FIGURE 10. Diagrams that illustrate the possible forms and branching patterns of colonies of Epistylis spp. given in Table 2. Colony forms: a, simple cluster; b–c, e–h, arborescent; d, cuneate (wedge-shaped, with all stalks terminating at the same level); branching patterns: a, irregular (no discernible pattern); b–d, symmetrically dichotomous; c, asymmetrically dichotomous; e symmetrically alternating; f, asymmetrically alternating; g, pinnate; h, umbellate. Notes: colonies such as 'b' and 'c' are sometimes described as fan-shaped (flabellate); cuneate colonies (d) are sometimes incorrectly described as umbellate, a term that can be used properly only to describe a pattern in which all of the 2o branches radiate in different planes from a single point (compare 'd' and 'h' to see the difference); pinnate colonies like those illustrated in 'g' are an extreme variant of the alternating pattern in which pairs of 2o branches arise from points so close together that they seem to be opposite one another.

Scale bar = 100 µm in 3–4 and 25 µm in 5–9.
