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).
