A blob in our garden

Question

Overnight two nights ago, a yellow blob, foamy looking, appeared between an old rose and a bunch of lilies. It is about 25 cm (10 inches) long by about 7 inches wide. The color is light sand. Any one has an idea what this could be and come from?

Thanks

Answer 1

This is a slime mold, a colony of unicellular creatures that many people mistake for fungus. It is actually more closely related to amoebas. This one is probably Fuligo septica, which can be white or yellow.

Fortunately, they are harmless. But if you want to get rid of them, this article has some ideas:
