Observation 68692: Parmotrema tinctorum (Delise ex Nyl.) Hale
When: 2011-06-03
Who: zaca
No herbarium specimen

Notes: The change of color in relation to the specimen in MO68509 – bluish-grey and almost white at the margins of lobes, without a trace of green – initially made me thought that it was another species and, maybe even, another genus. But it seems that these changes are possible within the same species.

this is the second time that I confuse Parmotrema tinctorum with Parmelina pastilifera (see MO52255 ). Thanks, Jason, for the correction.

It also has C+ red medulla, and broad rounded lobes with abundant evenly-distributed granular isidia just like this. It can grow on either bark or rock.
