White plasmodium can be seen here:

Green plasmodium can be seen here:

The National Audubon guide says Stemonitis splendens “arises from a white mass”. I suspect the green and the yellow might be some other species. It could also be a genetic or phenotypic variant I suppose.

So the plasmodium can be white too?

I find Stemonitis splendens with yellow plasmodia only.

Hi Clive,

I just added a photo of some sporulating fruit-bodies that were adjacent to these white ones on the same log. They could be some other species of Stemonitis other than S. splendens. Regardless, this is chocolate brown tube slime, and the first photo is of a rarely seen late transitional phase between the white blobs and the brown tubes.

BTW, what do you think of these red guys?

I’m not even sure they are myxomycota.

I am more curious as to how Dan knows its Stemonitis splendens. It would not be identifiable until it has started to produce spores.

holy cow!
