When: 2010-11-07

Collection location: Dabney Creek, Madison Co., Arkansas, USA [Click for map]

Who: Jason Hollinger (jason)

Specimen available

Notes:
on siliceous sandstone outcrop in shaded forest near ridge top

This is the only saxicolous, poriform Pertusaria with norstictic acid in the Ozarks, so microscopy unnecessary. The UV+ ice-blue is not mentioned, but was reliable among the several specimens I collected.
