Observation 4490: Mycetozoa Bary ex Rostaf.

When: 2007-10-21

Collection location: Los Trancos Preserve, Palo Alto, California, USA [Click for map]

Who: Douglas Smith (douglas)

No specimen available

Not a fungus here, and I’m not a big fan of looking for slimy molds, although they are pretty cool things, very strange life forms.

Anyway, I just had to include these here, hadn’t seen them before. The mass of small white “eggs” on cords is pretty neat. On a very rotten, wet log, with the sparse grouping on the side, and the dense grouping on the bottom.

Looking at web photos…

Looking at the photos on the web, it looks like you are right. Ceratiomyxa fruticulosa is just all white, and semi-branched, with no “stalk”. Where these are attached to the substrate with a wire-like “stalk”.

So, I don’t know what these are, and I’m not sure how much I really want to know about slime-molds…

Stalks are present

In Ceratiomyxa, the stalk is the sporangium. It is all one unit. Here we have a stalk with a clearly defined sporangium on the tip of the stalk.
