Perhaps ...

The circled group of apothecia might well be L. dispersa in the strict sense, but they are rather tightly grouped and might be seated on a black thallus. Consequently this might be L. semipallida. The apothecial margins of this species usually have a slight creamy-yellow tint (rarely strongly yellowish), but I don't think white margins entirely rule it out.

Naming to the aggregate does seem best.
