Discussion:Four plants, seven single leaves, 1.45-1.56 m. The fragile leaf tips are generally missing in the fossils. This feature allows isolated leaves with the characteristic cellular organization of Tortella (basal, hyaline, nonpapillose cells extending along the margins toward the leaf apex) to be identified as T. fragilis.
