Should we create a “group” for these observations?

The problem is there are so many species of Lecidea with well-developed areoles of varying shades of brown. You need chemistry and things like color of the hypothecium to be sure which is which. (Although, there may only one or two common species in any one given area.) For example, in southern California, chances are this would be L. mannii (C+r I think). True L. atrobrunnea down here tends to have very dark flattened subsquamulose thalli, compared with this golden-brown extremely convex areolate thallus.
