Width Range: 8-11 µm
Striae in 10 µm: 10-12

Description

Valves are linear-clavate with a broadly rounded headpole. In some specimens the headpole may possess an acute tip. The footpole is rounded. Raphe is filiform, straight and does not reach the margin at either pole. The two raphe branches are usually of unequal lengths. Striae are usually short and near the margin, but there may be isolated areolae extending into the broad axial area. The footpole has a higher striae density near the terminus. Stigmata, septa and pseudosepta are lacking.

EMAP Assessment

The Environmental Protection Agency (EPA) western Environmental Monitoring and Assessment Program (EMAP) study was completed during the years 2000-2004 (see citations at bottom of this page). Over 1200 streams and rivers in 12 western states (Arizona, California, Colorado, Idaho, Montana, Nevada, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming) were selected for sampling based on a stratified randomized design. This type of design insures that ecological resources are sampled in proportion to their actual geographical presence. Stratified randomized design also allows for estimates of stream length with a known confidence in several “condition classes” (good or least-disturbed, intermediately-disturbed, and poor or most-disturbed) for biotic condition, chemistry and habitat.
