Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Q. Tang et al. 2020 | Thallus consisting of multicellular, uniseri- ate and branching filaments with intercellular septa. Filaments are typically constricted at septa. Branches typically emanate laterally from a cell in the central axis and subjacent to a septum. Lateral branches themselves can be septate. Maximally one branch per cell. Multiple orders of branches can occur, resulting in apical or upward growth. A subdiscoidal holdfast may be present. Cells typi- cally elongate, thin-walled, mostly cylindrical but globose, clavate, cyathiformanddoliformhetermorphiccellsareoccasionallypres- ent. Cell width gradually increases distally (or adapically). Apical cells round or capitate, sometimes bearing a narrow extension at the distal end. |
