A gummy white substance "growing?" on the soil has appeared in several locations in our yard, often under mulch. Is it a fungus? what is it? what should we do about it? Thank you.

I suspect this is mycellium formed by the organisms that do the work of decomposition, but a couple of good quality photos would help us make a better identification.
I will look for your response.
Here are two images of the substance. One shows forming in place in the soil; the other shows sections of it after I peeled it off the dirt (also a side view to see its thickness).
This is indeed mycileum - the rooting system of fungi (mushrooms). It is common to see this growth in mulch that remains undisturbed for a while. It is an important part of the eco-system and will not cause harm to any of your plants.
If it bothers you, you can gently stir up the mulch so that it is drier.
