Eunotia montuosa

 

Eunotia naegelii

LM scalebar = 10 µm = 80 pixels.



Observations

Contributor: Paula Furey - March 2011
Length Range: 24-62 µm
Width Range: 2.7-4.4 µm
Striae in 10 µm: 11-14 in the center valve, 16-18 at the ends

Description

Ventral margin is concave. Dorsal margin is convex. The apices are set off by a change in slope of the dorsal margin. The ends are narrowed, extended, and rostrate. The helictoglossae are not visible in the LM. Striae are radiate. Areolae are unresolved in the LM.

Autecology Discussion

Eunotia mydohaimasiae is associated with wet walls, and can be epiphytic on bryophytes or associated with algal slime or epilithon.
