A Fungal Timepiece

IMG_1327 IMG_1328 IMG_1329

I’ve been looking for a while  for a suitable microorganism that might make the time-telling mechanism of a living timepiece. I have a kind of old fashioned but biological pocket watch in mind. I’ve just tested this fungus and it’s perfect!  The large fungal colony here is over two months old and it clearly shows evidence of some form of biological clock at work. Not unlike the rings that  we might find when a tree is cut down but the fungal rings develop over a much shorter time period.  All I need to do now is calibrate the cycle.

    • Thanks Patrik. The fungus was grown in the dark so I don’t think that it’s responding to light/dark.

      I’ve no idea what is making the patterns!
