Muelleria
(Frenguelli) Frenguelli 1945 Category: Symmetrical biraphid
TYPE SPECIES: Muelleria linearis (O. Muller) Frenguelli
Image Credit: Sarah Spaulding
CLASS: Bacillariophyceae
ORDER: Naviculales
FAMILY:
- External proximal raphe ends deflected to one side
- Longitudial canals two, one on each side of the raphe
The outline of valves of Muelleria is linear, linear-elliptical or panduriform. The external proximal raphe ends are distinctive for their unilateral deflection. Distal raphe ends are branched. A longitudinal canal is present on each side of the raphe. Areolae are loculate. Living cells contain four plastids.
Muelleria gibbula and M. terrestris appear to be widespread in aerophilic habitats, in association with soils, mosses, and ephemeral pools of the mid-western and western United States. Several species within the genus are geographically restricted to the Arctic, Antarctic or South America.
