Coleochaete: the sheathed bristle is indicative; it is actually pseudoparenchymatous; other species are more obviously so, or filamentous. [Bristle, synonymous with seta = a stiff projecting fibre] |

Stigeoclonium: other spp. have a less well-developed basal system than the one illustrated. This (S. farctum) also appears to have concentric rings in the basal disc, due to the chloroplasts in adjacent filaments being aligned. See branched filaments |
