Description

This bluish-gray crust was growing on sandy soil in abundance and I collected some thalli with a permit. The areoles are somewhat swollen and irregular and about 1 mm in diameter. The lecanorine apothecia are pale tan and, in some of the larger ones, become irregular thickened. The epihymenium is brown and the spores are hyaline, 8/ascus, simple, thin-walled and about 12 x 5 microns on average. The apothecia is K negative and the brown epihymenium dissolves in K.
