Status

This species should be identified by microscopy.

Description

Tetraspora lubrica forms a gelatinous thallus that feels slimy to the touch and falls apart with minimal handling. The species tends to grow as elongated gelatinous tubes but may form irregularly branched or perforated thalli. Although this species can usually be identified in the field, a microscope is necessary for confirmation.

When examined microscopically, the thallus is made of many spherical cells in a clear, gelatinous matrix. Often the cells will appear to be arranged in pairs or groups of four cells.

Where To Find

Tetraspora lubrica grows in freshwater ponds, ditches, streams and rivers. Although the species may be found throughout the year it is most conspicuous during the winter and early spring. This species may form blooms in slow-moving streams and ditches.

Relationships

Often found with Batrachospermum or Draparnaldia glomerata.
