Images

Images are not scaled. An individual that looks bigger than its neighbors might actually be smaller. See approximate size via the Observations section below. All images were made to fit within an area of 360px high and 200px wide.

Observations

Author: Tisza Bell 2010
Biovolume/cell 45.79
Length: 3-5 µm
Width: 1-1.5 µm

Description:

Cell appears alone and may initially look like a solitary B, but by changing the focus a clear sausage shaped envelope larger than the dark part of the cell will become apparent.

Notes:

Green Lakes: Morphotype K

Secondary Description

Author: Wehr, J. D. and Sheath, R. G., (eds.), 2003

Secondary Description:

Cells have heterokont flagellation, one or two chloroplasts, one or more contractile vacuoles, and a stigma. The protoplast is housed in a cylidrical to funnel-shaped lorica made of interwoven cellulose microfibrils. Species are determined on a basis of lorica and colony morhphology.
