This species is common in maritime chaparral on ancient stabilized sand dunes, where it occurs on twigs of a variety of shrubs. This specimen was on dead twigs of Artemisia californica, coastal sagebrush.
Thallus whitish-green, thin, strongly K+Y, C+O. Note: The Sonoran Flora describes B. oidalea as K-, but I think that is a typo. It is described as K+Y elsewhere. Apothecia plane becoming convex, essentially globose, lacking pruina. Hymenium strongly inspersed with oil drops, impossible to get a clear view of ascospores, IKI+blue fading clear.
Spores seemed to be 8/ascus, becoming brown, muriform, with 15-18 cells or difficult to count. Spores usually have unpigmented apices (see photo). Approx. Measurements (struggling to get microscope calibrated well at 40x): 34×13µm 38.5×14µm 34×12µm 32×11.5µm 47×17µm
