That makes sense. I wondered about something like that, since we have had
some serious droughts these past couple of years and I know the yard was
not a priority with the people who lived here before me. I don't think its
a fungus because it coincides too exactly with the shape of the tree on
both live oak trees. I'd like to see if feeding and watering will change
things. Will try that first before resorting to fungicides.
Thanks.
