Pics from a new location

[gpmatthews]

The top two pics are, I think Staurastrum (hirsutum?). Flat on and end on.

The third, I'd like some suggestions. There seems a a hint of flagella.

The samples were collected from an acidic pond at Sandgate, near Storrington in West Sussex, UK a couple of weekends ago. My usual locations tend to have neutral to alkaline water. I'll post a picture in Favorite Locations.

All pictures:

Zeiss Standard GFL Microscope
Ocular: Olympus P15
Objective: Leitz x40 NPL Fluotar ICT (DIC)
Substage: Leitz ICT (DIC)
Camera: Canon Powershot S50

So, the first two are of the same subject but different views very interesting subjects and pictures (going to look up the name now )

I think Staurastrum (hirsutum?).

or S. teliferum. Length of spikes indicate teliferum.

Species of third picture!? Did you see vibrating flagellae? And could you get a little closer?

Kind regards, Wolfgang

Unfortunately cannot provide any closer shots until I get a new sample. The individuals were stationary and hints of flagella only noticeable in (flash) picture.
