ResumoA study of available specimens of Globulinella has resulted in a re- alignment of some species and a significant range extension. Globulinella globi- fera (Hampe) Steere is reported for the first time to the United States. Gyro- weisia benoistii Ther. is transferred to Globulinella and Gyroweisia obtusifolia Broth. is removed from synonymy. During the summer of 1973 a small pottiaceous moss was collected on a calcareous outcrop in the Chisos Mountains of Big Bend National Park, Brewster County, Texas. Several months later another specimen was collected on calcareous silt in the desert be- low the mountains. The specimens were identified as Globulinella globifera, resulting in a considerable range extension for the species. A similar extension, recently reported for G. peruviana (Sharp & Bowers, 1975), indicated the need for a critical reexamina- tion of the genus. The nomenclatural history of Globulinella began when Hampe (1870) described two species, Seligeria globifera and Trichostomum obtusifolium, from specimens col- lected by Strebel in Veracruz, Mexico. Several years later Miiller (1897) published the genus Globulina for a single species, G. boliviana. In a short note under the description, Miiller suggested Seligeria globifera Hampe might be placed in Globulina. In 1902 Brotherus made the combination, Globu- lina globifera (Hampe) C.Miill., attributing it to Miiller. At the same time he provided a new name for the later homonym Trichostomum obtusifolium Hampe, i.e., Gyroweisia obtusifolia Broth. Williams (1916) added a third species to Globulina, when he de- scribed G. peruviana for a small moss collected by Cook and Gilbert near Araranca, Peru. The first reexamination of the species of Globulina was undertaken by Hilpert (1933) in his study of Trichostomaceae. Hilpert recognized G. globifera and G. peruviana as
