Appears to be a species of Lycogala but I am not sure, maybe L. epidendrum or even terrestre. They are one of the few species to be found during the cooler months here.
You know in some areas of the world, the plasmodium does get large enough, that some people cook and eat them. Sort of like a raw oyster in consistancy I would imagine
Thanks for your comments folks ...hmmmm not sure about eating them .
Ken - Yes Lycogala sp. does look to be a possible - thanks. The two pics were taken some time apart - pic1 was taken yesterday (30th Oct) and pic2 was taken in mid May. They have a very different surface texture - so could they still be the same species of Myxo at different stages?
Lycogala sp. is known, as well as other myxo's at times, to change color as it matures. More than likely, if you keep an eye on them, they will turn a dark olive right before and during sporulation and the invasion of cryptic slime mold beetles.
An Excellent find Bruce, and beautiful pictures also. Do we have you looking under logs now in the UK? (I`m glad you did). It looks like a snowman dressed up for "All Hollows Eve"
