Fruiting body of a slime mould found in Epping Forest. I am told it could be a species of Physarum.

Please add where and when your myxomycete was found.

Thanks Steve. A nice find and good photos. The dark colour is due to moisture I think and it may be lighter when dry. It will be interesting to see what the microscopy looks like and if you can identify it.

Hi Steve,

I agree with John that the dark colour is probably because of moisture.

It could be a Badhamia - the white capillitium is visible and it looks badhamoid (i.e. net-like) rather than physaroid (nodes connected by threads).
It is possibly B. utricularis. The shape of the sporothecae looks right for that species and the distinctive stalks are visible in some sporangia. I have collected both long stalked and short stalked to almost sessile fruiting bodies from the same substrate.
