Horses in my dreams...

A few days ago I took a long walk in the lovely autumn weather. I ended up in one of those places I love in Warsaw that I like to call the Warsaw countryside. It's close to the centre, the landmark PKiN is clearly visible, but still has a nice feeling of serenity.

Mouldy cup

Last week I was at a conference. When I came back to work I found my coffee mug looking like the image above. Obviously something needed to be done. The first thing was of course to extract some mould and put it under the microscope. 

In an optical microscope a network of fibres can be seen. To have a closer look one can but a piece of the mould into the SEM. Then we see this.

Lots of tiny cells clinging to some long fibre like structures. A closer view can look like this.

or like this

Yeah, yeah... the colouring of that last image is a bit hopeless... I was tired. 

I really like these flower-like ends of the fibres.

Apparently mould is really beautiful close up. Another reason not to be too fast with washing your coffee-mug.
