte or not.
Habitat: —Metal plate.
Studied material: — PEUFR 55813, PEUFR 55815
Brasilonema cf. sennae (Komárek) C.L. Sant’Anna et J. Komárek in Sant’Anna et al. (2011: 57) ( Fig. 12M–P View FIGURE 12 ).
Filaments forming fascicles conical, erect on substrate, 10.01–15.92 μm wide. Sheath firm, 1.12–3.18 μm wide, 2– 4 lamellae, hyaline to brown. Apical cell rounded. Trichome cylindrical, false geminate branches rare. Cells sub-quadratic to short, 7.33–11.57 μm wide, 5.17–13.86 (15.02) μm long, ratio l/w = 0.88. Cell content granulated, olive-green. Heterocyte semielliptical, intercalary position, 7.67–14.03 μm wide, 4.35–13.02 μm long. Hormogonia up to 21 cells, constricted.
Habitat: —Steep slope next to the road.
Notes: —This morphotype differs from Brasilonema sennae by its habitat and cell l/w ratio.
Studied material: — PEUFR 55810
