Where I live the conditions are very good for Myxos at the moment. Yesterday I saw a lot of the common Ceratiomyxa fruticulosa and a lot of Tubulifera arachnoidea. There was one example of T. arachnoidea which I just had to get a photo of.... this is exactly as I found it.

And the idea for 1958 film 'The Blob' with Steve McQueen may have been inspired by Mucilago crustacea!

Thanks Chris. I seem to be monopolising this thread.. but the woods were bountiful again today..

I think this is Phsyarum leucophaeum. It changed from colourless/white to this ethereal pink/orange tint and then to grey within the space of a few hours..

Superb photos, well done.
In the photos I took of P. leucophaeum it looked quite blue, I'm sure the surface shows a sort of thin-film effect and the colour depends on lighting and surrounding colours . I do notice on your first shot that the lime encrustation on the surface looks pink as well - and of course this would be white so I would suspect there is a pink colour cast to the whole image - nice effect though.

Thank you for your comments, John and Dave. Yes, colour varies massively depending on lighting. Those were taken using flash but I sometimes use Jansjos. I usually shoot manually, so aperature, shutter speed and flash power vary also. As I side note, I think using flash may be detrimental to immature myxos.

Slightly off piste but still containing a myxo, Stemonitopsis typhina, I believe. When looking for myxos, there are almost invariably specialised slime-mould beetles present, often in large numbers.

They usually pop in and out of photos, but this one wandered into view and had his lunch right in front of me.

I did some reading and these usually belong to the Leiodidae - this one is probably an Agathidium or Anisotoma, but they are tricky to get to species. They are usually round and there defence is to pull in their legs and head and play dead and roll off the substrate. Some also have specialised dimples, thought to carry spores and help distribute the myxo.
