All of them unidentified – but it would be nice to have a go. I only have 2 slime mould species on my pan-species list! 1.Growing on a branch in Beech and Oak woodland, in the gap between a crusty fungus species. Possibly a parasite of a lichen? Absolutely tiny, the photo is heavily cropped.

Large compared to number 1. I couldn’t find anything resembling spores in the microscope.

The fruiting body strongly resembles a jellyfish’s tentacles. The microscope photos are of what I think might be spores.

Often you need to look/photo different stages over a few hours or days to get anywhere with these. Even then often down to microscope I think! October 4, 2015 at 4:10 pm #36611Hi No. 1 looks like a Physarum species.
No. 2 Probably too early to guess a genus. You need to wait until the spores are being released to do the microscopy.
No.3 Is Ceratiomyxa fruticulosa

October 4, 2015 at 4:24 pm #36612Thanks both! I know slime moulds are tricky, but I wondered if any were immediately obvious (Ceratiomyxa fruticulosa for example). Do you know of any online resources for Physarum? October 4, 2015 at 8:22 pm #36613Physarum http://slimemold.uark.edu/martin.htm#Physarum Your Physarum looks very much like one I have had sat on my shelf for the last week..
There are several similar looking species – you could try Physarium nutans (=album) as a starting point.

October 5, 2015 at 6:37 am #36614Thanks John. Looking through the long list, the only one which seems to fit is P. nutans. The spores are the right size too.

You really need to use a key – you’ll rarely get an accurate ID of a myxomycete by browsing images. In my experience it’s better to go through the key first, decide what you think it is, then compare that with the available images of the spores, capilitium, nodes etc.
There are some keys on-line. One that I’ve used is Danish Myxomycetes, the key to Physarum is here:-

October 6, 2015 at 5:50 pm #36616Thanks again John! I got stuck on the second step though… can you suggest a good glossary??

Many thanks for link – it looks good! I’ve posted on Glamorgan Fungus Group Facebook page. I find these ‘creatures’ fascinating but with most I have difficulty identifying. I have contact with someone who knows a lot about them and have sent specimens for id’ing.
