Phlyctis argena (Spreng.) Flotow Whitewash lichen, blemished lichen
I cannot find a range map for this lichen. Identification: The name “whitewash lichen” is certainly fitting—this looks like dull white paint. It occurs in a thin layer (crustose) on tree bark (corticolous), on many different deciduous and some cone-bearing trees, in both open and sheltered conditions. It is found on red maple and cedar, for example. It does not have any apothecia (fancy lichen talk for fruiting bodies). Online References:
