  Comments: Row 1 x33.5, y85.4; y94.3 row 2 x34; y91.6. Difficult taxonomy on this slide. Many looked similar to the A. exilis from other slides in this study unit. However, some look closer to A. thermalis. Some of the Gomphonema gracile specimens had pinched apices -- maybe a different designation is appropriate. Interesting slide.
 
Taxa Notes:
 
None.
