Description

"Flavoparmelia baltimorensis" is a medium to large foliose lichen with a yellow green upper surface when dry; lobes rounded without pseudocyphellae; the upper surface with globose, pustule-like growths resembling isidia. Lower surface is black with a narrow brown zone at the margins.

Chemistry

Cortex, PD-, K-, KC+ yellowish, C- (usnic acid).
Medulla, PD+ red-orange, K-, KC+ pink, C- (protocetraric acid, with or without gyrophoric acid)

Habitat

On rock in shaded or exposed areas.

Similar species

The very similar, "Flavoparmelia caperata", usually grows on the bark of trees, but may be found on rock. The granular soredia produced in irregualar soralia distinguishes it from "F. baltimorensis" which lacks true soredia.

"Flavopunctelia flaventior" and "Flavopunctelia soredica" have pseudocyphellae in the upper surface of the thallus, and the medulla is C+ red.
