pond algae:
List for
my garden pond at Shewington.
Algae were settled on slides in the pond for a period, then allowed to grow on in filtered pond water.
Some identifications are unconfirmed ('?').

Coenochloris ? | Chlorophyte, coenobia of cells in multiples of 2 in a mucilaginous envelope | ||
Coleochaete orbicularis |
|
Chlorophyte, characterised by most cells having a sheathed seta (hair) |
|
Coleochaete irregularis |
|
The filamentous form occurs in 2 versions: one has a definite margin to the cell while the other appears to be surrounded by a watery mucilage |

Cymbella ?cistula |
+ |
Diatom |
|
Desmococcus |
+ |
Chlorophyte, cells in groups formed by division in 3 planes, most commonly found growing subaerially on trees, fences, etc. |
|
Dimorphococcus | Chlorophyte, cells at the end of branching gelatinous strands, but kidney-shaped rather than globular like Dictyosphaerium | ||
Dispora |
Chlorophyte. Not listed in FAFBI, but present in Algaebase |
||
Elaktothrix gelatinosa | Chlorophyte, colonial in a mucilage sheath | ||

|
The cells are less than 5µm broad: this is a Chaetophoracean, relative of Stigeoclonium | |
Mischococcus
|
Mischococcus, a Xanthophyte, is superficially similar to Dictyosphaerium, but the cells are in linear groups of 1-4 at the ends of gelatinous tubes, rather than in pairs at the end of dichotomously branching threads | ||
Mougeotia 20 µm. |
Chlorophyte, axial band chloroplast with pyrenoids more |
||
Mougeotia 25 µm. |
|||
Naegeliella |
|
Chrysophyte: these 2 adjacent images show the colony and the branching gelatinous hairs |
|
Navicula sp. |
Diatom |
||
Navicula protractoides |
Diatom |
||

+ |
Diatom |
|
Nostoc |
