Featured Slime Mold #2: Ceratiomyxa fruticulosa var. fruticulosa

Common name: Coral Slime, White-Finger SlimeCeratiomyxa fruticulosa mb.jpg

There are two varieties of this species, hence the super-long scientific name listed above. The other, Ceratiomyxa fruticulosa var. porioides can tend to cluster their tiny "icicles" in a dome shape. The one pictured here has a more random, filled-in placement... looking more like a blanket.

This is one of the more common slime molds, often seen under large, fallen trees after heavy rains. Attracted to damp, dark locations it can spread, covering the underside of the tree in little time. It's been my experience, that due to its mostly shielded location, it can be seen for a longer period of time than many other slimes.

I photographed this slime mold at Mass Audubon's Habitat Education Center & Wildlife Sanctuary in July, 2003. The icicles are really tiny, only getting to a few millimeters high. These slimes can usually be found between late June and early October.

You can see a better close up of this one here. Or you can visit Mushroom Observer and get a number of great shots.
