FIGURE 1. A–AB. Roholtiella edaphica, sp. nov. A–G. Hormogonia. H–I. Young tapered filaments with conical end cell. J–Q. Calothrix-like filaments with swollen base and basal heterocyte. J. Filament with intercalary heterocyte (marked with arrow). K, N–O. Filaments false branched at the heterocyte. R. Young filaments with isopolar growth. S–W. Mature filaments. S. Tapered mature filaments with brownish colored sheath, diffluent at the ends (marked with arrow). T–U. Single false branching. X–AB. Formation and releasing of arthrospores. Strains used in this figure: CCALA 1055 = I–J, Q, AB; CCALA 1056 = D–E, U–V, Y; CCALA 1060 = L, W; CCALA 1061 = A, H, R–T, Z; CCALA 1062 = B–C, F, M, O, X; CCALA 1063 = G, K, N, P, AA. Scale bar applies to all figures, in A–Q and S–AB = 20 μm, in R = 100 μm.
