Plasmodiocarp of Hemitrichia serpula. I initially thought that this was a pretzel coated with peanut butter (that's a thing, and quite good), dropped on the log by an earlier hiker during a snack break. Took me a full second, maybe two, to realize my mistake. Apparently quite common but I've never seen one again. #slimemould #slimemould #myxomycetes #PretzelSlimeMold
