Physarum or Diderma

Hi damon,
If there were lime-nodes in the capillitium then it would be Physarum but as we dont have a photo of frount then I dont think we are ever going to know. Maybe Physarales species would be the closes we can get to with a name.

On the other hand the long orange/red stalk and shape of sporotheca makes it quite distinctive.

Ouch !

I dont remember the microscopy observations and I didnt take any pix of them :( . What are the cases we could have seen?

Would you say Physarum over Diderma genus? As its in Africa, we probably could only go to genus anyhow.

If there was no ball in the cenetr (Columella) then I would also be concerend of this name. Was there any white lime-nodes among the Capillitium?

Thank you Clive

Yes you’re right! I dont know how I missed taking a pic of the front side of the fruiting body! I’ll be more careful next time. In completion to the photo N 0906, I’m adding a new photo that shows that the centre of the fruiting body is empty, it gives a vlear idea about how it opens (without a ball in the centre).

I would like to see the other side of an open fruiting body.

Thank you Damonbrunette !

Not so sure about Diderma miniatum (I dont know) this one opens totally, without having a ball in the center. Diderma opens differently!

Thank you !
