Unique Identification: Diatom Taxon: Urosolenia sp. Site name: Spirit Lake, Iowa Light type: not specified Magnification: 100x Submitted by: Mark Edlund Notes: These are resting spores produced by the freshwater diatom Urosolenia. They look very similar to chrysophyte cysts but are bipartite. The heavily silicified spores can be found in sediments; usually the lightly silicified vegetative valves of this diatom are not present. For more information see Edlund & Stoermer (1993. JOPL 9:55-61). Image Tags: siliceous transparent cyst spore heavily-silicified rounded bipartite diatom |

Unique Identification: Diatom Taxon: Chaetoceras elmorei Site name: Devils Lake ND Light type: not specified Magnification: 100x Submitted by: Mark Edlund Notes: This group of images shows various views of spores from the diatom Chaetoceros elmorei. Spores are produced by few inland diatoms. Spores are more heavily silicified than the vegetative cells and are often the only part of the diatom that is preserved in lake sediments. Chaetoceros spores are usually an indicator of saline conditions. Image Tags: siliceous army-helmet transparent colorless oval saline spore heavily-silicified diatom |
