Diderma sp?

[coffeeman]

looking to learn again …

I found a long-shed oak leaf hosting this myxo. Initially pure white, the fruit bodies turned slightly greyer over 3-4 days then split turning out brown spores with little in the way of capillitium threads.

The spores are spherical, 9.5-10 microns and typically a bit spikey.

I’m plumping for a Diderma species, maybe Diderma globosum …. could I be anywhere near? and is there really enough to get to a species?

I have found similar photos online (http://www.discoverlife.org/mp/20q?search=Diderma+globosum) that show the same regions of tiny little transparent dots, much smaller than the spores … what are these?

thanks for reading, regards

Alan

Hi Alan

I think you are in the right area.

The small transparent dots shown in your link are calcerous granules from the perideum.

Kind regards,

John
