This stuff covered half of a standing dead tree. Moist and rubbery to the touch. Bizarre. I wish I had a better camera for opportunities like these. Taken with macro lens….details aren’t so obvious with the naked eye.
Note: I could have tweaked the photo but I didn’t. After having on blurry pic, I found a much better one (the top photo) and added it.
A comment below identifies this as “poroids variation of ceratiomyxa”, and I think that sounds awesome. Long version of “slime mold”.
