Past Palynomorphs of the Month. Cylindrical neck flaring slightly at the oral end. Aperture is serrate to straight and comprises up to approximately one-half maximum width of the body chamber at the oral edge.
Flexure is distinct without obvious shoulder.
The base is flat or convex at the aboral end, with the basal edge rounded. Vesicle surface densely covered with small pointed simple spines that decrease in number in an oral direction on the neck. The body chamber may be spherical, ellipsoidal, or conical but is always at least two-thirds as long as the vesicle length. In the Nevada study area the species is restricted to the early Asgill to middle Caradoc. In the Eureka Quartzite Angochitina capillata is rare, but becomes common in the upper Pogonip Formation.
