Past Palynomorphs of the Month. Maximum width always greater than vesicle length. Vesicle wall composed of two layers. Base commonly convex, but may appear flattened. Operculum located at junction between collar and body chamber.
Vesicles are usually chain-forming.
Ornamentation is generally psilate, but on occasion it has been reported as appearing to be of a slightly spongy texture. The vesicle consists of two distinct layers and a reported external spongy membrane which is rarely found on the Nevada specimens. The spongy membrane is concentrated on the oral section of the vesicle when present in the Nevada specimens. In the study area, Desmochitina lata has been recovered primarily from the upper Copenhagen Formation, and rarely from the Eureka Quartzite in the western most portion of the Nevada study area. Desmochitina bransoni and Desmochitina hymenelytrun .
