Hi there
My second mystery of the evening was this strange structure which seems to be formed largely of small green algae with larger green algae and the odd diatom in amongst them. My camera does a poor job of picking up greens (or I do a poor job of setting it up so it shows greens as they look to the eye) so these appear to have brighter clearer greens through the eyepiece than the photos show. This was in a small sample from a little pond and was in some of the clumpy material from the bottom of the pot. The longer of the two fingers was about 900µ long and 100µ wide
Any suggestions of what it might be would be gratefully received
Many thanks and all the best
Ian
